Recently, as network and computer technologies are growing rapidly, many parts of business transactions, are performed in cyber market and therefore, "electronic commerce" is expanding in proportion to the spread of Internet. In spite of many advantages, Electronic Commerce has some problems in which the information related to the business could be tapped because of the characteristic of an open architecture. So, the most important thing in building Electronic Commerce is 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 introduced to show the efficiency against the conventional method in which all the data are completely encoded. In our suggested method, the multimedia data can be efficiently encoded in a short time providing good data security against the conventional method. Moreover, the shuffling process at the end of partial encryption procedure provides higher level of data security. Consequently, our suggested scheme shorten the encryption/decryption time at the server and client, and provides good infomation protection.
