E-commerce (EC) of the security element and related technology
Will be able to confirm the digital signature is the sender. Digital signature can be achieved by the original message identification and non-repudiation. ISO/IECJTC1 in the drafting of the relevant international standards. The standard initial entitled \■ - Nang humble shuttlecock Cuan braided rattan cane. Intemet e-mail security protocol is the major means of information transmission, but also one of the main EC applications. But it does not have strong security measures. Internet Engineering Task Force (IEFT) for the expansion of e-mail security has been drafted the relevant specifications. q) PEMPEM is to enhance the secrecy of Internet e-mail a draft standard, it is the standard Internet e-mail format (see RFC822) adds encryption, authentication and key management functions. Allows the use of public key and private key encryption. And can support a variety of encryption tools. E-mail message for each packet header can be provided in a particular encryption algorithm, digital identification algorithms, hash functions and other security measures. PEM is transmitted through the Internet e-mail security,[link widoczny dla zalogowanych], the informal business standards. Details about it can see the Intemet Engineering Task Force published in RFC1421,[link widoczny dla zalogowanych], RFC1422, RFC143, and RFC1424 and other 4 files. PEM may be S / MIME and PEM-MIME specification replaced by (S / MlMES / MIME (secure multi-function expansion of Internet e-mail) is a multi-function described in RFC1521 Internet e-mail message based on the expansion to add a digital signature and A protocol encryption technology. MIME is the official expansion of Internet e-mail write stack ■ ■ ■-i-nEm ●-csi ∞ l dragonfly P ∞ Ⅸ U project standard format, but it did not provide any security services. s / MIME The purpose is defined in the MIME security services means the implementation of measures. S / MIME estate sector has become a widely accepted industry protocols, such as Microsoft, Netscape Corporation,[link widoczny dla zalogowanych], Novll Corporation, Lotus Corporation and so support the agreement. ⑨ PEM-MlME (MOSS ) MOSs (MIME Object Security Services) is a characteristic of both PEM and MIME were combined. ll return to solid rustic dance {curly security protocols ① SSLSSL (slot Layer Security) protocol developed by Netscape to study the security protocol to based on TCP / IP client / server applications the client and server authentication, data integrity and information confidentiality and other security measures. The agreement by the exchange of data in the application before the exchange of information to implement SSL on the initial handshake review of security features. In SSL handshake messages using DES, MD5 and other cryptographic techniques to achieve confidentiality and data integrity, and implementation using X.509 digital certificate authentication. The agreement has become the de facto industry standard. was Intemet and Intranet is widely used server products and client products. such as Netscape, Microsoft,[link widoczny dla zalogowanych], IBM, and other leading Internet / lntrnet network products company has been in the use of the protocol. In addition, Microsoft and Visa jointly study the development agencies a similar to the SSL protocol, which is PCT (Private Communications Technology). The agreement is only a small amount of SSL for the improvement. ② S-H1 a rPS-HTrP (secure hypertext transfer protocol) is the expansion of the Security H1'rP properties, increasing the security of the message. It is based on SSL technology. the application of the agreement provide integrity to the www,[link widoczny dla zalogowanych], identification, non-repudiation and confidentiality and other security measures. At present, the agreement was drafted by the lntemet Engineering Task Force Draft RFC. Security EDI is the most important part of the EC. is widely used in international exchange and automatic processing of business information and management information technology. UN / EDIFACT message is the only internationally accepted EDI standards. Intemet for EDI use has become a growing area of concern, to ensure the security of EDI as a major problem. the United Nations under the specialized UN / EDIFACT standards development organization --uN/EcE/wP4 (ie trade facilitation, the Working Group) was established in 1990 security Joint Working Group (UN-SJWG). to study the UN / EDIFACT standards implementation
