The Optimum Encryption Method for Image Compressed by AES
In this paper, the idea of partial encoding has been proposed to use for secure encryption of only a portion of compressed data. Only 10% -25% of the output is encrypted from the Quad tree compression algorithm. As a result, the encryption and decryption time has been reduced considerably. Thus, in the compression stage, the Quad tree compression algorithm is used while in the encoding stage, the Advanced Encryption Standard (AES) algorithm is applied. The proposed partial coding system is fast and safe and does not reduce the compression performance of the underlying specific algorithm
