Abstract

The invention provides a verifiable security outsourcing calculation method and system for an identification cryptosystem, and for a part needing outsourcing, Internet of Things terminal equipment firstly splits confidential parameters involved in each step, and then sends the encrypted parameters and some public parameters to two servers for calculation. And after the two servers complete corresponding calculation, the calculation results are returned to the Internet of Things terminal equipment, and the Internet of Things terminal equipment verifies the correctness of the returned results by using the verification information generated in the splitting process. And if the verification is passed, the Internet of Things terminal device carries out calculation to obtain a real calculation result. The method can be used for outsourcing calculation of algorithms such as identification-based data encryption, digital signature and signcryption, and the operation time of the Internet of Things terminal equipment can be saved.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to a verifiable and secure outsourcing calculation method and system for identifying a cryptographic system. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] With the cross-integration and mutual promotion of big data and Internet of Things technology, massive terminal devices in the Internet of Things, as an important means of data collection, continuously generate a large amount of data and upload it to the data center, forming a network infrastructure for the interconnection of everything and data circulation . Among them, security issues such as device identity authentication of massive IoT terminals and transmission encryption of confidential and sensitive data are becoming more and more important. [0004] The ident...
