Passive Attack on RFID LMAP++ Authentication Protocolly logical operator XOR and modular 2. addition. In this paper, a passive attack on LMAP++ protocol is given after constructing the distinguisher for the random numbers used in the protocol. The attack shows the protocol cannot resist passive attack, and after eavesdropping about 480 authentication

AniCAP: An Animated 3D CAPTCHA Scheme Based on Motion Parallaxmes have been proposed and deployed on various websites to secure online services from abuse by automated programs. However, many of these CAPTCHAs have been found to suffer from design flaws that can be exploited to break the CAPTCHA. Hence, the development of a good CAPTCHA scheme that is both sec
