	Abstract:This paper describes a secure email system especially how to design his personal email system by handling both symmetric-key and public-key techniques. The system consists of a mail server to manage the sending and receipt of the email, a data base to manage the certificates corresponding to different emails. A model is implemented to check the certificate from the certification authority then save it into the database, then another model implemented to encrypt the email by using first the symmetric-key with AES encryption then use the public key technique to encrypt the symmetric-key with RSA encryption technology before sending. A model is designed to sign the email with the sender's private key to minimize spam and others virus and threats, to be sure of the email source. With all its commands, the library OpenSSL will be a very important toolkit. As a result of the project on building automation, the tool interface used is the command line interface. All the sending email process must be transparent to the user, easily handy and especially reliable with all security precautions.

	Abstract:RBAC (Role-Based Access Control, RBAC) role-based access technology is the study of R & D results funded by the U.S. Department of Defense (Department of Defense, DoD)-. The initial research is proposed in order to prevent system-specific confidential information from unauthorized access, recent policy is applied to these applications as a commercial field.This model of system permission control contribute to better use of resources in the system and maintain system security.
