基于KLEIN密码的存储器加密技术

Storage Encryption Technology Based on KLEIN Cipher

针对日益严峻的智能卡芯片数据存储安全威胁以及当前常用存储器加密技术的不足等问题,提出了基于轻量级分组密码算法KLEIN的智能卡存储器加密方法,设计实现了KLEIN密码算法的IP核,并给出性能与安全性的分析.与传统方法相比,本文方法可以保证智能卡芯片高效运行、抗DPA攻击和安全存储.

Because of the growing threat to the storage security of smart card chip and shortage in present storage encryption method,we propose the storage encryption method of smart card based on light weight block cipher KLEIN.We have designed and realized the IP core of KLEIN cipher,and given the performance and security analysis.Compared with traditional methods,the method proposed in this paper can ensure efficient operation,anti-DPA attack and security storage of smart card.
