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 secure encrypted communication, comprising:
- a. a key generating component adapted to be mounted on an individual'"'"'s body for wirelessly transmitting within the immediate proximity of the individual when the key generating component is mounted on the individual'"'"'s body, a key signal comprising secret or private key information corresponding to the time variable secure key information to facilitate secure wireless communication in accordance with the encryption algorithm; and
b. a handheld wireless component, physically separated from the key generating component, adapted to (a) wirelessly receive the key signal transmitted by the key generating component, (b) use the secret or private key information included in the key signal to encrypt a message in accordance with the predetermined encryption algorithm, and (c) transmit the encrypted message via 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 a third party that has communicated with the certification authority in accordance with the encryption algorithm.

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.
