主 题：Homomorphic signature proxy signature security model provable security unforgeability
摘 要：The mushroom growth of IoT has been accompanied by the generation of massive amounts of *** to the limited storage and computing capabilities ofmost IoT devices,a growing number of institutions and organizations outsource their data computing tasks to cloud servers to obtain efficient and accurate computation while avoiding the cost of local data *** of the most important challenges facing outsourcing computing is how to ensure the correctness of computation *** homomorphic proxy signature(LHPS)is a desirable solution to ensure the reliability of outsourcing computing in the case of authorized signing *** has the characteristics of tamper-proof and traceability,and is a new technology to solve data ***,as far as we know,constructions of LHPS have been few and far *** addition,the existing LHPS scheme does not focus on homomorphic unforgeability and does not use blockchain ***,we improve the security model of the LHPS scheme,and the usual existential forgery and homomorphic existential forgery of two types of adversaries are *** the new model,we present a blockchain-based LHPS *** security analysis shows that under the adaptive chosen message attack,the unforgeability of the proposed scheme can be reduced to the CDH hard assumption,while achieving the usual and homomorphic existential ***,comparedwith the previous LHPS scheme,the performance analysis shows that our scheme has the same key size and comparable computational overhead,but has higher security.
