block cipher scheme

基本解释

A natural problem is that could one apply for a fast hash scheme to construct a cipher block algorithm.
一个自然的问题是能否利用快速安全的杂凑算法构造相应的分组加密算法呢?。
A novel scheme based on traditional electronic codebook(ECB) mode was proposed to improve the capability of block-cipher mode of operation.
为提高分组密码工作模式的性能，提出了1个基于电码本（ECB）模式的新方案。
Investigation shows that the scheme is provable security under the blockwise adaptive attack model if the underlying block cipher is a pseudorandom permutation.
结果表明，在所用分组密码是伪随机置换的条件下，方案在分块适应性攻击模型下是可证明安全的。

分组密码
Chaotic block cipher scheme: this scheme combines spatiotemporal chaos and blowfish arithmetic together. The P and S-box are generated using on two-way coupled map lattice system, without depending on blowfish cycles.
混沌分组密码加密方案:将时空混沌和blowfish算法相结合,使用双向耦合映象格子产生blowfish算法所需的子密钥数组P和S盒子,P和S的产生不依赖于blowfish的循环迭代。
