Hamming-code based fault detection design methodology for block ciphers
Description
Fault injection, in particular Differential Fault
Analysis (DFA), has become one of the main methods for
exploiting vulnerabilities into the block ciphers currently used
in a multitude of applications. In order to minimize this type
of vulnerabilities, several mechanisms have been proposed to
detect this type of attacks. However, these mechanisms can have
a significant cost or not adequately cover the implementations
against fault attacks. In this paper a novel approach is proposed,
consisting in generating the signatures of the internal state using
a Hamming code. This allows to cover a larger amount of faults
allowing to detect even or odd bit changes, as well as multibit
and multi-byte changes, the ones that make ciphers more
vulnerable to DFA attacks. As case of study, this approach
has been applied to the Advanced Encryption Standard (AES)
block cipher implemented on FPGA using T-boxes. The results
suggest a higher fault coverage with an overhead of 16% of
resource consumption and without any penalty in the frequency
degradation.
