Abstract :

Nowadays, security is an important factor of internet and network application. Likewise, secure transmission of images is the most challenging aspects. This paper explains the secure end to end transmission of images. Here encryption process is used to ensure the security during the transmission and also hash values of the images are used as verification criteria of the security. Here, to secure the image, calculate the hash value of the image and append this value with the image. Then encrypt the appended image using AES (Advanced Encryption Standard) algorithm, and then send to the receiver. Cryptography is a main category of computer security that converts information from its normal form into an unreadable form. Encryption methods are used to securely transmit data in open networks. Symmetric key algorithms are most suitable for encrypting this multimedia objects. Here AES algorithm is used for encryption and decryption process. Some existing symmetric key algorithms like DES, triple DES with 3 keys and AES have been implemented in different papers. Out of these algorithms DES and Triple DES are not considered as secure algorithms, since some attacks have been found on both algorithms. AES with 128 bit key has proved to be a secure and efficient algorithm.
