Enterprise Security E-mail Research And Application

With the development of high-speed Internet business, people using the Internet as a means of exchange of information has become increasingly popular ,network information security problems are more and more concerned. In order to solve network security issues, all countries in the world has formed several solutions through many year's research, but the most mature technology, and the most widely used solution is public key infrastructure (Public Key Infrastructure) PKI Technology.CNC enterprise security e-mail product is a product based on PKI / CA technology and digital certificates as Netcom entity that can provide users with comprehensive security e-mail product research and development. This product is effective to avoid a threat to the e-mail security factors for enterprise network, it realizes the network authentication, ensures confidentiality, integrity and non-repudiation about email information, CA Netcom is embodied e-mail authentication technology perfectly in mail system. It integrates all the benefits of technology of PKI / CA:1) The realization of the network user authentication;2) The realization of confidentiality for data transmission network based on public key encryption technology;3) The realization of function of integrity for verification of information in the use of digital signature technology;4) The realization of non-repudiation information based on the user's e-signatures.PKI is an encryption key management platform which follows established standards, and it is also a management system which delivers password services of encryption and digital signatures and required password certificate. PKI is consisted by basic components such as public key cryptography and digital certificates, the certification agency (CA) and related public-key security policies ect. Ii contains two password-core technologies: First,digital signature,ensure the integrity and non-repudiation technology for information transmitting ,Second , data encryption, user encrypt the information in the use of public key, they take care of decryption Key themselves ,but not transmitted on the Internet, so that it avoids theft key . CA (Certificate Authority) is the identity authentication system; it can carry out the legality of online identity check. PKI / CA is a complete security concept, it has recognized safety standards for "authentication, access control, data confidentiality, information integrity, non-repudiation" . Under normal circumstances, CA and PKI technology will be applied together .at present ,PKI / CA is the most effective way to ensure Internet security technology.CNC enterprise security e-mail product based on human design allows users to use the process with the full experience of its convenience , fast and safety:1) Users log on by use of digital certificates , do not have to enter a user name, password and check image code, just click the mouse. need not worry about passwords remember or leaking password.2) Configuration of the authentication server in the system design so that users do not have to look for each other's public key encryption painstakingly.3) Digital certificates with different storage medium in the systems to meet the needs of different users.We have developed security e-mail products with the above advantages, not only to address the e-mail on the Internet in an open transfer of security issues, but also to increase the convenience of users, so it is received the good appraisal by the users once launched.CNC enterprise security e-mail product is typical applications for CA Netcom electronic authentication in system design, not only considers security point, but also takes into account the user's convenience. In order to facilitate the operation of the user, the system sets up certificate authentication server. Authentication server building, one hand eliminate the process of sender coming to the LDAP server to find the public key, before sending e-mail security to the recipient server up to find the recipient's ,on the other hand not only alleviate the burden, but also bring the convenience to users.CA Center produce a digital certificate, digital certificates, including user name, user-mail address, ID number, and other basic user information for each user. when users log on e-mail system, e-mail system through a system of signatures to verify the of the user's identification. In the process of Certificate production, the system will automatically store user certificates to the certificate of authentication specified in the database server, authentication server and mail server interact data through standard Web Service way. When the user needs to send signed and encrypted e-mail, initiated by the mail server to find the recipient's public key request, authentication server, will be received by the recipient's public key to send e-mail server, mail server accompanied with the user complete and sign encryption process.Enterprise security e-mail product is the main application to customer base such as government agencies, enterprises and institutions, e-mail provider, and with business expands, it will extend to the public user gradually. Government agencies and enterprises and institutions send and receive all kinds of confidential documents, financial statements, legal documents, design projects or tenders, and so on through regular e-mail, the data information on the units is critical, in the event of a leak or other security issues , and its negative impact is estimated immeasurable ,so it is urgent for these unit in the need of these products ,which has provided us with an excellent entry point for the market, but it also apply widely to other enterprises and institutions.With the public's awareness of the importance of safety messages deeply, we will gradually expand the application of security e-mail product range, public users market will become an important market growth for the security e-mail products in the future. Enterprise security e-mail is the important step for the telecommunications industry transformation in the future development of the business, though currently still in the early stage we believe that the enterprise security business mail will dull the flavor of the new communications market after a period of marketing cultivation.
