The Design and Analysis of the Key-Stream Generator Based on the AES

Abstract:

The key-stream generator is the most important algorithm component of the stream cipher. At the present, it is an important development direction of the stream cipher algorithm that uses complex block cipher algorithms to construct high performance key-stream generators. The paper puts forward a new design method of the key-stream generator based on the AES algorithm. This method is based on the CFB mode of the AES algorithm, combined with the variable-step feedback shift. Then the paper analyses the randomness of the key-stream produced by the new key-stream generator. This new key-stream generator really improves the cryptographic properties of the key stream generator and to enhance the security of stream cipher.
