Abstract: Embodiments of the invention introduce efficient methods for securely generating a cryptogram by a user device, and validating the cryptogram by a server computer. A secure communication can be conducted whereby a user device provides a cryptogram without requiring the user device to persistently store an encryption key or other sensitive data used to generate the cryptogram. The user device and server computer can mutually authenticate and establish a shared secret. Using the shared secret, the server computer can derive a session key and transmit key derivation parameters encrypted using the session key to the user device. The user device can derive the session key using the shared secret, decrypt the encrypted key derivation parameters, and store the key derivation parameters. Key derivation parameters and the shared secret can be used to generate a single use cryptogram key, which can be used to generate a cryptogram for conducting secure communications.

Abstract: Methods, systems, and devices are provided for authenticating API messages using PKI-based authentication techniques. A client system can generate a private/public key pair associated with the client system and sign an API message using the private key of the private/public key pair and a PKI-based cryptographic algorithm, before sending the signed API message to a server system. The server system (e.g., operated by a service provider) can authenticate the incoming signed API message using a proxy authenticator located in less trusted zone (e.g., a perimeter network) of the server system. In particular, the proxy authenticator can be configured to verify the signature of the signed API message using the public key corresponding to the private key and the same cryptographic algorithm. The authenticated API message can then be forwarded to a more trusted zone (e.g., an internal network) of the server system for further processing.
