This work presents the networked home environment from the security point of view. Threats, technologies and the special characteristics of the users are examined. 'Common Criteria' is used in this thesis as a security evaluation criterion to construct a protection profile for the software distribution platform of a networked home environment. 'Protection profile' describes the target of the evaluation - the networked home environment and its security environment, along with access control and information flow policies. This environment sets the context for the security requirements that are established as a result of this thesis to counter the threats that are also identified in the protection profile as a part of the security environment. Java is a relatively promising platform for the networked software because of its security model, which has evolved since the first versions of Java. Java's application programming interfaces provide support for widely used cryptographic techniques and public key infrastructure frameworks, including the X.509 authentication framework. Java's security features are applied to the software distribution platform developed at VTT Electronics. The security framework for the platform is developed and presented in this work. 'Home', as a distributed computing environment, presents many new issues when compared to typical corporate office networks. Users are very heterogeneous and their needs differ from one to another. The requirements specification must be done with care, and by using knowledge of the system and existing security techniques to develop a system that provides adequate confidentiality, integrity and availability for its users.
