Unforgeability is a critical security property of digital signatures or cryptographic proofs, guaranteeing that an unauthorized entity cannot produce a valid signature or proof without access to the legitimate secret key. This ensures the authenticity and integrity of digital information. It is fundamental to preventing fraudulent activities.
Context
This property is fundamental to the security of all blockchain transactions and digital asset ownership. News often discusses unforgeability in the context of cryptographic attacks, protocol upgrades, or the development of new signature schemes designed to maintain this essential security characteristic against evolving threats. Its robustness is paramount for trust.
