AN EFFICIENT IDENTITY-BASED IDENTIFICATION PROTOCOL FROM LATTICES
摘要
Abstract
Identity-based identification protocol is one of the most important applications of cryptography.It is an important research direction to ensure the security and efficiency of this primitive in post-quantum era.In this paper,in order to make up for the shortcomings of the current quantum-based security protocols such as identity-based identification protocols,which are inefficient and have a large gap with the actual application requirements, parameter optimization techniques such as dual commitments and responses were adopted to improve the identification.An identity-based identification from lattice assumptions in the standard model was proposed.Based on the Ideal-SVP problem,this scheme proved the security under the imitator's static identity and concurrent active attack model.Compared with the existing programs,the program's space efficiency and computing efficiency has been improved.关键词
