Definition ∞ A Digital Signature Algorithm is a mathematical scheme employed to verify the authenticity and integrity of digital messages or documents. It enables the recipient of a digital message to confirm the sender’s identity and ascertain that the message has not been altered in transit. These algorithms are foundational to the security of blockchain transactions and cryptographic communications. They rely on public-key cryptography to create and verify signatures.
Context ∞ The reliability of digital signature algorithms is paramount for securing digital assets and transactions across all blockchain networks. With the emergence of quantum computing, there is a pressing concern regarding the future vulnerability of current cryptographic standards. Consequently, significant research and development efforts are directed toward the creation and standardization of quantum-resistant algorithms to safeguard future digital security.
