In one embodiment, the invention provides a portable wireless personal communication system for cooperating with a remote certification authority to employ time variable secure key information pursuant to a predetermined encryption algorithm to facilitate convenient, secure encrypted communication. The disclosed system includes a wireless handset, such as PDA, smartphone, cellular telephone or the like, characterized by a relatively robust data processing capability and a body mounted key generating component which is adapted to be mounted on an individual's body, in a permanent or semi-permanent manner, for wirelessly broadcasting, within the immediate proximity of the individual, a secret or private key identifying signal corresponding to a time variable secure key information under the control of the certification authority. The key identifying signal is generated in a format that facilitates secure wireless communication with the individual in accordance with a predetermined encryption algorithm including a PKI encryption algorithm. The disclosed system may be used with a console for coordinating access to a variety of different communication system networks.
