Tor the onion router
Onion routing is an anonymous communication technique that encrypts and routes traffic through multiple network nodes, making it difficult to trace. It works by having a client connect to a Tor network node, which encrypts the connection and passes it to another node, and so on through several nodes, with each node only knowing the previous and next hops. This creates an encrypted circuit through the network that separates identification of the user from message routing to provide anonymity.
Introduction to Tor
Tor is an anonymity network that allows users to browse the web anonymously. It works by routing traffic through a series of volunteer servers, or relays, that encrypt and then randomly route data in an attempt to make it untraceable. The Tor browser bundles this routing technology to allow users to access the open web as well as "hidden services" anonymously. While Tor provides anonymity, it has some weaknesses including potential traffic analysis of autonomous systems and exit node eavesdropping. The presentation provides an overview of how Tor works and relays, how to use Tor safely, and some common services found on Tor.
Tor
The document provides an overview of the Tor Browser and how the Tor network functions to provide anonymity to users. It discusses how Tor uses onion routing to encrypt data and pass it through multiple nodes, or relays, so that no single point on the network can identify both the origin and destination of the data. It details how the Tor Browser is built on Firefox and includes extra privacy and security features. It also examines the technical aspects of how data is passed through the Tor network in cells and circuits to hide a user's location and activity.
Onion protocol
Onion routing is a technique for anonymous communication over a computer network. In an onion network, messages are encapsulated in layers of encryption, analogous to layers of an onion. The encrypted data is transmitted through a series of network nodes called onion routers, each of which "peels" away a single layer, uncovering the data's next destination. When the final layer is decrypted, the message arrives at its destination. The sender remains anonymous because each intermediary knows only the location of the immediately preceding and following nodes.
Onion routing was developed in the mid-1990s at the U.S. Naval Research to protect U.S. intelligence communications online. It was further developed by the Defence Advanced Research Projects Agency (DARPA) and patented by the Navy in 1998. Onion Routing is implemented The Onion Routing project or TOR project.

The document summarizes Tor (The Onion Routing), an anonymizing network that allows users to improve their privacy and security on the Internet. Tor works by routing traffic through several volunteer servers run by others around the world, hiding a user's location and usage from anyone conducting network surveillance or traffic analysis. It enables a wide range of uses including circumventing censorship, protecting government communications, and allowing dissidents and journalists to communicate more safely.
Tor
TOR (The Onion Routing) is a free tool that allows anonymous use of the internet. It was developed by the US Naval Research Laboratory. TOR anonymizes internet traffic by routing it through several volunteer relays run by the TOR network, encrypting the traffic layer by layer and preventing others from seeing the user's IP address. Various groups use TOR including normal users, journalists, activists and law enforcement to maintain anonymity online, though the final link in the routing is not encrypted and slow network speeds are a limitation. Proper security measures must be taken when using TOR to ensure privacy is maintained.

It was developed in the late 1990s and patented by the US Navy. Tor is the predominant technology that uses onion routing today. It encrypts data in successive layers to hide the origin, destination, and contents of messages as they pass through intermediate nodes. This provides strong anonymity and unlinkability between senders and receivers.
Tor Presentation
Onion Routing (Tor) is an anonymity network that allows users to securely communicate on the internet without compromising their privacy. It works by routing traffic through several servers, making it impossible for observers to trace the connection back to the user. Tor is the most widely used implementation of the Onion Routing design and improves upon the original design by allowing any server along the circuit to act as an exit point, making it harder to determine where traffic originated. Individuals, organizations, and governments all use Tor to keep communications private.
TOR... ALL THE THINGS
The global Tor network and its routing protocols provide an excellent framework for online anonymity. However, the selection of Tor-friendly software for Windows is sub-par at best.
Want to anonymously browse the web? You’re stuck with Firefox, and don’t even think about trying to anonymously use Flash. Want to dynamically analyze malware without letting the C2 server know your home IP address? You’re outta luck. Want to anonymously use any program that doesn’t natively support SOCKS or HTTP proxying? Not gonna happen.
While some solutions currently exist for generically rerouting traffic through Tor, these solutions either don’t support Windows, or can be circumvented by malware, or require an additional network gateway device.

