Introduction of Client server Architecture,Types of Client Server Architecture,Advantages and Disadvantages
Transport Layer
Transport layer protocols provide services like reliable data transfer and connection establishment between applications on networked devices. They address this need through protocols like TCP and UDP. TCP provides reliable, ordered data streams using mechanisms like three-way handshake, sequence numbers, acknowledgments, retransmissions, flow control via sliding windows, and connection termination handshaking. UDP provides simple datagram transmissions without reliability or flow control.
Dynamic interconnection networks
Discussed different types of dynamic interconnection networks. Graphically demonstrated single and multiple bus interconnection networks. Discussed different types of switch based interconnection networks. Graphically shown the mechanisms of crossbar, single and multistage interconnection networks. Graphically explained the working principle of omega network, Benes network, and baseline networks.
Introduction to Application layer
The application layer is the top layer of the OSI model and controls how applications communicate over a network. It provides services for applications including mail, file transfer, domain name translation and network security. Protocols at this layer include HTTP, FTP, SMTP, DNS and others that allow applications to access remote files and exchange messages over the internet in a standardized way. The application layer hides the complexities of the underlying network from applications and ensures reliable and secure communication between devices.
Fault tolerance in distributed systems
Fault tolerance is important for distributed systems to continue functioning in the event of partial failures. There are several phases to achieving fault tolerance: fault detection, diagnosis, evidence generation, assessment, and recovery. Common techniques include replication, where multiple copies of data are stored at different sites to increase availability if one site fails, and check pointing, where a system's state is periodically saved to stable storage so the system can be restored to a previous consistent state if a failure occurs. Both techniques have limitations around managing consistency with replication and overhead from checkpointing communications and storage requirements.
Lecture 6 -_presentation_layer
The presentation layer is responsible for data representation, compression, encryption and formatting for transmission between applications. It encodes application data into messages and decodes received messages. Common data representations include ASN.1 and XDR. Lossy and lossless compression techniques are used to reduce file sizes. Encryption transforms plaintext into ciphertext using keys to protect confidentiality during transmission.

Distributed web based systems
This document provides an overview of distributed web-based systems, including the key components and technologies that enable them. It discusses the World Wide Web and how documents are accessed via URLs. It also describes HTTP and how connections and requests/responses work. Other topics covered include caching, content distribution networks, web services, traditional and multi-tiered web architectures, web server clusters, and web security protocols like SSL.
Minimization of DFA
This document discusses deterministic finite automata (DFA) minimization. It defines the components of a DFA and provides an example of a non-minimized DFA that accepts strings with 'a' or 'b'. The document then introduces an algorithm to minimize a DFA by identifying redundant states that are not necessary to recognize the language. The algorithm works by iteratively labeling states as distinct or equivalent based on their transitions and whether they are accepting states. This process combines equivalent states to produce a minimized DFA with the smallest number of states.
Process Management-Process Migration
This document discusses process migration in distributed systems. It defines process migration as relocating a process from its current node to another node, which can occur either before or during process execution. The key aspects of process migration covered include selecting processes to migrate, transferring process state such as CPU registers and address space, forwarding messages, and handling communication between related processes migrated to different nodes. Various process migration mechanisms and their tradeoffs are also summarized.
Mobile computing unit 5
The document discusses database issues related to mobile computing. It describes how mobile devices cache data from servers to reduce latency when the device is offline. The cached data is referred to as being "hoarded" in the device database. It discusses different database architectures including one-tier architectures where the database is specific to a mobile device and two-tier architectures involving client-server models. It also describes different cache invalidation mechanisms used to maintain consistency between cached data on devices and data on servers.
Ccna day1
The document provides information about the CCNA certification exam, including the exam number, total marks, duration, passing score, question types, and benefits of obtaining the certification. It also discusses common networking devices, network interface cards, hubs, switches, routers, common network topologies, and the functions of LANs, MANs and WANs. Finally, it introduces the OSI model and its seven layers.
Distributed network
A distributed system consists of multiple autonomous computers that are linked through software to appear as a single integrated system. Distributed systems have several desirable features including resource sharing, concurrency to allow multiple users simultaneous access, openness through public specifications, transparency so users are unaware of remote resources, scalability to grow by adding computers, and fault tolerance to continue functioning if components fail. Examples of distributed systems include the internet, university computing centers, and ATM networks.
Network Layer by-adeel
The network layer is responsible for packet forwarding including routing through intermediate routers. It controls the operation of the subnet and decides which physical path data takes. Routing is the process of moving packets from source to destination, usually performed by routers. Internetworking connects different network technologies like LANs and WANs using devices like routers. The network layer uses IP addressing to identify devices and enable routing. Private IP addresses identify internal devices while public addresses provide external internet access.
Logical Clocks (Distributed computing)
Logical clocks assign sequence numbers to distributed system events to determine causality without a global clock. Lamport's algorithm uses logical clocks to impose a partial ordering on events. Vector clocks extend this to also detect concurrent events that are not causally related, providing a full happened-before relation between all events. Each process maintains a vector clock that is incremented after local events and updated when receiving messages from other processes.

