SECURELY UPGRADING AN UNTRUSTED CHANNEL INTO A TRUSTED CHANNEL

摘要

Methods, apparatus and systems for upgrading an untrusted channel to a trusted channel. In an embodiment, a verifier server computer receives a request to verify an untrusted channel address from a first service component that is associated with a Consumer identifier, retrieves a trusted channel address from a verifier database, and then generates a one-time password witness value. The verifier server computer then splits the one-time password witness value into a first portion and a second portion, and transmits the first portion to the first service component and transmits the second portion to the second service component. The process includes receiving a recomposed value from the first service component, splitting the recomposed value into a first recomposed value and a second recomposed value, generating a reverted one-time password value, determining that the reverted one-time password value equals the one-time password witness value, and then transmitting an authentication message to the first service component confirming authentication of the consumer enabling upgrading of the untrusted channel to a trusted channel.
