Claim Text:
1. A method for generating public and private keys in a public key-private key cryptographic scheme, the method comprising: a) receiving, at a computing device from a server, multiple portions comprising at least a first portion p1 and a second portion p2 of an initial value e by way of different communication channels, each of said multiple portions being transmitted by a communication channel which is separate and different from communication channels used to transmit other portions of said initial value; b) receiving, at said computing device from a user, a secret string value generated by said user; c) converting, at said computing device, said secret string value into a digital secret string value s; d) concatenating, at said computing device, said multiple portions p1 and p2 to recreate said initial value e; e) receiving, at said computing device, at least one system parameter r from said server; f) using said multiple portions, said initial value, said at least one system parameter, and said digital secret string value to generate a public key-private key pair for said scheme at said computing device by: wherein said cryptographic scheme further comprises, at a further computing device configured to receive a communication from said computing device:
