EFTPOS Initialisation using RSA Cryptography

Before you start with RSA, you should generate a public and private key pair using your HSM. These can be group keys or specific to the terminal you need to connect. Your terminal manufacturer will also provide its public key and modulus. Using these keys you will be able to calculate the TMK1 and TMK2Continue reading “EFTPOS Initialisation using RSA Cryptography”

Interchange Cryptographic Keys  Interchange keys are used to protect financial transactions initiated at Acquirer eftpos / ATM Terminals while in transit to the Issuer institution. Interchange keys may be either: (a) PIN encrypting keys – used to protect the customer PIN from the point of origin to the point of authorisation. PIN encrypting keys areContinue reading “Thales 9000 with AS2805 Interchange & RSA EFTPOS Commands.”
