Abstract:
1. A method for enabling strong mutual authentication on a computer network comprising the steps of: transmitting a first indicia of a user to a first computer over a first communication channel; generating by said first computer a first authentication number, a second authentication number, and a third authentication number; transmitting by said first computer a first message to a second computer, wherein said first message comprises said first authentication number encrypted by said second authentication number; transmitting by said first computer a second message to a verifier over a second communication channel, wherein said second message comprises said second authentication number encrypted and said third authentication number; decrypting by said verifier said second message to obtain a first decrypted message, wherein said first decrypted message comprises said second authentication number; transmitting by said verifier said second authentication number to said second computer over a third communication channel; decrypting by said second computer said first message transmitted by said first computer to recover said first authentication number; transmitting by said second computer a third message to said first computer over said first communication channel, wherein said third message comprises said second authentication number encrypted by said first authentication number; and validating said second computer by said first computer by decrypting said third message to obtain said second authentication number.
