Abstract |
The objective of this paper is to emphasize the need for an effective security model and its implementation for a distributed medical information system. Web services is meant to share the resources globally, irrespective of the network and platform on which the application is running. This is achievable through a communication protocol called Simple Object Access Protocol (SOAP). This paper hence considers medical services connected through a SOAP-RPC based communication network. SOAP protocol does not specify the security of the web transactions it carries and so it is the responsibility of any application to take care of the safety of its critical data being transmitted. The adaptive nature of this proposed security model not only considers the protection of an entire web transaction, but also customizes the safety of any fragment of the transaction. Confidentiality of information is achieved through the Advanced Encryption Standard (AES) mechanism whereas authenticity of the user and data integrity is verified using the digital signature embedded as part of the SOAP document. The authorization of the clients is also checked based on the security policy adopted by the application. The model uses a role-based access policy assigned to each legitimate user. This paper analyzes a possible and alternate security mechanism to Secure Socket Layer (SSL) technology for distributed applications. |
