With this method, both the request for the software and the software itself are encrypted so that they cannot be read by anyone but the intended recipient. The request would take the form of a license agreement that the user signs using his or her public key to indicate agreement to the terms and conditions for using the software. Sebastopol, California, 1995. The decrypt reverses this procedure. Decrypting an encrypted agent instantiates that agent, which receives the Restart event.
Believability is concerned with the credibility of information.
In this paper s framework, a credential can be a string message or, as we explained in Section 2, another agent. The latter is known as an active credential. For example, in a networked environment with a central file server, traditional Unix file protections can be easily circumvented by monitoring the network traffic. However, stand alone encryption tools can be time consuming and are not easily integrated with existing application binaries. O'Reilly and Associates, Sebastopol, CA, first edition, December 1994.
