Abstract:
Physical Unclonable Functions (PUFs) have been increasingly used as an alternative to non-volatile memory for the storage of cryptographic secrets. Research on side channel and fault attacks with the goal of extracting these secrets has begun to gain interest but no fault injection attack targeting the necessary error correction within a PUF device has been shown so far. This work demonstrates one such attack on a hardware fuzzy commitment scheme implementation and thus shows a new potential att...     »