Tor browser
Tor is an anonymizing tool that protects users' privacy and anonymity online. It works by bouncing communications around a distributed network of volunteer-run relays around the world, making it difficult to trace the origin or destination of a user's traffic. Originally developed by the U.S. Naval Research Laboratory to protect government communications, Tor is now used freely by people seeking to browse the web anonymously, as well as journalists, activists, and others seeking to circumvent censorship or avoid surveillance.
ONION Routing - Jovial learning
Onion routing provides anonymity to users on the internet. It works by encrypting data multiple times and routing it through several intermediate servers, known as onion routers, hiding the origin and destination from each router. When a user wants to communicate anonymously, onion routing first establishes a encrypted circuit through the routers. It then opens a stream through this circuit to send data back and forth between the user and destination while preserving anonymity. Each router only knows the previous and next hops in the circuit, not the complete path. Periodically, new circuits are formed to further improve anonymity.

Introduction to anonymity network tor
This second-generation Onion Routing system addresses limitations in the original design by adding perfect forward secrecy, congestion control, directory servers, integrity checking, configurable exit policies, and a practical design for location-hidden services via rendezvous points. Tor works on the real-world Internet, requires no special privileges or kernel modifications, requires little synchronization or coordination between nodes, and provides a reasonable tradeoff between anonymity, usability, and efficiency.

It works by measuring the P300 brainwave, which is emitted if the presented stimulus matches information in a person's memory. Brain fingerprinting has applications in national security, medical diagnosis, advertising, and criminal justice by analyzing whether specific memories are present or absent from a subject's brain.
Survey on Efficient and Secure Anonymous Communication in Manets
Mobile ad-hoc networks require anonymous communications in order to thwart new wireless passive attacks; and to protect new
assets of information such as nodes locations, motion patterns, network topology and traffic patterns in addition to conventional identity and
message privacy. The transmitted routing messages and cached active routing entries leave plenty of opportunities for eavesdroppers.
Anonymity and location privacy guarantees for the deployed ad hoc networks are critical in military and real time communication systems,
otherwise the entire mission may be compromised. This poses challenging constraints on MANET routing and data forwarding. To address
the new challenges, several anonymous routing schemes have been proposed recently.

Hybrid protocols like Zone Routing Protocol (ZRP) that combine proactive and reactive approaches are also examined. The document provides illustrations and comparisons of the routing mechanisms and characteristics of these important MANET routing protocols.
Onion
Onions are a species in the genus Allium that are native to Central Asia. They have upright green leaves attached to a swollen bulb underground. Common varieties include red, white and yellow onions. Different varieties bulb at different daylight hours, with long day bulbs requiring more light. Onions are available seasonally from spring through winter.
VPN Virtual Private Network
VPN allows distant networks and computers to securely connect over the internet. It uses authentication, tunneling, and encryption. The VPN workflow involves a client connecting to a VPN server, which allows the client to access resources as if it was on the local network. Popular VPNs include Microsoft, Cisco, and OpenVPN but the server and client must be compatible. VPNs offer security benefits but can be difficult to configure and require high-speed internet connections.

Ip spoofing ppt
IP spoofing involves modifying packet headers to disguise a hacker's identity by using a spoofed IP address. There are several types of attacks that use IP spoofing, including blind spoofing where the attacker is not on the same subnet and man-in-the-middle attacks where the hacker intercepts communications. While IP spoofing has been discussed since the 1980s, recent studies found over 30,000 spoofing attacks per day. Preventing IP spoofing requires techniques like validating source IP addresses, filtering spoofed addresses, and encrypting trusted network communications.
IP Spoofing
IP spoofing involves falsifying the source IP address of packets sent over the Internet in order to gain an illegitimate advantage or perform malicious acts. There are several types of spoofing, but IP spoofing is used to impersonate another computer in order to access restricted networks or obtain sensitive information. Attackers use IP spoofing in denial of service attacks by flooding victims with spoofed packets to overwhelm their resources. Defenses against IP spoofing include filtering packets at routers to validate source addresses and using cryptographic network protocols to authenticate communications.

