Digital Signature Algorithms

Definition ∞ Digital Signature Algorithms are cryptographic methods used to verify the authenticity and integrity of digital data. These mathematical procedures ensure that a digital message originates from a specific sender and remains unaltered since its signing. They are essential for securing transactions, authenticating users, and establishing trust in decentralized systems like blockchains. Examples include ECDSA and RSA, which underpin much of current digital security.
Context ∞ The ongoing security of digital assets and blockchain systems relies heavily on the strength of digital signature algorithms. A primary concern currently centers on the threat posed by quantum computers, which could potentially compromise existing algorithms. Consequently, the development and adoption of quantum-resistant algorithms represent a critical area of focus for maintaining long-term cryptographic security across the digital landscape.
