Modular multiplication is the fundamental operation in most public-key cryptosystem. Therefore, the efficiency of modular multiplication directly affects the efficiency of whole crypto-system. This paper presents implementation and comparison of several recently proposed, highly efficient architectures for modular multiplication on FPGAs: interleaved multiplication, two variants of Montgomery multiplication,...
This paper presents an improved algorithm for detecting the SYN flooding attacks. The algorithm is based on the characteristics of the network processor IXP2850's hardware and software framework. It improves the typical method that is based on checking the received SYN segments twice from the same source. The improved algorithm will label the segments first, and then verify them to determine whether...
In this paper, a new algorithm of dynamic display is introduced for design of the large LED screen, it employs the image masking technology for multi-scanning-beam displaying dynamically. In order to verify the effectiveness of our new algorithm, a LED display system is designed and implemented with the microcontroller of STC12C5A60S2. The result shows that this algorithm improves the performance...