Spoofing
This document discusses IP spoofing, which is a technique hackers use to gain unauthorized access to computers. It does this by forging the source IP address of messages, making it appear they are coming from a trusted host. Two main techniques are using an internal IP address or an authorized external address. IP spoofing is commonly used in denial of service attacks and network intrusions by defeating security like authentication based on IP addresses. It allows impersonating trusted computers and intercepting communications. However, IP spoofing alone does not fully hide one's identity as responses will go to the spoofed address rather than the actual source.
Onion Routing.ppt
Onion routing - an application independent infrastructure for private communication over a public network.
I P S P O O F I N G
IP spoofing involves an attacker using a spoofed IP address to gain access to information or systems. There are several types of attacks that use IP spoofing, including blind spoofing where the attacker does not see return packets, man-in-the-middle attacks by intercepting traffic, and source routing attacks where the attacker specifies their system is in the packet route. Defenses include not relying on IP-based authentication, using router filters to block spoofed packets, and using random sequence numbers to prevent prediction. While less common now, application spoofing remains a threat if programs are not properly configured.

For the full video of this presentation, please visit: https://www.edge-ai-vision.com/2024/06/temporal-event-neural-networks-a-more-efficient-alternative-to-the-transformer-a-presentation-from-brainchip/
Chris Jones, Director of Product Management at BrainChip , presents the “Temporal Event Neural Networks: A More Efficient Alternative to the Transformer” tutorial at the May 2024 Embedded Vision Summit.
The expansion of AI services necessitates enhanced computational capabilities on edge devices. Temporal Event Neural Networks (TENNs), developed by BrainChip, represent a novel and highly efficient state-space network. TENNs demonstrate exceptional proficiency in handling multi-dimensional streaming data, facilitating advancements in object detection, action recognition, speech enhancement and language model/sequence generation. Through the utilization of polynomial-based continuous convolutions, TENNs streamline models, expedite training processes and significantly diminish memory requirements, achieving notable reductions of up to 50x in parameters and 5,000x in energy consumption compared to prevailing methodologies like transformers.
Integration with BrainChip’s Akida neuromorphic hardware IP further enhances TENNs’ capabilities, enabling the realization of highly capable, portable and passively cooled edge devices. This presentation delves into the technical innovations underlying TENNs, presents real-world benchmarks, and elucidates how this cutting-edge approach is positioned to revolutionize edge AI across diverse applications.From Natural Language to Structured Solr Queries using LLMs
This talk draws on experimentation to enable AI applications with Solr. One important use case is to use AI for better accessibility and discoverability of the data: while User eXperience techniques, lexical search improvements, and data harmonization can take organizations to a good level of accessibility, a structural (or “cognitive” gap) remains between the data user needs and the data producer constraints.
That is where AI – and most importantly, Natural Language Processing and Large Language Model techniques – could make a difference. This natural language, conversational engine could facilitate access and usage of the data leveraging the semantics of any data source.
The objective of the presentation is to propose a technical approach and a way forward to achieve this goal.
The key concept is to enable users to express their search queries in natural language, which the LLM then enriches, interprets, and translates into structured queries based on the Solr index’s metadata.
This approach leverages the LLM’s ability to understand the nuances of natural language and the structure of documents within Apache Solr.
The LLM acts as an intermediary agent, offering a transparent experience to users automatically and potentially uncovering relevant documents that conventional search methods might overlook. The presentation will include the results of this experimental work, lessons learned, best practices, and the scope of future work that should improve the approach and make it production-ready.

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?
