Abstract
A user device generates an initiate interaction request message comprising a state commitment. The user device provides the initiate interaction request message to a first server computer, which creates a verify state request message comprising an interaction index, an interaction index commitment, and a first commitment signature formed from the state commitment and the interaction index commitment. The user device receives the verify state request message, then generates a modified verify state request message comprising a user device public key, the state commitment, the interaction index commitment, and the first commitment signature. The user device provides the modified verify state request message to a second server computer. The second server computer verifies the state commitment, verifies the first commitment signature, and creates a second commitment signature formed from the state commitment and the interaction index commitment. The user device receives a verify state response message comprising the second commitment signature.
