Definition ∞ Message integrity refers to the assurance that data or a message has not been altered or corrupted during transmission or storage. Cryptographic techniques, such as hashing, are employed to verify that the content remains precisely as it was originally sent. This property is fundamental for secure communication and data verification.
Context ∞ Discussions of message integrity are relevant when news covers secure communication protocols, data verification on blockchains, or the prevention of data tampering. Reports might detail how cryptographic methods are used to secure transactions or ensure the authenticity of information exchanged between nodes. Understanding message integrity is crucial for assessing the security and trustworthiness of digital communications and data systems.
