Cryptographic security involves the use of mathematical techniques to protect information and communications. It encompasses methods like encryption, digital signatures, and hashing to ensure confidentiality, integrity, and authenticity. These principles are vital for securing transactions, verifying identities, and safeguarding digital assets within decentralized systems. The strength of cryptographic primitives underpins the trust and functionality of many digital technologies.
