Patent

CA 2277750

In the method for transferring sensitive information using unsecured communication, a first party receives a public key of a second party, produces an encryption result by performing keyed encryption on at least a first random number using the public key, and transfers the encryption result to the second party over an unsecured communication channel. The second party decrypts this encryption result to obtain the first random number. Authorizing information is then transferred from the first party to the second party over a first encrypted and authenticated communication channel established using the first random number. Sensitive information is further transferred from the second party to the first party over a second encrypted and authenticated communication channel established using the first random number if the second party accepts the authorizing information. Numerous applications exist for the system and method, including the wireless industry wherein the first party is a mobile and the second party is a network.
