Cryptographic Integrity

Definition ∞ Cryptographic Integrity denotes the assurance that data has not been altered or corrupted in an unauthorized manner, particularly during transmission or storage. It relies on cryptographic techniques, such as hashing and digital signatures, to detect any modifications, thereby guaranteeing the authenticity and immutability of digital information. In the context of digital assets and blockchain technology, maintaining cryptographic integrity is fundamental for verifying transaction validity and ensuring the trustworthiness of ledger entries.
Context ∞ News concerning cryptographic integrity often arises in discussions about the security of blockchain protocols, the immutability of smart contracts, or the prevention of data tampering in distributed systems. Any perceived compromise in cryptographic integrity can lead to significant concerns regarding the reliability and security of digital assets and the underlying infrastructure they depend upon. Consequently, advancements or vulnerabilities in cryptographic methods are closely monitored by industry participants and regulators.
