一种基于身份的服务器辅助验证签密方案
An ID-based Server-aided Verification Signcryption Scheme
摘要
Abstract
In order to improve the efficiency of the existing ID-based signcryption algorithm,taking into consideration the characteristic of low computing power of low-end devices,introducing the idea of server-aided verification,this paper presents a server-aided verification signcryption scheme.Complex operations in the verification process are carried out through the server,which effectively reduces the amount of computation and running time in the validation phase of the algorithm,and makes the application of the algorithm in the low-end device possible.Based on the difficult hypothesis of Decision Bilinear Diffie-Hellman(DBDH)problem and Calculation of Diffie-Hellman(CDH)problem,it proves the scheme meets the unforgeability and confidentiality in random oracle model.关键词
