1. A certification apparatus for a secure wireless personal communication system using an encryption algorithm, the secure wireless personal communication system serving a plurality of users, each of whom has a handheld wireless component for encrypting information for broadcast over a wireless communication channel using a time variable key and a body mounted paired key generating component adapted to be mounted permanently or semi-permanently on the user for wirelessly broadcasting a time variable key signal including the time variable key required by the encryption algorithm within an immediate proximity of the user, wherein said certification apparatus comprises:

  • a. a memory for storing an operating program, encryption program, and user identification information uniquely associated with each of the users of the secure wireless personal communication system; and

    b. a data processor adapted to implement the operating program and the encryption program to generate time variable keys corresponding uniquely with the time variable keys generated by each of the body mounted paired key generating components, mounted on the respective users, to allow the respective users to communicate securely and to be authenticated to third parties, who communicate with the respective users over wireless communication channels,wherein the certification apparatus can authenticate each user and facilitate encryption of information broadcast or received over wireless communication channels accessed by each user by using a corresponding time variable key,wherein said certification apparatus implements a Public Key Infrastructure, PKI, type encryption algorithm for generating a series of public keys corresponding one to one to a sequential series of secret or private keys generated from time to time by said body mounted paired key generating component in accordance with a predetermined Public Key Infrastructure, PKI, key generation algorithm and wherein said time variable key signal broadcast by the body mounted paired key generating component is a private key corresponding to a current public key used by the certification apparatus to facilitate secure communication between third parties and the user who has been authenticated by the certification apparatus, andwherein said predetermined PKI key generation algorithm employs a predetermined sequence of paired private keys and public keys wherein the private keys and the public keys are generated and provided, respectively, to the body mounted paired key generating component and to the certification apparatus to be used in the future in accordance with the predetermined PKI key generation algorithm to cause a current private key broadcast by said body mounted paired key generating component to properly correspond to a public key provided by the certification apparatus to facilitate third party communication with the user.
