基于Twofish算法的标书加解密研究
Research on Encrypt and Decrypt of Bid Documents Based on Twofish
【摘要】 详细探讨了Twofish算法的加解密过程,分析了Twofish的特点和性能。通过对Twofish算法原理的研究来实现电子标书的安全保护。给出了实现其加解密算法的主要Java程序模块。同时,根据电子标书的特殊性,用基于公钥基础结构的技术实现了电子标书的混合加解密实现,并通过了程序测试。
【Abstract】 This paper discussed the procedure of encrypt and decrypt about Twofish algorithm particularly and analyzed the characteristics and performance of Twofish. Through researching the principle of Twofish, it implemented the security protection to digital bid and offers the main Java program about the encrypt and decrypt with Twofish algorithm. The program realized the encrypt and decrypt of digital bid documents based on PKI technology and passed the test.
