What does CHV mean in UNCLASSIFIED

CHV stands for Current Hash Value. It is a mathematical calculation used to ensure the integrity of digital data by verifying that the information has not been altered or tampered with.

A CHV provides a digital fingerprint that can be used to detect changes in data and protect against malicious attacks.

A CHV is typically generated using an algorithm such as SHA or MD5, which processes input data (such as plain text) and generates a fixed-length string of numbers and letters known as the ‘hash' value.

A CHV may be stored alongside other data and checked on retrieval to verify that no changes have occurred since storage. This helps provide protection against malicious attacks and unauthorized modifications to files and databases.

Some advantages include providing strong authentication measures, ensuring efficient detection of any discrepancies between stored values, allowing for quick identification when searching large databases, and enabling secure data transfer between systems.
