An Efficient Identity-based Multi-signcryption in Standard Model
摘要
Abstract
Signcryption can achieve encryption and signature at the same time,and less computational complexity than the traditional se-cure schemes that fulfill the functions both. Therefore it becomes one of the hottest topics in today’ s cryptography to construct a secure and efficient Identity-Based Signature ( IBS) under standard model. In the IBS,identity-based encryption algorithm and multi-receiver signature algorithm are combined with bilinear pairing on elliptic curves to establish the structure and security concept of ID-based sign-cryption scheme for multiple receivers,forming an efficient identity-based multi signcryption. In view of the low efficiency of existing i-dentity-based multi-signcryption,an efficient identity-based multi-signcryption algorithm is proposed,and it reduces the amount of power operation when the number of the signcrypter is n(n > 1) and gives the security and efficiency analysis in the standard model. It has proved that the new scheme’ s secure under CDH assumption and reduces the calculation. Compared with the original scheme,the signcryption efficiency has been significantly improved.关键词
