Which protocol provides more security for email

Exchange enterprise mailbox has a high degree of security.

Answer]: Transport Layer Security (TLS) and its predecessor, Secure Socket Layer (SSL), are security protocols designed to provide security and data integrity assurance for Internet communications.

The Hypertext Transfer Security Protocol https is a transport protocol for secure communication over a computer network.

PGP is generally used when enterprise resource planning (ERP) software is connected to the banking system to prevent information from being deleted or stolen during transmission, thereby reducing the risk of trade secret leakage and fraud. At the same time, the email also supports PGP encryption.

MIME is extensible and security agnostic.

MIME is the multi-purpose Internet mail extension, which is the mail technical specification commonly followed by Internet email. Before the advent of MIME, the Internet electronic delay mail mainly follows the standard formulated by RFC 822, and the email is generally only used to transmit basic ASCII code text information, MIME has made a lot of expansion of the email specification on the basis of RFC 822, and introduced a new format specification and encoding method, with the support of MIME, images, sounds, animations and other binary codes can be easily delivered by email. The functionality of e-mail has been greatly enriched. At present, the e-mail used on the Internet basically follows the MIME specification.

The SET protocol is mainly used to ensure the security of emails. (a)

a.Wrong

b.It's good to be round correctly.

1. SET is the abbreviation of secure electronic transactions, which is an open, electronic money-based electronic payment protocol standard set up for the purpose of conducting ** transactions on the Internet.

2. The goal of SET is to ensure the safe transmission of information on the Internet, to ensure the mutual isolation of information of e-commerce participants, to solve the problem of multi-party authentication, to ensure the real-time nature of online transactions, to promote the compatibility and interoperability of software developed by different manufacturers, and to run on different hardware and operating system platforms.

3. The objects involved in the SET protocol specification include consumers, ** stores, acquiring banks, electronic money and certification centers (CAs), etc. The SET protocol mainly uses symmetric encryption, public key encryption, hashing algorithm, digital signature technology, and public key authority mechanism. The application of these technologies enables SET to guarantee the confidentiality, consistency and integrity of transaction data.

4. The authentication of merchants is realized, which provides consumers with the means to authenticate the identity of merchants, and at the same time promotes the compatibility of software developed by different manufacturers, and realizes the functions that can be interoperable on different hardware and operating system platforms. To sum up, SET has many advantages, so the SET credit card payment form represents the development direction of e-commerce payment and settlement.
