This document describes the Byte Rotation Encryption Algorithm (BREA), a symmetric key block cipher algorithm that encrypts plaintext blocks in parallel using multithreading. BREA uses byte-rotation techniques and monoalphabetic substitution with a randomly generated 16-byte matrix. It provides an example of encrypting a plaintext block. BREA is described as being fast, requiring few computer resources, and providing secure encryption. Future work may implement BREA on multiprocessor systems to further improve encryption speed through parallelization.

Byte Rotation Algorithm
This document proposes a new encryption algorithm called Byte Rotation Encryption Algorithm (BREA). BREA is a symmetric key, block cipher that encrypts fixed-length blocks of 16 bytes using byte rotation and a randomly generated 16 byte key matrix. It employs a multithreading model to encrypt blocks in parallel, improving encryption speed. The algorithm assigns numbers 1-26 to letters, adds the plaintext and key matrices, then rotates rows and columns before replacing values with letters to generate the ciphertext. BREA is designed to be faster and require fewer resources than previous algorithms while still providing secure encryption.
Modes of Operation
The document discusses different modes of operation for block ciphers. It describes four main modes: Electronic Codebook (ECB), Cipher Block Chaining (CBC), Cipher Feedback (CFB), and Output Feedback (OFB). ECB encrypts each block independently, CBC encrypts blocks chained together with previous ciphertext, CFB and OFB use ciphertext to encrypt plaintext block by block in a chained fashion, avoiding error propagation between blocks.

ESCC is a new tweakable narrow-block mode of operation for disk encryption that is an extension of the Substitution Cipher Chaining mode (SCC). Unlike SCC, ESCC is resistant to known attacks on SCC. ESCC uses a tweak, sector ID, and expanded key to encrypt each 512-byte sector separately. It propagates errors to further blocks for added security. The designers claim ESCC provides security comparable to encrypting each block with a unique key while maintaining performance comparable to or better than existing disk encryption modes.
Information and data security block cipher and the data encryption standard (...
Block ciphers like DES encrypt data in fixed-size blocks and use symmetric encryption keys. DES is a 64-bit block cipher that uses a 56-bit key. It employs a Feistel network structure with 16 rounds to provide diffusion and confusion of the plaintext block. Each round uses subkey-dependent substitution boxes and permutation functions. While DES was widely adopted, cryptanalysis techniques showed it could be broken with less than 256 tries, making the key size too short by modern standards.

Modern symmetric cipher
This document discusses modern symmetric key algorithms. It describes stream ciphers and block ciphers, with RC4 and DES provided as examples. The concepts of confusion and diffusion are introduced. Modes of operation for block ciphers are defined, including ECB, CBC, CFB and OFB. DES encryption uses a 64-bit block size and 56-bit key, operating over 16 rounds of feistel network and key schedule. AES was selected to replace DES due to larger block size and key size, operating over 10 to 14 rounds of byte substitution, row shifting, column mixing and subkey addition. Symmetric key ciphers are fast but require secure key exchange and management to prevent repetition.
Network Security Lec4
The document discusses the Data Encryption Standard (DES) and its encryption process. It then summarizes the Rijndael cipher, which was selected as the Advanced Encryption Standard (AES) in 2001. The AES uses a block cipher structure of iterative rounds involving byte substitution, shifting rows of bytes, mixing columns of bytes, and adding round keys.
Block Ciphers Modes of Operation
The document discusses several modes of operation for block ciphers and stream ciphers. It explains that block cipher modes like CBC, CFB, OFB, and Counter Mode require an initialization vector (IV) to provide randomization and prevent identical plaintext blocks from encrypting to the same ciphertext. The IV must be transmitted along with the ciphertext and never reused with the same key. Stream ciphers like RC4 generate a pseudorandom key stream that is XORed with plaintext bytes to produce ciphertext.
Narrow bicliquesppt
This document summarizes a 2012 paper that describes a cryptanalysis of the full 8-round IDEA block cipher using narrow bicliques. Narrow bicliques limit the length of a biclique to the number of rounds needed for full diffusion. The attack partitions the key into sets and uses meet-in-the-middle techniques to test keys by calculating a variable in both the forward and backward directions through the cipher. This technique allows mounting meet-in-the-middle attacks on more rounds of IDEA than was previously possible.
Comparative analysis on different DES model

It operates on 128-bit blocks and supports key sizes of 128, 192, or 256 bits. The AES algorithm consists of repeated rounds of substitutions, shifts, and XOR operations with a expanded key schedule. It was designed to improve upon DES by having stronger cryptography and being more computationally efficient.

Des lecture
This document provides an overview of the Data Encryption Standard (DES) algorithm. It describes how DES was adopted as a standard in 1977, uses a 64-bit block size and 56-bit key, and has been widely used for encryption. The document outlines the key components of DES, including the initial permutation, round structure using substitution boxes and key schedule, as well as the decryption process. It notes that while DES was controversial due to its 56-bit key size, it exhibits good diffusion properties. However, it has been shown to be vulnerable to brute force and timing attacks in recent years.

