Abstract
Methods and systems for protecting data may include controlling encryption and/or decryption and identifying a destination of corresponding encrypted and/or decrypted data, utilizing rules based on a source location of the data prior to the encryption or decryption and an algorithm that may have been previously utilized for encrypting and/or decrypting the data prior to the data being stored in the source location. The source location and/or destination of the data may comprise protected or unprotected memory. One or more of a plurality of algorithms may be utilized for the encryption and/or decryption. The rules may be stored in a key table, which may be stored on-chip, and may be reprogrammable. One or more keys for the encryption and/or decryption may be generated within the chip.
