Abstract

As the computational technology using quantum computing has been developed, several threats on cryptographic systemsare recently increasing. Therefore, many researches on post-quantum cryptosystems which can withstand the analysis attacksusing quantum computers are actively underway. Nevertheless, the lattice-based NTRU system, one of the post-quantumcryptosystems, is pointed out that it may be vulnerable to the fault injection attack which uses the weakness ofimplementation of NTRU. In this paper, we investigate the fault injection attacks and their previous countermeasures on theNTRU signature system and propose a secure and efficient countermeasure to defeat it. As a simulation result, the proposedcountermeasure has high fault detection ratio and low implementation costs.
