    RESEARCH QUESTION

     
    The aim of the research is to construct a secure model for implementing OAuth 2.0.

    In other words to answer the question:

    What is a secure model
    for implementing OAuth 2.0 like?

    WHAT IS AUTHORIZATION?

    SITUATION NOW

    • A growing amount of data is stored in the cloud and the number of web services is soaring. 
    • This has created a need for users to authorize third party applications to access their resources.

    AUTHORIZATION


    • The purpose of authorization is to let users allow third party applications access their resources.

    • The OAuth 2.0 authorization framework offers an open and standardized protocol for authorization.

    • OAuth 2.0 is used by e.g. Google, Microsoft and Facebook.

    AN EXAMPLE: FACEBOOK CONNECT

    • Facebook Connect is a good example of an implementation of OAuth 2.0: An application is allowed to access e.g. the users email address and posts.


    HOW DOES OAuth 2.0 

    WORK?

    Research method
    and execution 
    of the study  

    RESEARCH METHOD



    The research will take a form of a design-science research study.

    EXECUTION OF THE STUDY


        1. With the help of current literature the features of a secure OAuth 2.0 implementation are identified

        2. Available libraries for implementing these features are assessed.

        3. OAuth 2.0 is implemented.

        4. The security of the resulting implementation is extensively tested and the test results analyzed.
