Description

Heterogeneous aggregation signature system applied to signature terminal
Technical Field
The invention relates to the technical field of information security data processing, in particular to a heterogeneous aggregation signature system applied to a signature terminal.
Background
Aggregate signatures are an important way of signing cryptography. An aggregate signature protocol allows any number of users to send their respective digital signatures to the same verifier over a public, unsecured channel. The verifier can aggregate the signatures of any plurality of users, and can verify whether the signatures of all the users are legal or not only by carrying out a signature verification algorithm once, and the aggregated signature can greatly improve the signature verification efficiency.
The existing public key cryptosystem is divided into three types: 1. the public key system based on the certificate adopts a certificate mechanism to realize the secure correspondence between the identity of the user and the key of the user, and generally adopts public key infrastructure (Public Key Infrastructure: PKI) technology. 2. An Identity-based public key system (Identity-Based Cryptography: IBC) in which the private key of the user is computationally generated by a trusted third party (key generation center: KGC) in the system using an Identity private key generation algorithm; 3. based on a public key hierarchy (Certificateless Public Key Cryptography, CLC) without certificates, the user private key in this mechanism is determined by two secret factors: one is a key related to the identity of the user extracted from the key generation center, and the other is a key generated by the user himself. From one secret element the other cannot be calculated, i.e. the key generation center cannot calculate the partial key of the user nor the partial key generated by the key generation center. Thus, the certificateless cryptographic system has no key escrow (key escrow) function.
If all participants of the cryptographic protocol belong to the same cryptographic system, the protocol belongs to an isomorphic cryptographic protocol. Otherwise, the protocol belongs to a heterogeneous cryptographic protocol.
Currently, an aggregate signature protocol based on an isomorphic cryptographic protocol is mature, and mainly comprises the following steps:
in 2008, wen and Ma [ y.wen, j.ma, an aggregate signature scheme with constant pairing operations,2008 International Conference on Computer Science and Software Engineering,2008,pp.830-833 ] proposed an aggregate signature protocol that only required a fixed number of bilinear pairs. This protocol allows any number of PKI users to sign, and the verifier can aggregate and verify all users' signatures at once. But this method is only applicable to PKI.
In 2019, yang et al [ X.Yang, R.Liu, M.Wang and G.Chen, identity-based aggregate signature scheme in vehicle ad-hoc network,2019 4th International Conference on Mechanical,Control and Computer Engineering,2019,pp.1046-1049 ] proposed an aggregate signature protocol suitable for Internet of vehicles. The protocol allows users of any multiple IBCs to sign, and a verifier can aggregate and verify the signatures of all users at once. But this method is only applicable to IBC.
2021, kar et al [ J.Kar, X.Liu and F.Li, CL-ASS: an efficient and low-cost certificateless aggregate signature scheme for wireless sensor networks, journal of Information Security and Applications,2021,61, p.102905 ] proposed an aggregate signature protocol suitable for wireless sensor networks. The protocol allows users of any multiple CLCs to sign, and the verifier can aggregate and verify the signatures of all users at once. But this method is only applicable to CLCs.
