AES and Color Coded Cryptography

摘要

In our encryption mechanism, the Plaintext is converted into color coded pixels. The output for certain given input (.txt file/string) is a bitmap image and the companion file without which the file won't decrypt (this is also encrypted in AES for security purpose), the user has to provide password during the encryption phase. The same password is required to decrypt the file. Example: -during the decryption phase all the three viz; image, companion file and password is required if any given value is wrong i.e. the file or password for the given bitmap image will result in an error. This way it makes it difficult for cryptanalyst to analyse the output (the image to gain the information which was present in the actual file). In the case if the user wishes to encrypt any other format file s/he can use "Encrypt with AES" Function of our software and can be decrypted only with the "Decrypt with AES".
