  • Tamper-resistant secure methods, systems and apparatuses for credit and debit transactions
    Patent number: 10748146
    Abstract: An electronic payment transaction involves operating a gateway device in an electronic payment system to receive first encrypted transaction data from a merchant device, wherein the first encrypted transaction data is encrypted by means of a merchant device-specific encrypting key. Decrypted transaction data is produced by using a merchant device-specific decrypting key to decrypt the first encrypted transaction data. Second encrypted transaction data is derived from the decrypted transaction data, wherein the second encrypted transaction data is encrypted by means of a gateway device-specific encrypting key. The gateway device communicates the second encrypted transaction data to another electronic payment system server. A key transmission block received from the merchant device includes information that enables the gateway device to derive the merchant device-specific decryption key.
