Systems and methods for generating shared secret key for transaction cards

Abstract

Systems and methods for generating a shared secret key for a transaction card are provided. An exemplary system can include: a transaction card including a card private key and a card public key derived from the card private key; a server including a server private key and a server public key derived from the server private key; and a user device. The user device can be configured to: open a communication field, read the card public key, transmit the card public key to the server, wherein the server generates a shared secret key from the card public key and the server private key, receive the server public key from the server, and transmit the server public key to the transaction card, wherein the card generates the same shared secret key from the server public key and the card private key.
