In this paper, we propose an MQ-based 3-pass IDS with impersonation probability of 1/2 and apply the original version of the Unruh transform to it.

Abstract: At PKC 2018, Chen et al. proposed SOFIA, the first MQ-based digital signature scheme secure in the quantum random oracle model (QROM).

At PKC 2018, Chen et al. proposed SOFIA, the first MQ-based digital signature scheme having tight security in the quantum random oracle model (QROM).

At PKC 2018, Chen et al. proposed SOFIA, the first MQ-based digital signature scheme secure in the quantum random oracle model (QROM).

It shortens the data and associated signatures to reduce the bandwidth requirement. The compact aggregate signature (CAS) scheme creates a constant length�...

Abstract. We propose SOFIA, the first MQ-based signature scheme provably secure in the quantum-accessible random oracle model (QROM).

The signature size of the digital signature scheme decreases by about 35% compared with SOFIA in the level I of NIST PQC security category, and is supposed�...

At PKC 2018, Chen et al. proposed SOFIA, the first MQ-based digital signature scheme having tight security in the quantum random oracle model (QROM).

Recently, Beullens [1] proposed a MQ-based DSS constructed from the Fiat-. Shamir transform, called MUDFISH, which is proven to be EU-CMA secure in the QROM and�...
