1. 什么是cipher-based message authentication code(基于密码的消息认证码)? 基于密码的消息认证码(Cipher-based Message Authentication Code,简称CMAC)是一种使用对称加密算法来生成消息认证码(MAC)的技术。它确保了消息的完整性和认证,即接收方可以验证消息在传输过程中是否被篡改,并且确认消
SPACE is a table-based cryptographic primitive whose table comprises the pairs of inputs to a block cipher such as AES and the corresponding outputs. In line with SPACE, other whitebox cryptographic schemes were proposed and offer sufficient security as SPACE does. However, there is still room ...

In Section 5, the stream cipher system based on the ADHC model and parameter-varying 3D Logistic map is proposed. Security and performance analyses are also conducted. Finally, conclusion remarks follow in Section 6. Access through your organization Check access to the full text by signing in ...
Preneel et al. (Crypto 1993) assessed 64 possible ways to construct a compression functions out of a blockcipher. They conjectured that 12 out of these 64 so-called PGV constructions achieve optimal security bounds for collision resistance and preimage..
The cipher relies on simple operations (exclusive-OR) that can be efficiently realized on a standard computer. Lian et al. (2005) proposed another block cipher based on the chaotic standard map which has three parts: the key generator, diffusion function and confusion based on the standard map...
