Secure transmission of multimedia objects

Author:

Santhi Mol, P. and Supriya, L. P.

Subject Area:

Physical Sciences and Engineering

Abstract:

Network security measures are needed to protect data or information during the transmission. Security is an important factor in the network transmission. Secure transmission of multimedia object means the secure transmission of text, image, audio and video. Cryptographic techniques provide the security during transmission of multimedia objects. Cryptography means converting data from readable form to unreadable form. Advanced Encryption Standard (AES) algorithm provides greater security for data. Here, AES algorithm with 128 bit key is used for encryption and decryption process. Secure hash value is calculated for ensuring the security. SHA1 algorithm is used for calculating the hash value of the multimedia objects. AES algorithm prevent various types of attacks like message disclosure, replay attack etc.
