| 摘 要： | 密码算法是信息安全的重要保证。介绍了密码体制的数学定义,并比较了对称密码算法和非对称密码算法,比较了DES、AES对称密码算法,两者中AES具有比DES更好的安全性、效率、灵活性;分析比较了RSA、ECC、NTRU等非对称密码算法,要实现相同的安全水平NTRU所需要密钥长度最短。

| Abstract: | 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. |