Levels of Virtualization.docx
There are 5 levels of virtualization implementation:
1. Instruction Set Architecture Level which uses emulation to run inherited code on different hardware.
2. Hardware Abstraction Level which uses a hypervisor to virtualize hardware components and allow multiple users to use the same hardware simultaneously.
3. Operating System Level which creates an isolated container on the physical server that functions like a virtual server.
4. Library Level which uses API hooks to control communication between applications and the system.
5. Application Level which virtualizes only a single application rather than an entire platform.
Computer Networks - Error Detection & Error Correction
This document provides information about error detection and correction techniques used in computer networks. It discusses different types of errors that can occur like single-bit and burst errors. It explains that redundancy is needed to detect or correct errors by adding extra bits. Detection techniques discussed include parity checks, checksumming, and cyclic redundancy checks. Parity checks can only detect odd number of errors. Cyclic redundancy checks use polynomial arithmetic to generate a checksum. Forward error correction allows detection and correction of errors by adding redundant bits to distinguish different error possibilities. Hamming code is an example of an error correcting code that can detect and correct single bit errors.
Architecture of Mobile Computing
The document describes a three-tier architecture for mobile computing. It consists of a presentation tier, application tier, and data tier. The presentation tier handles the user interface and rendering. The application tier controls transaction processing and accommodates many users. The data tier manages database access and storage. Middleware sits between operating systems and user applications to handle functions like network management and security across tiers. This three-tier architecture provides benefits like improved performance, flexibility, maintainability and scalability.
Multiple Access Protocal
Fast Ethernet increased the bandwidth of standard Ethernet from 10 Mbps to 100 Mbps. It used the same CSMA/CD access method and frame format as standard Ethernet but with some changes to address the higher speed. Fast Ethernet was implemented over twisted pair cables using 100BASE-TX or over fiber optic cables using 100BASE-FX. The increased speed enabled Fast Ethernet to compete with other high-speed LAN technologies of the time like FDDI.

8 drived horizontal fragmentation
This document discusses key concepts in distributed database systems including relational algebra operators, Cartesian products, joins, theta joins, equi-joins, semi-joins, horizontal fragmentation, derived horizontal fragmentation, and ensuring correctness through completeness, reconstruction, and disjointness of fragmentations. Horizontal fragmentations can be primary, defined directly on a relation, or derived, defined on a relation based on the fragmentation of another related relation it joins with. Ensuring correctness of fragmentations involves checking they are complete, the global relation can be reconstructed from fragments, and fragments are disjoint.
Network Layer
This document provides an overview of various topics related to the network layer, including IPv4, IPv6, ARP, RARP, mobile IP, routing algorithms, and routing protocols. It begins with basics of IPv4 such as its addressing scheme and role in interconnecting networks. IPv6 is then introduced, along with reasons for its development and key features like its large 128-bit addresses. Address Resolution Protocol (ARP) and Reverse ARP (RARP) are also covered. The document concludes by discussing routing algorithms like link-state and distance-vector, as well as protocols including RIP, OSPF, and BGP.
Multiprocessor architecture
This document discusses multiprocessor architecture types and limitations. It describes tightly coupled and loosely coupled multiprocessing systems. Tightly coupled systems have shared memory that all CPUs can access, while loosely coupled systems have each CPU connected through message passing without shared memory. Examples given are symmetric multiprocessing (SMP) and Beowulf clusters. Interconnection structures like common buses, multiport memory, and crossbar switches are also outlined. The advantages of multiprocessing include improved performance from parallel processing, increased reliability, and higher throughput.
recursive transition_networks
Recursive transition networks (RTNs) are used to define languages by representing them as graphs with nodes and labeled edges. Strings in the language are produced by paths from a start node to a final node, where the labels of the edges along the path combine to form the string. RTNs allow for defining infinite languages more efficiently than listing all strings, as adding edges increases the number of possible paths and strings. The power of RTNs increases dramatically when cycles are added to the graph, allowing for infinitely many possible paths and strings.
Network Security
This document provides an overview of computer security concepts, including risks, authentication, encryption, public key cryptography, wireless network security, and hacking tools and techniques. It discusses how attackers can sniff network traffic, crack wireless encryption, scan for vulnerabilities, and use social engineering to compromise systems. The document recommends maintaining up-to-date software, using strong passwords, limiting network access, and backing up data to help secure systems from potential threats.
Secure Communication (Distributed computing)
The document discusses secure communication and digital signatures. It begins by explaining symmetric cryptography and the key distribution problem. It then describes Diffie-Hellman key exchange, which allows two parties to agree on a secret key over an insecure channel without pre-shared secrets. It also covers RSA public key cryptography. The document discusses using hybrid cryptosystems that combine public key techniques for key exchange and symmetric encryption for bulk data. Finally, it explains how digital signatures using public key cryptography allow a message to be authenticated and integrity protected without encryption.

