适合CBTC系统无线信道加密算法
Cryptography algorithm for wireless channel of CBTC system
摘要
Abstract
As to the disadvantages of RC4 which was used for CBTC system, a new cryptography algorithm based on Montgomery-form ECC was brought forward.Compared with the traditional Montgomery elliptic curve, the improved algorithm would resume the value of y-coordinate with more security.In addition, compared with the traditional ECC, it has faster computing speed and can effectively resist the timing attack and energy attack.The new Montgomery-form ECC algorithm has accelerated current ECC encoding speed and would make great improvement to the implementation of ECC in CBTC and other wireless communication.关键词
