1. Mobile Single Sign On System Souheil Lazghab

2. The security protocol should secure: First, the Bluetooth communication between the PICDEM FS USB Demo board and the mobile phone device. Second, the access credentials stored in the RMS residing on the mobile phone. Third, provide a secure authentication mechanism between the user and the sso MIDlet.

4. To achive these goals: RC4 SHA-1 AES-128

5. Problems! The limitation of the processing power and storage size of the PICDEM FS USB Demo board device. The limitation of the development environment for both Java and embedded system.

6. Conclusion 100 % security does never exist in any system. The security protocol offers a good security level to the SSO prototype. The degree of security could be ameliorated if it will be included early in the design process.
