It is well-known that CA plays the central role in PKI. In this paper we introduce a new component into PKI, DA (decryption authority), which decrypts important and sensitive mess...
The Double Authentication (DA) scheme presented in [1] is designed to provide security against impersonation attack to link state routing protocol at a lower computational cost as...
A basic function of all signatures, digital or not, is to express trust and authority, explicit or implied. This is especially the case with digital signatures used in certificates...
Abstract. We propose a flexible method for verifying the security of ML programs that use cryptography and recursive data structures. Our main applications are X.509 certificate ch...
Assuming a cryptographically strong cyclic group G of prime order q and a random hash function H, we show that ElGamal encryption with an added Schnorr signature is secure against ...
