Constructing Committed Signatures from Strong-RSA Assumption in the Standard Complexity Model
In this paper, we provide the first committed signature provably secure in the standard complexity model based on the strong RSA assumption. The idea behind the construction is that given any valid partial sig...

Augmented Oblivious Polynomial Evaluation Protocol and Its Applications
In this paper, we first introduce a new notion called augmented oblivious polynomial evaluation (AOPE), a useful notion to deal with the general oblivious polynomial evaluation protocol. And then we propose a ...

Sequential Aggregate Signatures Working over Independent Homomorphic Trapdoor One-Way Permutation Domains
The contribution of this paper has two folds. In the first fold, we propose a generic construction of sequential aggregate signatures from families of certificated trapdoor one-way permutations. We show that o...

Computing of Trust in Ad-Hoc Networks
Although, the notion of trust has been considered as a primitive for establishing relationships among nodes in ad-hoc networks, syntax and metrics of trust are not well defined. This paper studies computing of...

Multi-party Stand-Alone and Setup-Free Verifiably Committed Signatures
In this paper, we first demonstrate a gap between the security of verifiably committed signatures in the two-party setting and the security of verifiably committed signatures in the multi-party setting. We the...
