Systems and methods for signaling an attack on contactless cards
First Claim
1. An attack signaling system comprising:
- a contactless card including a substrate, one or more processors, and a memory; and
one or more servers in data communication with the contactless card,wherein the contactless card is configured to, upon detection of a potential attack, create a one-time password (OTP) value that is transmitted to the one or more servers, the OTP value indicative of the potential attack; and
wherein the one or more servers, upon receipt of the OTP value, are configured to perform one or more protective actions.

Abstract
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.

10. A method for signaling a potential attack by a contactless card in data communication with a server, comprising:
-
receiving, by the server, one or more codes from the contactless card; determining, by the server that the one or more codes are indicative of the detection of a potential attack on the contactless card; and performing, by the server, one or more protective actions in response to the one or more codes. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A contactless card comprising:
-
a substrate, one or more processors, and a memory, wherein the memory contains at least one key, wherein the contactless card is configured to, upon detection of a potential attack; generate a one-time password; transmit the one-time password; receive one or more protective action requests based on the one-time password; and destroy, responsive to one or more protective action requests, one or more, of the at least one key. - View Dependent Claims (20)
