Combined Implementation Attack Resistant Exponentiation
Different types of implementation attacks, like those based on side channel leakage and active fault injection, are often considered as separate threats. Countermeasures are, there...

Starfish on Strike
This paper improves the price-performance ratio of ECM, the elliptic-curve method of integer factorization. In particular, this paper constructs "a = -1" twisted Edwards ...

Broadcast Encryption with Multiple Trust Authorities
Abstract. In this paper we extend the notion of hierarchical identitybased encryption with wildcards (WIBE) from the domain of a single Trusted Authority (TA) to a setting with mul...

Cryptanalysis of the Hidden Matrix Cryptosystem
Abstract. In this paper, we present an efficient cryptanalysis of the socalled HM cryptosystem which was published at Asiacrypt’1999, and one perturbed version of HM. Until now, ...

On the Round Complexity of Zero-Knowledge Proofs Based on One-Way Permutations
We consider the following problem: can we construct constant-round zero-knowledge proofs (with negligible soundness) for NP assuming only the existence of one-way permutations? We...

Message Recovery and Pseudo-preimage Attacks on the Compression Function of Hamsi-256
Hamsi is one of the second round candidates of the SHA-3 competition. In this study, we present non-random differential properties for the compression function of the hash functio...

How Leaky Is an Extractor?
This paper discusses the security of a leakage-resilient stream cipher presented at FOCS 2008, instantiated in a practical setting. Based on a case study, we put forward implementa...

A Lattice-Based Threshold Ring Signature Scheme
In this article, we propose a new lattice-based threshold ring signature scheme, modifying Aguilar’s code-based solution to use the short integer solution (SIS) problem as securi...
