H11C6 Article About

For mobile application security example, we need only study Java applet, which uses digital signatures and security SandBox to ensure the safety code on the Web. It? Is applet security works on a brief overview: Before the transfer, applet server certificate with its digital signature on the applet JAR files. In the reception, the browser-side Java Security Manager to verify the signature and determine the applications credibility and integrity of the sender. If you can not verify the digital signature, then run out and gives error message. If you can verify the signature, the security manager uses a digital certificate, the client or by check through the use of tables to query the trusted entitys authority to determine the entitys rights field. After the successful completion of the verification process, the application code is delivered to the client. And the Java applet can be used as a way of action based on J2ME/CDC to sign and pass code. In theory, the same method can also be protected with MIDP applications. However, due to the limited processing power and memory, MIDP 1.0 specification does not use domain-based security manager. The current MIDP VM can only provide minimal security SandBox. For example, MIDlet suite can access only its own to create a lasting record store. Network and data security
