Security Primitives

Definition ∞ Security primitives are fundamental, low-level cryptographic algorithms or protocols that serve as basic building blocks for constructing more complex security systems. Examples include hash functions, encryption algorithms, and digital signatures. These elements provide core security properties like confidentiality, integrity, and authenticity. They are the foundation of secure systems.
Context ∞ In blockchain and decentralized systems, security primitives are the bedrock of cryptographic security, securing transactions, smart contracts, and user identities. The strength and correct implementation of these primitives directly determine the overall security of digital assets. News often discusses advancements in cryptographic research that yield new or improved primitives, enhancing the resilience of blockchain protocols.