This document summarizes the key components of encryption and decryption algorithms:
1. Plaintext is the initial intelligible message that is input into the encryption algorithm. The encryption algorithm performs substitutions and transformations on the plaintext using a secret key.
2. The secret key is independently input along with the plaintext and determines the exact substitutions and transformations performed, resulting in different ciphertext outputs for the same plaintext with different keys.
3. Ciphertext is the encrypted output that is unintelligible without the key. Decryption runs the encryption algorithm in reverse, using the ciphertext and key to recover the original plaintext.

DES (Data Encryption Standard) pressentation
This document discusses data encryption methods. It defines encryption as hiding information so it can only be accessed by those with the key. There are two main types: symmetric encryption uses one key, while asymmetric encryption uses two different but related keys. Encryption works by scrambling data using techniques like transposition, which rearranges the order, and substitution, which replaces parts with other values. The document specifically describes the Data Encryption Standard (DES) algorithm and the public key cryptosystem, which introduced the innovative approach of using different keys for encryption and decryption.
Data encryption standard
The document discusses the Data Encryption Standard (DES), which is a symmetric-key block cipher published by the National Institute of Standards and Technology (NIST). DES uses an initial and final permutation on data blocks, along with 16 rounds of permutations called Feistel rounds to encrypt data. It also discusses approaches for encrypting data using DES, such as making the last round different by removing the swapper, and how triple DES with three keys provides more security than double or single DES.
THE UNIFIED OPERATION STRUCTURE FOR SYMMETRIC-KEY ALGORITHM
In Cloud Computing, information exchange frequently via the Internet and on-demand. Modern
Internet protocols support several modes of operation to keep up with varied environments and
provide the variant choice, such as SSL and IPSec support multi-mode. The different mode has
the different characters. For example: CFB/OFB can be design operating without padding with
bit size keystream output, CBC/CFB can self synchronize to avoid channel noise, and CFB/OFB
needs encryption module only. The main emphasis is placed on the problem of case by case
operation mode usage. We describe a structure for the analysis of the block operation mode
combination. This unified operation structure, called UOS, combines existing in common and
popular block modes of operation. UOS does multi-mode of operation with most existing
popular symmetric block ciphers and do not only consist of encryption mode such as ECB, CBC,
CFB and OFB, that provides confidentiality but also message authentication mode such as
CBC-MAC in cryptography. It provides low-resource hardware implementation, which is
proper to ubiquitous computing devices such as a sensor mote or an RFID tag. Our contribution
provides a common solution for multi-mode and this is very suitable for ubiquitous computing with several resources and environments. The study indicates a better well-organized structure for symmetric block ciphers so as to improve their application scenarios.

Block Cipher and its Design Principles
This document discusses block ciphers, including their definition, structure, design principles, and avalanche effect. A block cipher operates on fixed-length blocks of bits and uses a symmetric key. It encrypts bits in blocks rather than one by one. Block ciphers have advantages like high diffusion but are slower than stream ciphers. They are built using the Feistel cipher structure with a number of rounds and keys. Important design principles for block ciphers include the number of rounds, design of the round function, and key schedule algorithm. The avalanche effect causes a small input change to result in a significant output change.

ENCRYPTION MODES IDENTIFICATION OF BLOCK CIPHERS BASED ON MACHINE LEARNING
Encryption modes affect the security of block ciphers. This paper proposes a new approach for identifying encryption modes based on machine learning and feature engineering. In the conditions of random keys and initialization vectors, five encryption modes are used for identification. Each mode is encrypted by several block ciphers. By comparing with previous work, we have overcome the shortcomings and improved the accuracy of identification by about 30% to 40%. The experiments improve the existing results and can effectively help cryptanalysts recover the keys.

Cryptography in Blockchain
This document discusses cryptography in blockchain. It begins by introducing blockchain and cryptography separately. It then defines important cryptography terminology like encryption, decryption, cipher, and key. It describes the main types of cryptography as symmetric-key, asymmetric-key, and hash functions. It explains how blockchain uses asymmetric-key algorithms and hash functions. Hash functions are used to link blocks and maintain integrity. Cryptography provides benefits like the avalanche effect and uniqueness to blockchain. Finally, it discusses an application of cryptography in cryptocurrency, where public-private key pairs maintain user addresses and digital signatures approve transactions.
DEC algorithm
DES (Data Encryption Standard) is a symmetric block cipher that uses a 56-bit key. It works by encrypting data blocks through 16 rounds of substitution and transposition. DES has several modes of operation including ECB (Electronic Code Book), CBC (Cipher Block Chaining), CFB (Cipher Feedback), OFB (Output Feedback), and CTR (Counter Mode). ECB encrypts each block independently, revealing patterns, while CBC chains blocks together using an initialization vector to add randomness. CFB and OFB allow encrypting smaller amounts of data. CTR operates independently without chaining blocks.
Data Encryption Standard (DES)
- DES (Data Encryption Standard) is a symmetric block cipher algorithm that encrypts data in 64-bit blocks using a 56-bit key. It was the first encryption standard adopted by the U.S. government for protecting sensitive unclassified federal government information.
- DES works by performing 16 rounds of complex substitutions and permutations on each data block, encrypting it using the key. It has various modes of operation like ECB, CBC, CFB, OFB, and CTR that specify how it operates on data.
- In 1998, DES was broken using a brute force attack by the Electronic Frontier Foundation in just 3 days, showing the need for stronger algorithms like AES which replaced DES as the encryption standard

