| Abstract | ||
| The use of image communication has increased in recent years. In this paper, new partial encryption schemes are used to encrypt only part of the data. Only 6.25-25% of the original data is encrypted for four different images, resulting in a significant reduction in encryption and decryption time. In the encryption step, the Advanced Encryption Standard (AES) cipher, stream cipher and permutation cipher are used. On the other hand, we will use a combination of two encryption methods may be used to achieve high security and make brute fore attack infeasible. The effect of size of encrypted data on performance of the proposed techniques are studied. The proposed partial encryption schemes are fast and secure | ||
