摘要
数据加密标准DES是分组加密算法的代表,针对单DES的短密钥和双DES弱密钥等缺陷,论文重点对三重DES进行了研究。分析表明,3DES三次调用加密函数,由于其长密钥和复杂度的增加,抗攻击能力大大得到提升,加密信息的安全可靠得到保障。最后,面对日益强大的攻击,提出了DES未来发展的方向和设想。
Data encryption standard DES is the representative of packet encryption algorithm.Aiming at short key single DES and double DES weak keys and other defects,three DES is studied.Analysis shows that 3DES calls encryption fuction three times.Because of the increase in key length and complexity,anti attack ability is greatly improved,so that the encryption data is secuned.At last,the future development of DES is proposed.
