TitleDistinguished Guest Lecture on “Cybersecurity for IoT Applications using Attribute-Based Access Control”
Details

BITES in association with Department of Computer Applications, PES University, Bangalore organised a Distinguished Guest Lecture on "Cybersecurity for IoT Applications using Attribute-Based Access Control" by Prof. Manimaran Govindarasu, Department of Electrical and Computer Engineering, Iowa State University on 1st August 2017. The event started with an introduction of Prof. Manimaran by dr. K N B Murthy, Vice chancellor of PESU. Prof. Manimram spoke about the Access Control of Cybersecurity for IoT Applications using attributes. The lecture was attended by around 60 faculty and students of PESU, East West College of Engineering and BMS College of Engineering.


Given the vast opportunities the IoT promises to provide, it is widely being adopted worldwide in diverse application domains. However, IoT’s “access by anybody from anywhere” concept makes it prone to numerous security challenges. Although data security is studied at various levels of IoT architecture, breach of data security due to internal parties has not received as much attention as that caused by external parties. When an organization with people spread across multiple levels of hierarchies with multiple roles adopts IoT, the approach of providing uniform access of the data to everyone is not a valid one. Past research has extensively investigated various Access Control techniques like Role Based Access Control (RBAC), Identity Based Access Control (IBAC), Attribute Based Access Control (ABAC) and other variations to address the above issue. While ABAC meets the needs of the growing amount of subjects and objects in an IoT environment, when implemented as an encryption algorithm (ABE), it does not cater to the IoT RDBMS applications. Also, given the query processing over huge encrypted dataset on the Cloud and the communication between the Cloud and the end-user, latency issues are highly prevalent in IoT applications. In this talk, he first presented an Attribute Based Access Control (ABAC) mechanism for the IoT data on the Cloud in order to provide a fine-grained access control in an organization. He presented an Attribute Based Cache Consistency (ABCC) technique that tailored Cache Invalidation according to the users’ attributes to cater to the latency as well as criticality needs of end-users. Finally, he discussed the application of these techniques to healthcare data and present performance evaluation using an IoT testbed environment.
