Hardware Implementation of a Polar Code-based Public Key Cryptosystem. (arXiv:2212.13421v1 [cs.CR])

In recent years, there have been many studies on quantum computing and the
construction of quantum computers which are capable of breaking conventional
number theory-based public key cryptosystems. Therefore, in the not-too-distant
future, we need the public key cryptosystems that withstand against the attacks
executed by quantum computers, so-called post-quantum cryptosystems. A public
key cryptosystem based on polar codes (PKC-PC) has recently been introduced
whose security depends on the difficulty of solving the general decoding
problem of polar code. In …
