Practical Implementation of Ring-SIS/LWE Based Signature and IBE
[chapter]
2018
Lecture Notes in Computer Science
Lattice-based signature and Identity-Based Encryption are well-known cryptographic schemes, and having both efficient and provable secure schemes in the standard model is still a challenging task in light of the current NIST post-quantum competition. We address this problem in this paper by mixing standard IBE scheme, à la ABB (EUROCRYPT 2010) on Ring-SIS/LWE assumptions with the efficient trapdoor of Peikert and Micciancio (EUROCRYPT 2012) and we provide an efficient implementation. Our IBE
