安全电子交易协议

People today pay for online purchases by sending their credit card details to the merchant. A protocol such as SSL or TLS keeps the card details safe from eavesdroppers, but does nothing to protect merchants from dishonest customers or vice-versa. SET addresses this situation by requiring cardholders and merchants to register before they may engage in transactions. A cardholder registers by contacting a certificate authority, supplying security details and the public half of his proposed signature key. Registration allows the authorities to vet an applicant, who if approved receives a certificate confirming that his signature key is valid. All orders and confirmations bear digital signatures, which provide authentication and could potentially help to resolve disputes.

A SET purchase involves three parties: the cardholder, the merchant, and the payment gateway (essentially a bank). The cardholder shares the order information with the merchant but not with 在线交‪易‬ 在线交‪易‬ the payment gateway. He shares the payment information with the bank but not with the 在线交‪易‬ merchant. A set dual signature accomplishes this partial sharing of information while allowing all parties to confirm that they are handling the same transaction. The method is simple: each party receives the hash of the withheld information. The cardholder signs the hashes of both the order information and the payment information. Each party can confirm that the hashes in their possession agrees with the hash signed by the cardholder. In addition, the cardholder and merchant compute equivalent hashes for the payment gateway to compare. He confirms their agreement on the details withheld from him.

All parties are protected. Merchants do not normally have access to credit card numbers. Moreover, the 在线交‪易‬ mere possession of credit card details does not enable a criminal to make a SET 在线交‪易‬ purchase; he needs the cardholder’s signature key and a secret number that the cardholder receives upon registration. The criminal would have better 在线交‪易‬ 在线交‪易‬ luck with traditional frauds, such as ordering by telephone. It is a pity that other features of SET (presumably demanded by merchants) weaken 在线交‪易‬ these properties. A merchant can be authorized to receive credit card numbers and has the option of accepting payments given a credit card number alone.

SET is a family of protocols. The five main ones are cardholder 在线交‪易‬ registration, merchant registration, purchase request, payment authorization, and payment capture. There are many minor protocols, for example to handle errors. SET is enormously more complicated than SSL, which merely 在线交‪易‬ negotiates session keys between the cardholder’s and merchant’s Internet service providers. Because of this complexity, much of which is unnecessary, the protocol is hardly used. However, SET contains many features of interest:

The model is unusual. In the registration protocols, the initiator possesses no 在线交‪易‬ digital proof of identity. Instead, he authenticates himself by filing a registration form whose format 在线交‪易‬ is not specified. Authentication takes place outside the protocol, when the cardholder’s bank examines the completed form.

The dual signature is a novel construction. The partial sharing of information among 在线交‪易‬ three peers leads to unusual protocol goals.

SET uses several types of digital envelope. A digital envelope consists of two parts: one, encrypted using a public key, contains a 在线交‪易‬ fresh symmetric key K and identifying information; the other, encrypted using K, conveys the full message text. Digital envelopes keep public-key encryption to a minimum, but the many symmetric keys complicate the reasoning. Most verified protocols distribute 在线交‪易‬ just one or two secrets.

SET支付系统主要由持卡人(CardHolder)、商家(Merchant)、发卡行(Issuing Bank)、收单行(Acquiring 在线交‪易‬ Bank)、支付网关(Payment Gateway)、认证中心(Certificate Authority)等六个部分组成。对应地,基于SET协议的网上购物系统至少包括电子钱包软件、商家软件、支付网关软件和签发证书软件。
