Security system for handheld wireless devices using time-variable encryption keys
First Claim
1. 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 over a network, comprisinga. a body mounted key generating component adapted to be mounted on an individual'"'"'s body for wirelessly broadcasting within the immediate proximity of the individual a key signal corresponding to the time variable secure key information under the control of the certification authority in order to facilitate secure wireless communication with the individual in accordance with the encryption algorithm;
- andb. a handheld wireless component adapted to receive the key signal broadcast by the key generating component for use in implementing secure communication in accordance with the predetermined encryption algorithm via signals transceived over a wireless link that forms part of a communication channel connected at one end to said handheld wireless component and connected at the other end to third parties that are or have communicated with the certification authority in accordance with the encryption algorithm,wherein said certification authority implements the encryption algorithm to allow encrypted communication between the certification authority and each of the individuals over the wireless network, said certification authority including a memory for storing an operating program and for storing subscriber identification information adapted to be associated with time variable key information corresponding to the time variable keys generated in each of the corresponding key generating components and used by the respective handheld components to form an encrypted message for broadcast over the wireless network to the certification authority wherein the certification authority can authenticate any encrypted message forwarded to said certification authority as coming from a particular individual by implementing an authentication routine of the encryption algorithm using the associated time variable key information.

Abstract
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 and networks.
