Cryptographic Standards

Definition ∞ Cryptographic standards are established specifications and protocols that govern the secure creation, management, and use of cryptographic algorithms. These standards ensure the integrity, confidentiality, and authenticity of digital information and transactions. They are fundamental to the security of blockchain networks and digital assets. Adherence to these standards is critical for preventing security vulnerabilities.
Context ∞ Cryptographic standards are foundational to the security and trustworthiness of all digital assets and blockchain systems. News in this area often covers advancements in cryptographic techniques, such as post-quantum cryptography, or the discovery of vulnerabilities in existing standards. Debates sometimes arise regarding the adoption of new algorithms or the deprecation of older, less secure ones. Maintaining robust cryptographic standards is essential for the long-term viability and security of the digital economy.
