Recently, as network and computer technologies are growing rapidly, most of business transactions are performed in cyber world. In spite of many advantages. the most concerns in Electronic Commerce are the information security matters, and the cryptosystem has been claimed as one of the proper means to settle this problem. In this paper, a partial encryption/decryption algorithm has been in-troduced to show the efficiency against the conventional method in which all the data are completely encoded. In our proposed scheme, the multimedia data can be efficiently encoded in a short time pro-viding good data security. For example, the MP3 data can be securely protected with 10% encryption in our scheme. Moreover, the shuffling process at the end of partial encryption procedure provides higher level of data security.
