ABSTRACT:
A system and method for secure sharing of electronic information uses public key encryption in which a key generator algorithmically generates public-private key pairs without requiring storage, maintenance, tracking and management of keys or certificates. The algorithm uses one or more unique attributes of an individual to generate the public private key pair for that individual. In a preferred embodiment, the one or more unique attributes are input to a random number generator which outputs random numbers used to generate the public-private key pairs that are used for secure communication.
