19、ion The eCommerce environment is inherently high-risk. This is especially true for PIN-based transactions because if PIN security in this environment is deficient, there is a high probability, in some cases, that card and PIN data might be fraudulently captured and reused in the ATM, POS or eCommerc

20、e environments. For conducting eCommerce transactions, cardholders use network access devices (NAD) of their choice. ISO 9564-1 prohibits PINs from being entered on NADs. This part of ISO 9564 defines minimum security requirements and practices for acceptable devices used for the entry of the PINs i

21、n the eCommerce environment: devices that are compliant with ISO 9564-1 (i.e. PEDs); devices that are not compliant with ISO 9564-1 but are functionally secure devices for PIN entry (FSPED) for exclusive use with IC cards; devices that are not compliant with ISO 9564-1 b u t a r e I C c a r d s w i

23、of ISO 9564 provides requirements for the use of personal identification numbers (PIN) in eCommerce. The PINs in scope are the same cardholder PINs used as a means of cardholder verification in card-based financial transactions; notably, automated teller machine (ATM) systems, point-of-sale (POS) te

24、rminals, automated fuel dispensers, and vending machines. It is applicable to financial card-originated transactions requiring verification of the PIN and to those organizations responsible for implementing techniques for the management of the PIN in eCommerce. The provisions of this part of ISO 956

25、4 are not intended to cover passwords, passcodes, pass phrases and other shared secrets used for customer authentication in online banking, telephone banking, digital wallets, mobile payment, etc., management of cardholder PINs for use as a means of cardholder verification in retail banking systems

26、in, notably, automated teller machine (ATM) systems, point-of-sale (POS) terminals, automated fuel dispensers, vending machines, banking kiosks and PIN selection/change systems, which are covered in ISO 9564-1, card proxies such as mobile phones or key fobs, approved algorithms for PIN encipherment,

27、 which are covered in ISO 9564-2, the protection of the PIN against loss or intentional misuse by the customer or authorized employees of the issuer, privacy of non-PIN transaction data, protection of transaction messages against alteration or substitution, e.g. an online authorization response, pro

42、ment. eCommerce occurs in an open network environment and the cardholder uses a network access device (NAD) to perform an eCommerce transaction. In the open network environment, the NAD may initiate a transaction with any open-network-connected merchant. In eCommerce, the device into which the PIN i

43、s entered might not be under the control of the merchant or the merchants acquirer. For card payment transactions based on PIN, the eCommerce model introduces some fundamental changes with respect to the POS environment: the NAD may be a general purpose computing device connected to an open network

44、and therefore cannot be considered secure; the NAD, which may include a numeric keypad, has not been manufactured in order to be compliant to the requirements of the payments industry; ISO 2016 All rights reserved 3BS ISO 9564-4:2016ISO 9564-4:2016(E) the NAD is not under the control of the merchant

45、, issuer or the merchants acquirer. As a consequence, the NAD is not acceptable for PIN entry. Clause 5 specifies the requirements for the secure handling of PINs in the eCommerce environment. 5 PIN handling requirements 5.1 General A PIN shall not be entered into a network access device (NAD), incl

46、uding, but not limited to, personal computers, mobile phones, etc. Personal devices used for PIN entry in eCommerce shall be for the exclusive use of the cardholder. The use of public (shared) PIN entry devices is restricted to PEDs defined in 5.4 and 5.5. 5.2 Functionally secure PIN entry devices (

47、FSPED) Functionally secure PIN entry devices (FSPED) are limited functionality PIN entry devices that shall be approved by the issuer for use in conjunction with any of that issuers IC cards for offline OTT generation. FSPEDs that support software updates shall have a cryptographic relationship with

48、 the card issuer but the associated cryptographic keys shall not be used for PIN encipherment. The device shall only apply software updates that it has cryptographically authenticated and shall ensure that the software updates are applied in the correct order (an older update cannot be applied after

49、 a newer one has already been applied). An FSPED shall contain a contact IC reader for communication with an IC card. The device shall also contain a keypad for PIN entry and a display screen. Following entry of a PIN (which may be verified by the IC card), the FSPED interacts with the IC card to produce an OTT for subsequent verification by the issuer. The IC card generates a cryptographic value. This value may be used directly as the OTT or the FSPED may format this value to an
