Chaining & counter-based block cipher mode for authentication
摘要
Abstract
For raising the operation efficiency of block cipher algorithms, a fast authentication mode based on chaining & counter (CCTR) was put forward; and its security was proved. Its speed was about 30% faster than that of authentication modes in common use (for example, CBC-MAC). The dependence test results accord with the demands. The CCTR mode is complete; its degree of avalanche effect is about 0.999 3; its degree of strict avalanche criterion is 0.992 or so.The frequency test results indicate that the output generated by the CCTR mode had uniformity. The binary matrix rank, Run, spectral, non-overlapping template matching, overlapping template matching, Maurer's universal statistical test,Lempel-Ziv compression, linear complexity, serial, approximate entropy, cumulative sums, random excursions and ran-dom excursions variant tests results fulfilled the requirements all. Therefore, the CCTR mode has good pseudo-random-ness, which the security of CCTR mode is verified by way of statistical evaluation.关键词
