| Abstract: | This paper introduces the definition and classification of cryptography,and describes the state of cryptography algorithm.In study of hash function,the change of HMAC after MD5 and SHA-1 were decoded.In studying symmetric key cryptography algorithm,the character of AES are analyzed,and AES are compared with DES,3DES and IDEA.In studying dissymmetric key cryptography algorithm,the paper makes comparison among RSA,DSA and ElGamal and it explains ECC in detail.Finally,the paper views the development of cryptography algorithm in future. |
