CLEFIA算法的研究与改进
Research and Improvement of CLEFIA
摘要
Abstract
The CLEFIA is one of the two international standardized lightweight block cipher,which has important application value under the condition of resource constrain.In view of the problems that CLEFIA-128 need 5 round to realize the avalanche effect,and the diffu-sion effect is not obvious,and the design of round function in each round makes the efficiency of software and hardware lower,the CLE-FIA-128 is improved from the structure and round function.The test demonstrates the improved algorithm only need 4 rounds to realize the avalanche effect,its DC,LC and IDC indicates that the security is improved,while the software and hardware performance also increa-ses a lot.关键词
