Abstract:
Data is encrypted according to a plurality of data keys. During the encryption of the data, the data keys are rotated according to a data key rotation pattern, and the rotation of the data keys includes repetitive use of the data keys during the encryption of the data. The encrypted data is transmitted to a receiver. Additionally or alternatively, encrypted data is received from a transmitter. The encrypted data is decrypted according to a plurality of data keys. During the decryption of the encrypted data, the data keys are rotated according to a data key rotation pattern, and the rotating of the data keys includes repetitive use of the data keys during the decryption of the encrypted data.
