Secure HIC System Based on WWW

Abstract

Words Wide Web(WWW) is a total solution for multi-media data transmission on Internet. Because of its characteristics like ease of use, support for multi-media data and good graphic user interface, WWW has extended to cover all applications. The HIC system is a information sharing system on WWW. It’s main function is to provide information sharing mechanism among its users by file uploading and downloading. Since the transmitted data is a private or secrete information, it is important to protect the information from unauthorized users. The secure HIC system uses conventional cryptographic methods to protect the transmitted data. It supports the encryption and authentication of data. For encryption of data IDEA(International Data Encryption Algorithm) is used and for authentication mechanism MDS hash function is used. Since secure HIC system is used by its user group, conventional crypto system is efficient in managing its user’s secure interactions. However, conventional crypto system can brings about some critical problems on sharing of same key and data transmission between client and server. For example the risk of key exposure and the difficulty of key sharing mechanism. To solve these problems, the secure HIC system provides secure key sharing mechanism and management policies. As the commercial use of WWW increases, security mechanisms like the secure HIC will become widely popular.
