Smart-Lock Security Re-engineered Using Cryptography and Steganography [chapter]

Chaitanya Bapat, Ganesh Baleri, Shivani Inamdar, Anant V. Nimkar
2017 Communications in Computer and Information Science  
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.  ...  The observation shows that the combination of Image Steganography and Cryptography helps to overcome the vulnerabilities of BLE protocol.  ...  Here, as the public key used for encryption was attackers public key, decryption needs to be carried out using attackers private key.  ...
