Abstract
A method and apparatus for improving hardware flexibility for encrypting data based on the Advanced Encryption Standard (AES) block algorithm is provided. An encryption apparatus is equipped with a shared logic including a mode detector which detects a current AES mode performed by an AES block algorithm, a shared hardware for use in the detected AES mode, and a key controller which generates a key for performing encryption/decryption in the AES mode.
Claims6
An encryption apparatus for use in a base station, the encryption apparatus having a shared logic and comprising:
- a mode detector for detecting, in the base station, a current Advanced Encryption Standard (AES) mode performed by an AES block algorithm;
- a shared hardware for performing the AES block algorithm to operate the detected AES mode;
- and
- a key controller for generating a key for performing encryption/decryption in the AES mode.
An encryption method based on an Advanced Encryption Standard (AES) block algorithm, the encryption method for use in an encryption apparatus in a base station and comprising:
- checking, in a mode detector, an AES mode in which the AES block algorithm operates;
- performing the AES mode, by a shared hardware of the encryption apparatus for use in the AES mode;
- and
- generating, by a key controller, a key for performing encryption/decryption in the AES mode.
