Abstract. Existing navigation services, such as GPS, offer no signalintegrity (anti-spoof) protection for the general public, especially not with systems for remote attestation of...
The Wired Equivalent Privacy (WEP) uses the 64 bit RC4 secret key stream cipher as its layer 2 security protocol. Although the underlying RC4 cipher is secure, the potential reuse...
The security of hash functions based on a block cipher with a block length of m bits and a key length of k bits, where k ≤ m, is considered. New attacks are presented on a large ...
We present the first hierarchical identity based encryption (HIBE) system that has full security for more than a constant number of levels. In all prior HIBE systems in the literat...
Abstract. Automated tools for finding attacks on flawed security protocols often struggle to deal with protocols for group key agreement. Systems designed for fixed 2 or 3 party pr...
