边缘计算环境下的轻量级聚合无证书签密方案
Lightweight aggregated certificateless signcryption solution for edge computing environments
摘要
Abstract
Edge computing involves a large number of device nodes,which raises the risk of data leakage,and edge devices have limited computational and storage resources and low computational efficiency to handle complex computational tasks.To address these problems,a lightweight aggregated certificateless signcryption is proposed.Scalar point multiplication on elliptic curves is utilized instead of bilinear pair operation,and a shorter key is used to achieve stronger security and reduce storage and transmission overhead,while the tamper-proof property of the blockchain is utilized to ensure the confidentiality,authenticity of data,as well as the integrity and authenticity of all transaction data.In addition,under the assumption of elliptic curve discrete logarithmic difficulty problem(ECDLP)and elliptic curve Diffie-Hellman difficulty problem,it is proved that the scheme satisfies the unforgeability and indistinguishability.Theoretical analysis and experimental results show that the scheme has obvious advantages over other schemes in terms of security and communication efficiency.关键词
