Cryptographic Principles

Definition ∞ Cryptographic principles are foundational mathematical concepts and techniques used to secure digital information and communications. These principles ensure data confidentiality, integrity, authenticity, and non-repudiation within digital systems. They form the security bedrock for blockchain technology, digital signatures, and secure transactions. Examples include hashing, public-key cryptography, and zero-knowledge proofs.
Context ∞ The ongoing strength and evolution of cryptographic principles are paramount for the security of digital assets and decentralized networks. News often reports on advancements in cryptographic research, such as post-quantum cryptography, which seeks to protect systems from future computational threats. The proper application of these principles is continuously evaluated for robustness against emerging computational capabilities.
