ESES/Cipher: A Design of XML Encryption System

摘要

In these several years, Electronic Commerce has been rapidly expanding in many fields such as B2B, B2C and so on. However, there exist several problems preventing the electronic commerce from spreading more widely and being used more frequently. One of these problems is a security problem, which brings that most e-commerce site visitors are reluctant to shop online. ESES/Cipher, which will be introduced in this paper, can be one approach to solve the problem. ESES/Cipher is a subsystem of ESES (ETRI Secure E-commerce Service) that has implemented to support security services such as authentication, integrity and confidentiality for Electronic Document Interchange. And ESES/Cipher provides a process for encrypting/ decrypting a digital content and an XML syntax used to represent the encrypted content and information that enables an intended recipient to decrypt it. It also provides syntax of partial encryption and group access to it using a conference key.
