A secure distributed resolution model for industrial internet identifier based on ordered multi-group signature

Abstract

The security of the industrial Internet identifier resolution system is critical to ensuring the circulation of data in industrial production. Most existing schemes mainly use blockchain to solve problems such as a single point of failure and the unfair interests of multiple parties in the identifier resolution system. However, these schemes usually ignore the security of source data and transmission of the identifiers, which makes the identifiers vulnerable to manipulation or privacy disclosure. To address these issues, we propose a secure distributed resolution model for industrial Internet identifier based on ordered multi-group signature named SDRMI-OMGS. Specifically, a novel resolution model for industrial Internet identifier is proposed for enhancing the security of the identifiers in SDRMI-OMGS, which includes the Ordered Multi-Group Signature (OMGS) and the improved identifier encoding scheme. We conceive an authentication mechanism with OMGS to achieve trusted authentication of the identifiers and users during identifier resolution. Moreover, we utilize the confidentiality of asymmetric encryption and the immutability of blockchain to implement an identifier encoding scheme, which prevents the identifiers from manipulation or privacy disclosure during transmission. Finally, we prove the security of OMGS in SDRMI-OMGS based on the assumption of the hardness of the Elliptic Curve Discrete Logarithm Problem (ECDLP). Through experiments on the group signature, compared with the baselines, the extensive results show that the signature efficiency and verification of our scheme are increased by 67%, 40%, 58%, 35%, respectively in case of different members and groups.
