Message verification method, device and equipment and readable storage medium

Abstract

The invention discloses a message verification method. The method comprises the steps of obtaining a target message in a mobile internet; carrying out re-signature on the target message by utilizing apart of blind agent re-signature algorithm to obtain a target re-signature of the target message; verifying the target re-signature by using a server-assisted verification protocol; and if the targetre-signature passes the verification, marking that the target message passes the verification. After carrying out re-signature on a target message in the mobile internet by utilizing a part of blindagent re-signature algorithm, the target re-signature is verified by using the server-assisted verification protocol, so that the calculation amount and the calculation complexity of verifiers in partof blind agent re-signatures can be reduced, the part of blind agent re-signature scheme is suitable for terminals with low calculation capability in the mobile internet, and the message signature verification efficiency is also improved. Correspondingly, the message verification device and equipment and the readable storage medium provided by the invention also have the above technical effects.

Description

technical field [0001] The present application relates to the technical field of information security, in particular to a message verification method, device, equipment and readable storage medium. Background technique [0002] The signature verification step in the existing partial blind proxy re-signature scheme involves 4 bilinear pairing operations, which makes the verifier have a large amount of verification calculations and slow verification efficiency, thus slowing down the signature verification efficiency of the partial blind proxy re-signature scheme , increasing the computational complexity of the partial blind proxy re-signature scheme. [0003] It is precisely because the existing partial blind proxy re-signature scheme has a large amount of calculation and high computational complexity, and the computing power of each terminal in the mobile Internet is relatively low, so it cannot undertake the verification process of high complexity, so that the existing Some...