This document summarizes the key aspects of cryptanalysis and the Data Encryption Standard (DES) algorithm. It discusses the tasks of a cryptanalyst in breaking encryption systems and outlines the basic structure and operation of DES. DES encrypts 64-bit blocks using a 56-bit key and 16 rounds of encryption. Each round uses a 48-bit subkey and the Feistel network structure to provide diffusion and confusion. The document also notes concerns about the cryptographic strength of DES' 56-bit keys and 8 substitution boxes against attacks over time.

The demand of satellite communication, the security algorithms are to be designed in the board. The information from the satellite to the ground is required the data security with the cryptographic algorithms. Advanced encryption standard (AES) is one of the promising cryptographic algorithms for the terrestrial communication. In this paper, the encryption and decryption is mainly focused on the cipher block chaining (CBC) mode for achieving the high secured data transmission. For efficient data transmission, the AES algorithm is implemented by using CBC mode. The proposed work is designed by using RTL modeling and also the minimum numbers of logical elements are used for implementation.
Block Cipher and Operation Modes
Block cipher modes of operation describe how a block cipher can be used for encrypting messages larger than the cipher's block size. The document discusses the five main modes of operation - electronic codebook (ECB), cipher block chaining (CBC), cipher feedback (CFB), output feedback (OFB), and counter (CTR) mode. It provides details on how each mode works, including diagrams, as well as advantages and disadvantages of some of the modes.
Secured algorithm for gsm encryption & decryption
This document describes Tharindu Weerasinghe's MSc research project on developing a hybrid cipher by combining a block cipher and a stream cipher. It summarizes the background on block ciphers like DES and stream ciphers like RC4. It then describes the researcher's algorithm that first encrypts plaintext using 3DES (a block cipher) and then RC4 (a stream cipher), and decrypts in the reverse order. The document discusses the benefits of combining ciphers and addresses some vulnerabilities of using block and stream ciphers individually. It also mentions the researcher implemented the algorithm in Java and measured encryption/decryption times.
Information and network security 18 modern techniques block ciphers
The block cipher processes fixed-size blocks simultaneously, as opposed to a stream cipher, which encrypts data one bit at a time. Most modern block ciphers are designed to encrypt data in fixed-size blocks of either 64 or 128 bits
Unit 2
The document discusses stream ciphers and block ciphers. It explains that stream ciphers encrypt data bit-by-bit or byte-by-byte, requiring a randomly generated keystream, while block ciphers encrypt fixed-length blocks, allowing for broader applications. It then focuses on the Feistel cipher structure for block ciphers, proposed by Feistel to approximate an ideal block cipher for large block sizes. The Feistel structure uses a product cipher approach involving substitutions and permutations to provide diffusion and confusion and resist statistical cryptanalysis.

Rass presentation
The document proposes a new symmetric key cryptographic algorithm called RASS that uses bitwise operations for encryption and decryption. Some key features include using two 16-bit keys to encrypt different parts of the plaintext concurrently via separate threads for improved security and performance. The algorithm uses both linear and "crisscross" XOR operations on 16-bit blocks. Performance analysis shows the algorithm has linear time complexity and outperforms previous similar bit-level algorithms.

Accident detection system project report.pdf
The Rapid growth of technology and infrastructure has made our lives easier. The
advent of technology has also increased the traffic hazards and the road accidents take place
frequently which causes huge loss of life and property because of the poor emergency facilities.
Many lives could have been saved if emergency service could get accident information and
reach in time. Our project will provide an optimum solution to this draw back. A piezo electric
sensor can be used as a crash or rollover detector of the vehicle during and after a crash. With
signals from a piezo electric sensor, a severe accident can be recognized. According to this
project when a vehicle meets with an accident immediately piezo electric sensor will detect the
signal or if a car rolls over. Then with the help of GSM module and GPS module, the location
will be sent to the emergency contact. Then after conforming the location necessary action will
be taken. If the person meets with a small accident or if there is no serious threat to anyone’s
life, then the alert message can be terminated by the driver by a switch provided in order to
avoid wasting the valuable time of the medical rescue team.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.
