Title:
Towards Side-Channel Secure Firmware Updates - A Minimalist Anomaly Detection Approach 
Pages contribution:
16 pages 
Abstract:
Side-channel attacks represent a serious threat to the security of encrypted firmware updates: if the secret key is leaked, then the firmware is exposed and can be replaced by malicious code or be stolen. In this work, we show how simple anomaly detection measures can effectively increase the security of encrypted firmware updates at minimum cost. Our method is based on the simple observation that firmware payloads have a specific structure (machine code), which can be easily verified at run...    »
