Cryptography Algorithms are the foundation of information security.This paper introduces the mathematical definition of cryptography,and makes a comparison of symmetric cryptography algorithms and asymmetric cryptography algorithms,then analyzes the symmetric cryptography algorithms:DES,AES and the asymmetric cryptography algorithms:RSA,ECC and RTRU.AES is better than DES in security,efficiency and flexibility,and NTRU is better than RSA and ECC in security.