Network security.ppt
This document discusses key management and protocols for distributing public keys for use in public-key cryptography. It describes several problems with directly exchanging or posting public keys and introduces the concept of a public-key authority or certificate authority that can validate public keys. The document outlines some proposed solutions like a centralized public-key authority that maintains a directory of public keys or a hierarchical system of certificate authorities that can validate certificates within a public key infrastructure. It also discusses the X.509 standard format for public key certificates.
Protocols for Public Key Management
This document discusses key management and protocols for distributing public keys securely. It presents three solutions: appending public keys to emails, posting them on websites, and using a public key authority or certificate authority. The main challenges are authenticating users' identities and distributing updated keys securely. A public key authority maintains a directory of public keys but introduces a bottleneck. A certificate authority signs certificates that bind keys to identities, avoiding the need to be constantly online but requiring in-person identity verification. Standards like X.509 were introduced to format certificates uniformly. A public key infrastructure model is proposed using a hierarchy of certificate authorities to issue certificates at various levels.
13 asymmetric key cryptography
Asymmetric key cryptography uses two keys - a public key that can be shared publicly and a private key that is kept secret. This allows two parties who have never shared secrets before, like Alice and Bob, to communicate securely by encrypting messages with each other's public keys. Common asymmetric algorithms discussed are RSA, which uses prime number factorization, and ECC, which is based on elliptic curve discrete logarithms. A public key infrastructure (PKI) with certificate authorities (CAs) is required to authenticate users and manage public keys.

- One-time passwords which generate new passwords each time to prevent reuse of stolen passwords
- Challenge-response authentication which uses cryptographic functions to verify identity without transmitting passwords
- Public key authentication which uses digital signatures to authenticate users based on their private/public key pairs
- Kerberos which uses tickets and session keys issued by a trusted server to allow authentication between users and services on an network

This document discusses message authentication and digital signatures for verifying message integrity and authenticity. It describes how message digests and message authentication codes (MACs) allow parties to verify that messages have not been altered. Digital signatures provide non-repudiation by allowing recipients to verify the sender and prove to others that the sender did sign the message. Certificate authorities issue digital certificates that bind public keys to identities, allowing keys to be verified. A public key infrastructure (PKI) establishes a framework of certificate authorities, registration authorities, and protocols to manage certificates and keys.
Jerad Bates - Public Key Infrastructure (1).ppt
This document provides an overview of public key infrastructure (PKI). It discusses how PKI uses public key cryptography and digital signatures to establish secure communication channels between users. Certification authorities issue and sign digital certificates that map users' public keys to their identities, allowing other users to verify signatures and establish encryption keys. PKIs can be organized in different models like hierarchies or networks to distribute trust. Overall, PKI aims to provide the flexibility of key servers without requiring direct communication with a central authority.
Part2-Apps-Security.pptx
This document provides a high-level summary of Transport Layer Security (TLS):
- TLS establishes an encrypted connection between a client and server through a handshake that authenticates the server and negotiates encryption parameters.
- The handshake includes the client sending a ClientHello, the server responding with a Certificate and ServerHello, and agreeing on encryption keys.
- Once established, the connection uses the record protocol to securely transmit encrypted and authenticated data between the client and server. Sessions can also be resumed later using the agreed session ID.

