Abstract. Certificateless cryptography introduced by Al-Riyami and Paterson eliminates the key escrow problem inherent in identity based cryptosystems. Even though building practic...

On-Line Authenticated Encryption (OAE) combines confidentiality with data integrity and is on-line computable. Most block cipher-based schemes for Authenticated Encryption can be ...
In this paper, we propose a new approach for constructing selectively convertible undeniable signature schemes, and present two efficient schemes based on RSA. Our approach allows ...
We answer the open question of the possibility of building a digital signature scheme with proven security based on the one-wayness of a trapdoor permutation and with signatures as...
Fail-stop signature (FSS) schemes are important primitives because in a fail-stop signature scheme the signer is protected against unlimited powerful adversaries as follows: Even i...
