Authenticated Encryption;Block Ciphers;MAC Algorithms;Modes of Operation of a Block Cipher;Symmetric Cryptosystem Definition Galois Counter Mode (GCM) is a block cipher mode of operation that provides authenticated encryption with associated data. It has a minimal computational cost and is widely used ...
In this paper we introduce three developments of Counter Mode of Operation of Block cipher. These developments merge between advantages of Counter Mode with other Modes. This gives a good secure Modes for General purpose block-oriented transmission Authentication, Random access, Stream-oriented ...
In addition, when an application demands confidentiality and message integrity, theoverall efficiency of a security protocol can be improved by using the Authenticated Encryption (AE)block cipher mode of operation as compared to the conventional sequential encryption andauthentication. Amongst the AE ...
October 2012 328154-001 Enabling High-Performance Galois-Counter-Mode on Intel® Architecture Processors Executive Summary Galois-Counter Mode (GCM) is a block cipher mode of operation providing data security with AES encryption, and authentication with universal hashing over a binary field (GH...
In this mode, data is encrypted via Advanced Encryption Standard (AES) block cipher and an authentication tag is generated by applying a hash function (GHASH) to the entire ciphertext. This paper introduces novel techniques to further improve the performanc...
The hash subkey for the GHASH function is generated by applying the block cipher to the “zero" block. The pre-counter block (J0) is generated from the IV. In particular, when the length of the IV is 96 bits, then the padding string 031||1 is appended to the IV to form the pre...
A Block Cipher Mode of Operation with Two Keys In this paper, we propose a novel block cipher mode of operation (BCMO for short), named Output Protection Chain (OPC for short), which as a symmetric encr... YL Huang,FY Leu,JC Liu,... - Springer-Verlag 被引量: 5发表: 2013年 Coun...

This Recommendation specifies the Galois/Counter Mode (GCM), an algorithm for authenticated encryption with associated data, and its specialization, GMAC, for generating a message authentication code (MAC) on data that is not encrypted. GCM and GMAC are modes of operation for an underlying approved...
