摘　　要：本文根据IC卡仪表系统的实际需求,提出了一种基于Rijndael算法的改进算法,并针对该改进算法的实现问题进行了深入的研究。通过使用动态密码对明文的修补,使其密文长度与明文长度相等。同时,本文基于可编程专用集成电路(ASIC)和VHDL语言,在对接口单元、控制单元、密钥调度模块和加/解密模块分析设计的基础上,给出了用现场可编程门阵列(FPGA)实现该改进算法的一种方案。According to the requirements of IC cards meter system,an ameliorated method based on Rijndael is put forward in this paper. And the realization of the ameliorated method was lucubrated. The ameliorated algorithm ensures the length of cipher text is equal to the length of plain text by patching it with dynamic cipher. At the same time, the ameliorated Rijndael algorithm hardware realization scheme using Application Specific Integrated Circuit （ASIC） and VHDL is put forward,based on the study of interface units, control units, key expansion units and encrypt/decrypt units.
