A cryptographic primitive is a fundamental building block of cryptographic systems, such as encryption algorithms or hash functions. These primitives are designed to perform specific security-related tasks and are typically characterized by their mathematical properties and resistance to known attacks. They form the basis for constructing more complex cryptographic protocols and applications.
Context
The ongoing development and analysis of cryptographic primitives are central to maintaining the security of digital assets and blockchain networks.
