What is the most powerful secure electronic transaction protocol currently?

The current secure electronic transaction protocol with strong functions is: SET protocol. The SET protocol itself is relatively complex, has a strict design, and has high security. It can ensure the confidentiality, authenticity, integrity and non-repudiation of information transmission; the SET protocol ensures the security of online shopping using credit cards on an open network.

While e-commerce provides opportunities and convenience, it also faces one of the biggest challenges, namely transaction security. In an online shopping environment, cardholders hope to keep their account information confidential during transactions to prevent it from being misappropriated; merchants hope that customer orders cannot be repudiated, and during the transaction process, all parties to the transaction hope to verify The identity of other parties to prevent being deceived.

In response to this situation, the two major credit card organizations in the United States, Visa and MasterCard, and many international technology institutions have jointly formulated security standards for online transactions based on bank cards that are applied to the Internet. This is "Secure Electronic Transaction" (SET). It uses public key cryptography and the X.509 digital certificate standard, and is mainly used to ensure the security of online shopping information.

The SET protocol is designed based on the credit card payment model on B2C. It ensures the security of online shopping using credit cards on the open network. SET is mainly designed to solve credit card transactions between users, merchants, and banks. It has various advantages such as ensuring the integrity of transaction data and non-repudiation of transactions. Therefore, it has become the currently recognized international standard for online credit card transactions. standard.

Since SET provides authentication between consumers, merchants and banks, it ensures the security, complete reliability and non-repudiation of transaction data, especially ensuring that consumers’ bank card numbers are not exposed to Merchants and other advantages. Therefore, by 2012, it became the recognized international security standard for online credit/debit card transactions.

SET (Secure Electronic Transaction) secure electronic transaction protocol is mainly used to ensure the security of payment information in the B to C model. The SET protocol itself is relatively complex, has a strict design, and is highly secure. It can ensure the confidentiality, authenticity, integrity, and non-repudiation of information transmission. The SET protocol is a typical implementation under the PKI framework and is constantly being upgraded and improved. For example, SET 2.0 will support debit card electronic transactions.
