  Abstract

The emergence of practical quantum computers poses a significant threat to the most popular public key cryptosystems in current use. In order to cope with this problem, NIST has been standardizing post-quantum cryptography algorithms since 2017. The LDPC code, which is widely used as a representative error correction code for communication systems, has been proposed as a code to be applied to the code-based cryptography in BIKE and LEDAcrypt, two candidates for NIST standardization. In code-based cryptosystems, decoding performance is significant because it determines the security level of the cryptosystems. In this paper, we introduce the proposed decoding techniques in the LDPC code-based post quantum cryptosystems to prepare for the upcoming quantum computing era.
