A Certificateless Aggregate Signcryption Scheme without Bilinear Pairing
摘要
Abstract
Certificateless aggregate signcryption scheme can aggregate different signcryptions generated by multi-users corresponding to various information into one signcryption,which can not only ensure the confidentiality and certification in information transmission but also reduce power dissipation.Therefore,it is applied in the multiple-to-single mode in large-scale distributed communication.Most aggregate signcryption schemes need computation of bilinear pairing with poor efficiency.For that,an efficient certificateless aggregate signcryption schemes without bilinear pairing is proposed,where disperse logarithm is employed in random oracle model to improve the original aggregate signature algorithm without bilinear pairing for safer and more effective one.Based on the proposed aggregate signcryption security model,investigation and analysis on the presented scheme with random oracle model is performed and validation on its effectiveness and feasibility also conducted.Theoretical analysis shows that in the presence of multiple signcrypter it owns not only the confidentiality and unforgeability but also higher computational efficiency.关键词
