GOST和BLOWFISH两种分组密码算法的重构

密码重构有助于增强安全性和构造新的算法,节约硬件资源和能源,延长设备使用周期。阐述了密码重构的概念及其重要性,并对国内外重构现状以及分组密码发展现状进行了研究。分别实现了GOST和BLOWFISH两种分组密码算法内的重构以及算法间的重构,给出了模块细化结果以及重构层次图。最后对后续进一步的研究和改进方向进行了阐述。

Reconstruction of GOST and BLOWFISH

Cipher reconstruction is helpful to enhance the security, construct new algorithms, save hardware resources and energy, extend equipment life-cycle. This paper describes the concept and importance of cipher reconstruction, studies the situation of reconstruction and block cipher both at home and abroad. The reconstructions of the individual algorithm itself and different algorithms of the module decomposed result and the reconstruction arrangement figure are given, GOST and BLOWFISH are realized, including ideas for future work.
