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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods for signaling an attack on contactless cards","description":"Example embodiments of systems and methods for data transmission system between transmitting and receiving devices are provided.
