The Study and Practice of the New Secret Code AES
Chen A-lin · 2004
AES is a new Encryption standard,NIST has select Rijndael as the Advance Encryption standard from five Candidate algorithms at 2000.Rijndael is a block cipher,it supports a block size of 128 bits and key sizes of 128、192、256 bits and named as AES-128,AES-192,AES-256.This paper introduce five Candidate algorithms and introduce Rijndael from its encryption priciple,encryption process,function definition,key expansion process,decryption process,practice process.
