We introduce and analyze a randomized traitor tracing algorithm for broadcast security. This algorithm is very efficient compared to brute force methods (the mean time it takes is...
When the network is homogeneous, choosing the cipher type for a packet telephony application is simple. It is clear that stream ciphers perform better than block ciphers over land...
Tagging schemes have been used in security protocols to ensure that the analysis of such protocols can work with messages of bounded length. When the set of nonces is bounded, this...
Abstract. Radio Frequency Identification (RFID) systems are vulnerable to relay attacks (i.e., mafia, terrorist and distance frauds) when they are used for authentication purpose...
