Abstract
- In order to address the problem of low security or complex computation in most existing sequential multi-signature schemes, this paper proposed a new secure and efficient certificateless sequential multi-signature scheme. To prevent public key replacement attacks, the scheme hashed the signer's identity and part of public key as the partial private key of the signer. Signers verified the partial signatures generated in the signature stage with the specified signature order to ensure the order of signatures. Under the random oracle model, the scheme was proved to be unforgeable and immutable based on the difficulty of computing discrete logarithmic problems. In the signature and verification stage, the scheme mainly involved elliptic curve point multiplication without bilinear pair. Theoretical analysis and simulation experiments show that compared with similar schemes, the proposed scheme can improve the efficiency by up to 28%. [ABSTRACT FROM AUTHOR]
