Resum

Side-channel analysis (SCA) is a powerful tool to extract (cryptographic) secrets by observing physical properties (power consumption, EM, ...) of a target device. After an intro to SCA and related methods, we demonstrate the practical relevance of SCA with two case studies: First, we show how SCA can be used to circumvent the IP protection (bitstream encryption) of FPGAs. In a similar way, AES keys of one-time password tokens can be extracted, allowing an attacker to steal digital identities. Outline: 1) Introduction to Implementation Attacks 2) Side-Channel Analysis in a Nutshell 3) Breaking the Bitstream Encryption Scheme of FPGAs 4) SCA of the Yubikey 2 One-Time Password Token 5) Lessons Learned
