Abstract:
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; wherein the time variable key generated by said key generating component is an authenticating key that uniquely identifies to the certification authority the individual upon which said key generating component is mounted and wherein said authenticating key and the corresponding secure key information held by the certification authority change in time in accordance with said key generating algorithm in a manner to permit the certification authority to uniquely and securely certify the identity of the individual to whom the key generating component was provided; 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 transmission 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.
