A malicious security model is a cryptographic framework that assumes participants in a protocol may act arbitrarily and attempt to subvert the system’s security properties. This model considers the strongest possible adversarial behavior, where attackers can deviate from protocol specifications in any way they choose. Protocols designed under this model offer robust security guarantees.
Context
Protocols designed under a malicious security model are highly valued in decentralized finance and blockchain for their resilience against sophisticated attacks. News often highlights audits or analyses that confirm a system’s security under such stringent assumptions, building user confidence. The continuous challenge involves designing systems that remain efficient while providing strong security guarantees against highly capable adversaries.
