The Common Electronic Purse Specifications (CEPS) define an electronic purse program built on the EMV specification. The CEPS scheme extends the EMV authentication architecture with a certification authority (CA) and issuer certificates to include the Acquirer side. The Acquirer is responsible for managing Point Of Sale (POS) transactions using a Purchase Secure Application Module (PSAM). The terminal (PSAM) authenticates itself to the smart card and does so using a method similar to the approach of EMV. On the card is stored an issuer-side CA index, an issuer certificate, and a card certificate which is transmitted to the terminal. Using a stored issuer CA certificate, the terminal verifies the issuer certificate and the card certificate. The terminal responds by generating a digital signature—using a terminal private key—which is encrypted by the card public key and transmitted to the card together with a corresponding terminal certificate on the public key, an acquirer certificate,...
