Abstract:
Progressions in information and communication technologies (ICT) have led to the emergence of Internet of Things (IoT) and became one of the most powerful communication paradigms of the 21st century. A smart home or home automation technology is a combination of different IoT devices for comfort of human and security of homes through a remote interface using wireless transmission, thereby enabling users to control and monitor from a browser or smartphone. Therefore, access control must be strengthened in smart homes to protect the security and privacy aspects which can be achieved by implementing authentication and authorization mechanisms. The existing research on the subject suggests till now, multiple individual techniques like passwords, Pin code etc have been employed to cater for access control, however, the low processing and power requirement to these systems make these systems vulnerable to different type of attacks. A system needs to be crafted to enhance the element of security and user friendly usability in a smart home. Our purposed scheme, Authentication, Authorization, and Access Control using Voice Biometric in Smart Homes is an implementation of fingerprint and voice recognition together for authentication, authorization and access control. The main focus of this scheme is on access control in smart homes using voice biometric authentication along with mitigation of threats due to unauthorized access and non authentication of a user which includes Masquerade Attacks, Replay Attacks, Denial-of-Service Attacks, Spoofing attacks, Man-in-the-middle attacks and Impersonation attacks. We have used BAN logic analysis to validate the scheme‘s correctness. This scheme prevents system from replay attack by adding time stamp in request message. The performance analysis i-e computation cost and communication cost comparisons of our scheme with other schemes shows that efficiency of proposed scheme is more than other schemes.
