CDAuth Protocol Improves Efficiency in Cross-Domain Authentication
Original title: Efficient cross-domain multi-factor authentication
CDAuth integrates pseudo-identity, attribute concealment, and biometric hiding to reduce storage and computational costs using multi-edge servers and native group operations.
A cross-domain multi-factor authentication protocol called CDAuth is proposed to address inflexibility, high storage and computational consumption in existing models. It employs a universally applicable multi-factor authentication approach with pseudo-identity, attribute concealment, and biometric hiding. Multi-edge servers store only the union of terminal attributes and a verification token per subdomain, significantly reducing storage consumption. Authentication information sets can be freely added or modified.
- Multi-edge servers store union of attributes and verification token per subdomain
- Replaces bilinear pairing operations with native group operations
- Resists common security attacks while being more efficient
- Authentication information sets freely addable or modifiable
From the original article
1 min read at arxiv.orgSecure cross-domain authentication is crucial for protecting information exchange across terminals in different security domains. However, existing cross-domain authentication models suffer from inflexibility, high storage and computational consumption. In response to these problems, a cross-domain multi-factor authentication protocol with improved efficiency (CDAuth) is proposed.
