Abstract
In ASIACRYPT 2016, Boyen and Li proposed an almost tightly secure short signature scheme based on pseudorandom function and the hardness assumption of short integer solution (SIS), and left it as an open problem to make it homomorphic. In this paper, we solve this problem with the same assumptions.
期刊介绍:
Theoretical Computer Science is mathematical and abstract in spirit, but it derives its motivation from practical and everyday computation. Its aim is to understand the nature of computation and, as a consequence of this understanding, provide more efficient methodologies. All papers introducing or studying mathematical, logic and formal concepts and methods are welcome, provided that their motivation is clearly drawn from the field of computing.
