Discuss the security issues of Bluetooth Low Energy (BLE).
Which of BLE and WiFi WPA2 is security wise most suited for an embedded system?
BLE (Bluetooth Low Energy) uses128-bit encryption which is less than WI-FI which uses 256-bit encryption, which affects the security. Also, initially, BLE had security issues that let the third party have access to the exchange between two devices which was later on solved by AES-CCM cryptography which leads to data encryption. But still, the decryption was possible by the hackers. In spite of the fact that BLE also offers a 6-digit passkey method, but it still can be accessed by the hackers during the typing of passkey by the user which leads to security issues.
Wifi WPA2 is security-wise most suitable for an embedded system because it uses 256-bit encryption as it is more strong than 128-bit encryption of BLE which enhances the security. Also WPA2 can be more secured by using passwords.
