The Boyen-Li signature scheme [Asiacrypt'16] is a major theoretical breakthrough. Via a clever homomorphic evaluation of a pseudorandom function over their verification key, they achieve a reduction l...
Driven by the open problem raised by Hofheinz and Kiltz (Journal of Cryptology, 2012), we study the formalization of lattice-based programmable hash function (PHF), and give two types of constructions...
Designing efficient signature scheme based on the standard assumption such as the Computational Diffie-Hellman (CDH) assumption is important both from a practical and a theoretical point of view. Cu...
We present a lattice-based stateless signature scheme provably secure in the standard model. Our scheme has a constant number of matrices in the public key and a single lattice vector (plus a tag) in...
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 the generic constructi...

We describe a short signature scheme which is existentially unforgeable under a chosen message attack without using random oracles. The security of our scheme depends on a new complexity assumption ...
The object of this paper is the concrete security of recent multivariate signature schemes. A major challenge is to reconcile some ”tricky” ad-hoc constructions that allow to make short signatures, ...
We construct three new signatures and prove their securities without random oracles. They are motivated, respectively, by Boneh and Boyen [9]’s, Zhang, et al. [45]’s, and Camenisch and Lysyanskaya [1...
With computer networks spreading into a variety of new environments, the need to authenticate and secure communication grows. Many of these new environments have particular requirements on the appli...
