We present the first cryptographically sound security proof of the well-known Otway-Rees protocol. More precisely, we show that the protocol is secure against arbitrary active att...
Address harvesting is the act of searching a compromised host for the names and addresses of other targets to attack, such as occurs when an email virus locates target addresses f...

In 2004, Yoon et al. proposed a user authentication scheme based on generalized ElGamal signature scheme using smart cards. In their scheme, the previous session keys will be comp...
A sensitive point in public key cryptography is how to protect the private key. We outline a method of protecting private keys using cryptographic camouflage. Specifically, we do ...
The popularity of "Trust-on-first-use" (Tofu) authentication, used by SSH and HTTPS with self-signed certificates, demonstrates significant demand for host authenticatio...
