Smart-Lock Security Re-engineered using Cryptography and Steganography
This addresses security issues for IoT smart lock users, but it appears incremental as it builds on existing cryptographic and steganographic methods.
The paper tackled the vulnerability of Bluetooth Low Energy (BLE) to Man-in-the-Middle attacks in smart locks by proposing a solution combining image steganography and cryptography, resulting in increased security levels.
After the rise of E-commerce, social media and messenger bots, rapid developments have been made in the field of connecting things, gadgets, and devices, i.e, the Internet of Things (IoT). In the fast-paced lifestyle, it is very difficult to maintain multiple keys for traditional mechanical locks. Electromagnetic smart locks are a possible solution to this problem. To connect a smart lock with a key, Bluetooth Low Energy (BLE) protocol can be used. BLE protocol is vulnerable to Man-in-the-Middle (MITM) attack. Ensuring security over BLE is an ongoing challenge. This paper aims to analyze the MITM vulnerability of BLE and develop a possible solution for designing smart-locks with an increased level of security. The observation shows that the combination of Image Steganography and Cryptography helps to overcome the vulnerabilities of BLE protocol.
