Abstract:
A plaintext and cryptographic key are used to generate an initialization vector to be used in a cryptographic algorithm, such as an encryption algorithm. In some examples, the plaintext and cryptographic key are input into an effectively one-way function, such as a cryptographic hash function, the output of which is usable as an initialization vector. Cryptographic keys may be rotated probabilistically based at least in part on probabilities of output collisions of the effectively one-way function to ensure a low probability of two different plaintexts resulting in calculation of the same initialization vector for use with the same cryptographic key.

Claim (Index 16):
The non-transitory computer-readable storage medium of  claim 15 , wherein the initialization vector is generated based at least in part on a cryptographic hash function applied to inputs comprising the data.
