We propose a zero-knowledge interactive proof based identification and signature scheme. The protocol is based on Euler's totient function and discrete logarithms over the ri...
The small subgroup confinement attack works by confining cryptographic operations within a small subgroup, in which exhaustive search is feasible. This attack is overt and hence ca...
Anonymity is a security property of paramount importance, as we move steadily towards a wired, online community. Its import touches upon subjects as different as eGovernance, eBusi...
pwdArmor is a framework for fortifying conventional password-based authentications. Many password protocols are performed within an encrypted tunnel (e.g., TLS) to prevent the exp...
The NRL Protocol Analyzer (NPA) is a tool for the formal specification and analysis of cryptographic protocols that has been used with great effect on a number of complex real-l...