An improved modulation technique suitable for a three level flying capacitor ...
This research paper introduces an innovative modulation technique for controlling a 3-level flying capacitor multilevel inverter (FCMLI), aiming to streamline the modulation process in contrast to conventional methods. The proposed
simplified modulation technique paves the way for more straightforward and
efficient control of multilevel inverters, enabling their widespread adoption and
integration into modern power electronic systems. Through the amalgamation of
sinusoidal pulse width modulation (SPWM) with a high-frequency square wave
pulse, this controlling technique attains energy equilibrium across the coupling
capacitor. The modulation scheme incorporates a simplified switching pattern
and a decreased count of voltage references, thereby simplifying the control
algorithm.

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.
Design and optimization of ion propulsion drone
Electric propulsion technology is widely used in many kinds of vehicles in recent years, and aircrafts are no exception. Technically, UAVs are electrically propelled but tend to produce a significant amount of noise and vibrations. Ion propulsion technology for drones is a potential solution to this problem. Ion propulsion technology is proven to be feasible in the earth’s atmosphere. The study presented in this article shows the design of EHD thrusters and power supply for ion propulsion drones along with performance optimization of high-voltage power supply for endurance in earth’s atmosphere.

Trusted intermediaries
- 1. Trusted Intermediaries and Security Handshake Pitfalls Prepared By Sukhvinder Singh PHD Scholar
- 2. Trusted Intermediaries (3rd Party) Its someone who sits between two parties, entities that don’t naturally trust each other and provides a bridge. Ex. Banks act as an intermediaries between depositors (seeking interest) and borrowers (seeking debit / withdrawal)
- 3. Who are the Trusted intermediaries in Network Security ? Why this third party is required?
- 4. Symmetric key problem Public key problem • How do two entities establish shared secret key over network? • When Alice obtains Bob’s public key (from web site, e-mail, diskette), how does she know it is Bob’s public key, not Trudy’s? Solution: • Trusted key distribution center (KDC) acting as intermediary between entities Solution: Trusted certification authority (CA)
- 5. Key Management In public key setup all the participants will have a pair of public key and private key Bob Alice Vinod Paveen (ev, dv) (eb, db) (ep, dp) (ea, da) If Alice wants to send message to Paveen. Alice has to get Paveen's Public Key. How the Alice will get the Paveen's Public Key?
- 6. There are two Distinct aspects of the use of public Key encryptions ---The Distribution of Public Keys. ---The Use of Public Key encryption to distribute secret Keys.
- 7. Distribution of Public Key 1 Public announcement Can be forged 2 Publicly available directory Can be tampered 3 Public-key authorities (KDC) Trusted 3rd party to maintain the directory 4 Public-key Certificates(CAs) (To Avoid the bottleneck of Public-key authorities they issue the certificates )
- 8. Public Announcement of Public Keys
- 9. Public Key Directory (PKD) ID Public Key Alice 1011001101011101 Bob 0110011110100011 Vinod 11001....................011 Praveen Suppose Alice wants to send message to Praveen This file maintained in the Public domain ( Like web sites etc) Alice Paveen (ep ) E ep (m) (ep ) PROBLEM : The Attacker can change the public key easily as it is Publically available What is the Solution ? (ep, dp)
- 13. How to obtain a certificate from Authorized party ? Bob Alice Autho (eAuth, dAuth) (eb, db) (ea, da) Suppose Bob needs certificates T || IDB || eb E dAuth ( T || IDB || eb ) = CB T || IDA || ea E dAuth ( T || IDA || ea ) = CA
- 14. How the Alice and Bob will use the certificate to communicate? BobAlice (eb, db) T || IDB || eb E dAuth ( T || IDB || eb ) = CB Alice will ask certificate from Bob. Then Alice has to verify the certificate by decrypting with Authority Public key CB D eAuth (CB) D eAuth (E dAuth ( T || IDB || eb ) ) = eb E eb (m)
- 16. Suppose I want to Modify or change the Public Key Sukh Auth (eAuth, dAuth) (es, ds) T* || IDS || es* Cs* = E dAuth ( T* || IDS || es* ) Cs = E dAuth ( T || IDS || es ) Cs* = E dAuth ( T* || IDS || es* ) New Certificate generated by the Authority
