摘要
中国学者提出的演化密码作为密码学研究的一种新的方法,在分组密码、ECC公钥密码等密码设计和分析中取得重要进展。考虑到跳频通信中采用的密码算法设计使得跳频系统信号的安全性得到广泛关注,为改进目前跳频序列安全性,提出了一种基于演化DES的安全跳频序列设计方案,提高了抗差分攻击和线性攻击能力。通过对跳频序列的多项性能进行测试,测试结果表明跳频序列不仅通过了NIST测试,而且在安全性、均匀性、相关性、线性复杂性和随机性等方面获得了较大的改善。
In previous China Conference on Cryptographic Algorithm,several research progresses on designation and analysis of block cipher and ECC etc were introduced with a new method based on evolutionary cryptosystem.Considering a kind of anti-jamming technologies—frequency hopping(FH) communication that changes the signals frequencies depending on FH sequence,it is important to pay attentions to the security of FH sequence.In order to improve the security of FH sequence,this paper proposes a design of FH sequence based on evolutionary DES encryption algorithm and improves the ability of anti-differential attacks and anti-linear attacks.By doing some tests on the performances of FH sequence,the test results show that the FH sequence not only passes the NIST tests,but also gets a better performance in security,uniformity,correlation,linear complexity and randomness.
