The Study Of Authentication Mechanism For Enterprise Private Cloud File Encryption System

With the rapid development and popularization of the network technology, cloud computing technology is being more and more popular with universities, enterprises and research institutions.Cloud computing is a new data resource delivery and usage patterns. It’s refers to the network to obtain the resources needed by way of required, dynamic and scalable. Cloud service is based on the cloud computing model to provide on-demand personalized service mode. According to the enterprises requirements of information security, enterprises generally use the private cloud architecture to build their own cloud services. More and more enterprises want to have their own private cloud computing center or the data center to optimize operation and save money. However, due to the development of cloud computing in the security technology is not yet mature and limits its application in enterprises. There are a number of security issues need to be considered in the framework of enterprise private cloud platform. Especially the authentication security problem of the enterprise private cloud encryption file system and authentication security is the precondition of safe operation of enterprise private cloud, which is directly related to the immediate interests of enterprises, and also related to the development and application of private clouds in the future. Therefore, it is important to study private cloud authentication mechanism.In this paper we carried on a deep research to the main file encryption system and Combination the overall structure of the private cloud computing system, Put forward the private cloud file encryption system based on e Cryptfs.And in view of the current enterprise private cloud encryption file system is lower authentication efficiency. After studied the characteristics of aggregate signature in depth.,an authentication scheme of efficient aggregate signature was introduced into the authentication of enterprise private cloud file system encryption. After analysis, this scheme has high efficiency and high security compared with the traditional scheme. In order to protect sensitive company data were not to leak and further improve the security of authentication, a secure and efficient certificateless tripartite key agreement protocols was introduced into the authentication of the enterprise private cloud file system encryption. Authentication scheme based on the certificateless tripartite key agreement protocols enterprise privatecloud file encryption system is implemented. The scheme achieves mutual authentication among three entities of client, private cloud gateway and file encryption server. The analysis results show that this scheme high security compared with scheme of aggregate signature and has high efficiency compared with the traditional scheme. This system is running on the system environment of ubuntu10.04. This solution achieved the security of storage resource by using e Cryptfs file system non-interactively and solved the main security and efficiency problems that private cloud system face in large scale application environment.
