Abstract:

For replacing the old DES（Data Encryption Standard）, the AES（Advanced Encryption Standard） is put forward, and it has higher security. In this paper, the AES algorithm is expounded in brief. Furthermore, the topic about optimized AES is proposed to satisfy the encryption demand of real-time, field  and transparency, such as audio and video data flow in the field of information security. The technique to implement the optimized AES rapidly in DSP b y software is studled in practice

Key words: （AES algorithm, optimized AES, DSP, encryption data flow）
