    摘要: A dual-factor PIN based authentication system and method uses a cryptogram provided by a contactless card associated with the client in association with a PIN stored by the contactless card to authenticate the client. In some embodiments, cryptogram authentication may be preconditioned upon a PIN match determination by the contactless card. In other embodiments, the cryptogram may be formed at least in part using the personal identification number (PIN) stored on the contactless card encoded using a dynamic key stored by the contactless card and uniquely associated with the client. Authentication may be achieved by comparing the cryptogram formed using the PIN against an expected cryptogram generated an expected PIN and an expected dynamic key.

    摘要: Disclosed herein are system, method, and computer program product embodiments for signing a document by generating a hash value using a smart card. The smart card can receive from a computing device a first hash value generated for the document based on a first hash function, determine a private key based on a private key information stored on the smart card, sign the first hash value by generating a second hash value based on the first hash value using a second hash function and the private key. The second hash value is to authenticate that the second hash value is generated by the smart card based on the first hash value and the private key. The smart card can further assemble a signature package including the second hash value, and transmit the signature package to the computing device.

    摘要: Example embodiments of systems and methods for data transmission system between transmitting and receiving devices are provided. In an embodiment, each of the transmitting and receiving devices can contain a master key. The transmitting device can generate a diversified key using the master key, protect a counter value and encrypt data prior to transmitting to the receiving device, which can generate the diversified key based on the master key and can decrypt the data and validate the protected counter value using the diversified key. In an embodiment, the transmitting device can signal an attack or potential attack through the counter value. The attack signaling can further include information relating to the attack or potential attack.

    摘要: A contactless card can include a plurality of keys for a specific operation, e.g., encryption or signing a communication. The contactless card can also include an applet which uses a key selection module. The key selection module can select one of the plurality of keys and the applet can use the key to, e.g., encrypt or sign a communication using an encryption or signature algorithm. The contactless card can send the encrypted or signed communication to a host computer through a client device. The host computer can repeat the key selection technique of the contactless device to select the same key and thereby decrypt or verify the communication.
