Fault attack countermeasures can be implemented by storing or computing sensitive data in redundant form, such that the faulty data can be detected and restored. We present a class of lightweight, portable software countermeasures for block ciphers. Our technique is based on redundant bit-slicing, and it is able to detect faults in the execution of a single(More)
Fault attacks are a known serious threat to embedded software security. We propose FAME, a low-cost and flexible approach to defend embedded software against fault attacks. FAME offers a combination of fault detection in hardware and fault response in software. A hardware fault detection unit continuously monitors the system status. When a fault injection(More)
