TESLA: Tightly-Secure Efficient Signatures from Standard Lattices
signature scheme lattice cryptography tight security
2015/12/24
Generally, lattice-based cryptographic primitives offer good performance and
allow for strong security reductions. However, the most efficient current lattice-based signature
schemes sacrifice (part...
A Framework for Efficient Signatures，Ring Signatures and Identity Based Encryption in the Standard Model
Framework Efficient Signatures Ring Signatures Identity Based Encryption Standard Model
2010/3/16
In this work, we present a generic framework for constructing e±cient signature scheme, ring
signature schemes, and identity based encryption schemes, all in the standard model (without
relying on r...
