Joint AES and RSA for High-Definition Image Stream Safety with Key Managed

ABSTRACT

High definition images have been applied in more and more scenarios. Meanwhile, the demand for the safety of these image data is also increasing. In this paper, we firstly investigated the features existing in the high definition images and then studied the theory of the AES and RSA algorithms. However, the AES algorithm has some weaknesses when used, such as effectiveness in running and safety with used keys. In connection with the safety of image data and the used keys in the AES, we made some alterations on the AES algorithm and combined the AES and RSA algorithms to provide protection with centralized key management frame. For operating convenience, the paper introduces Data Stream Recognition mechanism to provide instruction on image stream with added stamps. After this, the safety of image data stream and the efficiency for handling images are both enhanced. Our outcome can be applied in data protection, especially when used in embedded operating system.
