Lee and Lee recently pointed out that the Hsu et al. authenticated key agreement scheme is vulnerable to the modification attack and further proposed an improvement of Hsu et al. However, this work shows that Lee and Lee scheme is vulnerable to the man-in-the-middle attack. A slight improvement to their scheme is proposed to overcome this weakness. 2005(More)
This paper presents a partitioned systolic array with an arbitrary number of PEs for MSB-first approach multiplication in GF(2) based on the polynomial representation. As compared to the related multipliers presented by Wang et al. the proposed partitioned systolic array requires significantly small number of basic cells. It requires only m/2 number of(More)
