초록

The concept of the Internet of Things (IoT) enables physical objects or things to be virtually accessible forboth consuming and providing services. Undue access from irresponsible activities becomes an interestingissue to address. Maintenance of data integrity and privacy of objects is important from the perspective ofsecurity. Privacy can be achieved through various techniques: password authentication, cryptography, and theuse of mathematical models to assess the level of security of other objects. Individual methods like these areless effective in increasing the security aspect. Comprehensive security schemes such as the use of frameworksare considered better, regardless of the framework model used, whether centralized, semi-centralized, ordistributed ones. In this paper, we propose a new semi-centralized security framework that aims to improveprivacy in IoT using the parameters of trust and reputation. A new algorithm to elect a reputationcoordinator, i.e., ConTrust Manager is proposed in this framework. This framework allows each object todetermine other objects that are considered trusted before the communication process is implemented. Evaluation of the proposed framework was done through simulation, which shows that the framework can beused as an alternative solution for improving security in the IoT.

Abstract

The concept of the Internet of Things (IoT) enables physical objects or things to be virtually accessible forboth consuming and providing services. Undue access from irresponsible activities becomes an interestingissue to address. Maintenance of data integrity and privacy of objects is important from the perspective ofsecurity. Privacy can be achieved through various techniques: password authentication, cryptography, and theuse of mathematical models to assess the level of security of other objects. Individual methods like these areless effective in increasing the security aspect. Comprehensive security schemes such as the use of frameworksare considered better, regardless of the framework model used, whether centralized, semi-centralized, ordistributed ones. In this paper, we propose a new semi-centralized security framework that aims to improveprivacy in IoT using the parameters of trust and reputation. A new algorithm to elect a reputationcoordinator, i.e., ConTrust Manager is proposed in this framework. This framework allows each object todetermine other objects that are considered trusted before the communication process is implemented. Evaluation of the proposed framework was done through simulation, which shows that the framework can beused as an alternative solution for improving security in the IoT.
