摘要
针对网络虚拟财产的安全问题,提出了利用Hash函数和三元组生成加密表的思想,探讨了密码学上的Hash函数的选择方法,研究了基于分组密码CBC工作模式的Hash函数,提出了三元组的抗原像性概念,给出了三元组密码表的结构定义。利用Hash函数的不可逆特性和三元组的离散性,实现了基于Hash函数和三元组的密码表。实验结果及理论证明,该设计思想能够提供安全性较强的密码表,能够有效抵御恶意攻击。
The paper proposed the ideas of the password table based on hash function and triple, discussed the selection method of Hash function in cryptography, study the Hash function based on block cipher ＇ CBC mode, proposed the antigen concept of triple, given the structure of the triples password table defined. To Hash functions irreversible characteristics and triples discreteness, realized the password table based on hash function and triple. The experimental results and theoretical Prove that the design ideas can provide strong security password table, and can effectively defend against malicious attacks.
