A Simpler Construction of CCA2-Secure Public-Key Encryption under General Assumptions
Abstract. In this paper we present a simpler construction of a publickey encryption scheme that achieves adaptive chosen ciphertext security (CCA2), assuming the existence of trapd...

Secure broadcasting in large networks
In this note, we show that a proposed secure broadcasting scheme is insecure. We also present a modified scheme to overcome this weakness. The modified scheme has the extra adva...

New Signature Schemes with Coupons and Tight Reduction
Amongst provably secure signature schemes, two distinct classes are of particular interest: the ones with tight reduction (e.g., RSA-PSS), and those which support the use of coupon...

An Extremely Small and Efficient Identification Scheme
We present a new identification scheme which is based on Legendre symbols modulo a certain hidden prime and which is naturally suited for low power, low memory applications. 1 Ove...
