Abstract— Converting a secure group key agreement protocol into password-based setting is not a trivial task. The security of a password-based scheme hinges on preventing diction...
We study the problem of authentication based on a weak key in the information-theoretic setting. A key is weak if its min-entropy is an arbitrary small fraction of its bit length. ...
A comprehensive treatment of network security. Topics include remote access security, DMZ, firewalls, VPNs, PKI architecture, X.509 Public key infrastructure, web security, S-HTTP,...
Sybil attack is a harmful threat to sensor networks, in which a malicious node illegally forges an unbounded number of identities to defeat redundancy mechanisms. Digital certifi...
