Abstract:

Web Services is becoming the prevailing next-generation framework of e-commerce. It is a challenging issue to ensure the security of Web Services. Rep lay attack is a kind of attack that severely threatens the security of network information. An approach named challenge/response mode has been proposed  to withstand it. This article proposes an improvement on the traditional challenge/response mode to improve its performance in Web Services environments  . The result shows that the improved solution can produce better performance while preserving the ability to withstand the replay attacks.

Key words: Web Services, replay attack, challenge response
