对一个分组密码设置密钥的最常用方法是使用一个主密钥。然后再使用一种密钥衍生算法(key derivation algorithm),例如PKCS#5,衍生出一个密钥和一个IV(或Counter)。 密钥衍生函数(Key Derivation Function, KDF)从其他的熵源衍生出密钥,同时会保留输入的熵而且是单向的。密钥衍生不仅仅是常用于生成密钥,它也用于衍生IV...

Key pipeliningSearch Based MemoryVLSIA high speed security algorithm is always important for wired/wireless environment. The symmetric block cipher plays a major role in the bulk data encryption. One of the best existing symmetric security algorithms to provide data security is AES. AES has the ...
To summarize, an important part of AES encryption and decryption is the generation of multiple round keys from the initial seed key. This KeyExpansion algorithm generates a key schedule and uses substitution and permutation in a way that is similar in most respects to the encryption and decryption...
