Instant messaging apparatus and method with instant messaging secure policy certificates
First Claim
1. A method for facilitating instant messaging comprising:
- receiving, by a local instant messaging secure public key infrastructure (PKI) proxy, an instant messaging public key cryptography policy certificate for an instant message subscriber; and
controlling operations of the local instant messaging secure PKI proxy for an outgoing or incoming instant message in response to instant messaging policy control data in the IM public key cryptography policy certificate.

Abstract
Briefly, a method and apparatus for facilitating instant messaging generates (e.g. issues) an instant messaging public key cryptography policy certificate containing selected instant messaging public key cryptography policy control information. An instant messaging device obtains the instant messaging public key cryptography policy certificate through the use of a local instant messaging secure public key infrastructure proxy. Based on instant messaging policy control data in the instant messaging public key cryptography policy certificate, operations of the local instant messaging secure PKI proxy are controlled for outgoing and incoming instant messages. Hence, among other advantages, central enforcement of security policies for instant messaging users is provided.
