Abstract

The fast expansion of information technology and public concern for personal privacy and security have raised expectations for the authentication process. Although existing anonymous authentication schemes can achieve anonymous authentication and accountability, they all require users to apply for certificates from the authorization authority, resulting in a significant certificate storage overhead for the authority. Additionally, they have not implemented certificate revocation for anonymous users, which allows malicious users to potentially engage in malicious behavior. Therefore, this paper proposes an efficient and revocable anonymous account guarantee system based on blockchain (ERAAS). The system implements a guarantor mechanism where anonymous users can authenticate their identities through the guarantees provided by guarantors without the need to apply for certificates, reducing the storage overhead of certificates. Furthermore, the system utilizes cryptographic accumulators to enable fast revocation of accounts, preventing malicious users from engaging in further malicious behavior. Moreover, in this system, the certificate authority (CA) can enhance the system’s ability to handle concurrent requests by allocating group keys to the registration authority (RA), authorizing them to register guarantors and sign guarantees. Security analysis indicates that the proposed scheme enjoys anonymity, traceability, and revocability and can resist forgery attacks. The experimental comparison demonstrates its practicality.
