Abstract

A method of generating a public key in a secure digital communication system, having at least one: trusted entity CA and subscriber entities A, the method comprising the steps of: for each entity A, the CA selecting a unique identity I A distinguishing the entity A; generating a public key reconstruction public data .gamma.A of entity A by mathematically combining a generator of the trusted party CA with a private value of the entity A, such that the pair (I A, .gamma.A ) serves as A's implicit certificate; combining the implicit certificate information (I A, .gamma.A ) in accordance with a mathematical function F(.gamma.A , I A) to derive an entity information f; generating a private key a of the entity A by signing the entity information f and transmitting the private key a to the entity A, whereby the entity A's public key may be reconstructed from the public information, the generator .gamma.A and the identity I A relatively efficiently.
