Multisignature on Isogenies of Elliptic Curves with Participant Masking and Authentication

Key Points

• The aim is to develop a secure multisignature scheme using isogenies between elliptic curves for postquantum applications.
• Analyzed existing protocols based on elliptic curve isogenies
• Proposed a novel multisignature scheme with participant authentication
• Evaluated the effectiveness and safety of the scheme
• Demonstrated improved security features compared to traditional methods
• Proved the feasibility of participant authentication in the scheme
• Showed that the proposed method withstands potential quantum attacks
