  • Publication number: 20210176062
    Abstract: Techniques are described for managing master keys for token requestors to use in generating cryptograms such as TAVVs. A processor computer generates a first master key for a token requestor, the first master key being generated based on (a) a second master key managed by the processor computer and (b) an identifier of the token requestor. The processor computer transmits, to a token requestor computer corresponding to the token requestor, the first master key. The processor computer receives, from the token requestor computer, a request for a token. Responsive to receiving the request for the token, the processor computer transmits the token to the token requestor computer; and receives, from the token requestor computer, an authorization request message comprising the token and a cryptogram generated by the token requestor computer using the first master key and the token.

  • Publication number: 20210126939
    Abstract: Systems, methods, and devices are disclosed for preventing relay attacks. A user device may receive (e.g., when proximate to the first access device), from an intervening device, device identification data for a first access device. A message may be received from a second access device via the intervening device. The message may include a digital signature generated based at least in part on second access device identification data. The user device may validate the message utilizing the digital signature and a public key. If the message is invalid, the user device may discard the message. If the message is valid, (e.g., unaltered), the user device may determine that the user has not confirmed an intent to interact with the second access device and may terminate an further interaction with the second access device accordingly.

  • Publication number: 20210058259
    Abstract: Some embodiments provide systems and methods for confidentially and securely provisioning data to an authenticated user device. A user device may register an authentication public key with an authentication server. The authentication public key may be signed by an attestation private key maintained by the user device. Once the user device is registered, a provisioning server may send an authentication request message including a challenge to the user device. The user device may sign the challenge using an authentication private key corresponding to the registered authentication public key, and may return the signed challenge to the provisioning server. In response, the provisioning server may provide provisioning data to the user device. The registration, authentication, and provisioning process may use public key cryptography while maintaining confidentiality of the user device, the provisioning server, and then authentication server.
