IV

Definitions

1. Short for initialization vector, a non-secret value used with certain encryption modes to ensure the same plaintext does not always produce the same ciphertext. Choosing and handling IVs correctly is essential because predictable or reused IVs can break the intended security of a scheme.

   In plain English: A value used in encryption so repeated data does not always encrypt the same way.

   Example: "The encryption bug came from reusing the same IV for too many records under the same key."
