In ProvSec 2008, Wu et al. constructed two server-aided verification signature (SAV-) schemes based on BLS signature. In this paper, we provide a new definition of the security of...
Abstract. We firstly proposed a new notion of short identity-based signature scheme. We argue that the identity-based environment is essential in some scenarios. The notion of sho...
Generalized signcryption which proposed by Han is a new cryptographic primitive which can work as an encryption scheme, a signature scheme or a signcryption scheme [5]. However,the...
The concept of universal designated verifier signatures was introduced by Steinfeld, Bull, Wang and Pieprzyk at Asiacrypt 2003. These signatures can be used as standard publicly ve...
We provide constructions of (m, 1)-programmable hash functions (PHFs) for m ≥ 2. Mimicking certain programmability properties of random oracles, PHFs can, e.g., be plugged into ...
