Research on encryption technology based on J2ME socket network communication

With the rapid development of wireless communication and Java technique, the wireless applications built on Java is of great promise. So it´s important to pay more attention to their security. Based on the introduction of J2ME, this article also analyzes how to secure the new booming wireless application of J2ME, especially on small wireless device.This paper introduces communication technology on wireless networks based on the J2ME platform, deeply analyses the J2ME platform, and analyses the communication theory on programming interfaces of socket network; and then analyzes and compares several common encryption algorithms such as MD5, SHA1 and BASE64, etc. According to the performance and features of mobile phone network, I propose an encryption solution based on J2ME Socket protocol, realize this encryption program and give the source code of this encryption program in this paper.
