With the continuous promotion of high and new technologies such as computers big data, humans enter a period-information age. Mass data information can be transmitted exchanged online through network. In recent years, research on image encryption based optical processing technology is becoming more favored by researchers. this regard, study will focus algorithms in images realize fractional Fou...

Data encryption is the conversion of data into a form, called a ciphertext, that cannot be easily understood by unauthorized people. Decryption is the process of converting encrypted data back into its original form, so it is easily understood. In literature, different techniques are used for encryption and decryption of text, image, audio and video. RSA (Rivest, Shamir, Aldeman) encryption tec...
