Abstract
Systems and methods for ensuring data security. A MAC is computed sequentially for each selected message from a data log that contains at least two messages. To build a data block, a preset encryption key is used for a first message and an encryption key for the previous message is used for subsequent messages. A determination that the data log is compromised can be made based on MAC data block data and an independent calculation of a MAC.
