在线交‪易‬

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 在线交‪易‬ this situation by requiring cardholders and merchants to register before they may engage in transactions. A 在线交‪易‬ 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 在线交‪易‬ 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 在线交‪易‬ 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 the payment gateway. He shares the payment information with the bank but not with the merchant. A set dual signature accomplishes this partial sharing of 在线交‪易‬ 在线交‪易‬ information while allowing all parties to confirm that they are handling the same transaction. The 在线交‪易‬ method is simple: each party receives the hash of the withheld information. The cardholder signs 在线交‪易‬ the hashes of both the order information and the payment information. Each party can confirm that the hashes in their possession agrees 在线交‪易‬ 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 mere possession of credit card details does not enable a criminal to make a SET purchase; he needs the cardholder’s signature key and a secret number that the cardholder receives upon registration. The criminal would have better luck with traditional frauds, such as ordering by telephone. It is a pity that other features of SET (presumably demanded by merchants) weaken these properties. A merchant 在线交‪易‬ can be authorized to receive credit card numbers and has the option of accepting payments given a credit card number alone.

SET is 在线交‪易‬ a family of protocols. The five main ones are cardholder registration, merchant registration, purchase request, payment authorization, and payment capture. There are 在线交‪易‬ many minor protocols, for example to handle errors. SET is enormously more complicated than SSL, 在线交‪易‬ which merely 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 digital proof of identity. Instead, he authenticates himself by filing a registration form whose format is not specified. Authentication takes place outside the protocol, when the cardholder’s bank 在线交‪易‬ examines the completed form.

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

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

关于网络支付你不可不知的反欺诈手段

新的支付形式也催生了新的欺诈手段。在支付环节,黑色产业集团往往通过社工方式和技术手段, 盗取利用个人姓名、手机号码、身份证号码和银行卡号等直接关系账户安全的要素,并进一步用于进行精准诈骗、恶意营销。虚假WiFi、病毒二维码、盗版APP 客户端以及木马链接等是盗取用户私人信息的主要手段,获得的关键信息被收入数据库分类储存,其中,账户信息(如游戏账户、金融账户) 通过黑色产业链进行金融犯罪和变现,用户真实信息除了贩卖外,更多用于商城盗刷。

某大学生发现自己银行卡里的5 万元“不翼而飞”。反复查询,他被通知自己在某电商平台注册了一个新账号,购买了高达49966 元商品。实质上并非本人的购买行为。其实,该商城风控部门利用其风控体系在支付的那一刻已触发预警。接到预警后,风控负责人快速安排对这一订单的拦截,同时安排发货以进一步锁定嫌疑人,最终帮助挽回损失。
