Patent attributes
A disclosed enterprise instant messaging (IM) service aggregator enables validation of mobile stations and/or users for enterprise IM service through a wireless communication network; and in the examples, the enterprise IM service provides a secure messaging environment that allows IM traffic to/from wireless mobile stations. The security offered may be unique to and controlled by each enterprise, for example, by enabling each enterprise to generate its own encryption key for distribution through the aggregator and by allowing mobile stations to generate their own keys for distribution back through the aggregator to the enterprise IM servers. As disclosed, the login credentials are encrypted from the mobile station to the enterprise IM server. The use of standard encryption methods within the call flows allows a simple method of ensuring that only authorized users can access the enterprise servers and that the messages will be encrypted by the strongest possible means.
