In this paper we show several quantum chosen-plaintext attacks (qCPAs) on contracting
Feistel structures. In the classical setting, ad-branch r-round contracting Feistel structure can …

Simon's algorithm is the first example of a quantum algorithm exponentially faster than any
classical algorithm, and has many applications in cryptanalysis. While these quantum …

The paper provides an overview of the main approaches to the construction of post-quantum
cryptographic systems that are currently used. The area of lattice-based cryptography is …

Generalized Feistel networks are important components of symmetric ciphers, and detailed
security evaluations in the quantum setting remain to be explored. In this paper, based on …

In this paper, we study the quantum security of block ciphers based on Simon's period-
finding quantum algorithm. We explored the relations between periodic functions and …
