Security analysis of the W-OTS signature scheme: Updating security bounds
M. A. Kudinov, E. O. Kiktenko, A. K. Fedorov
In this work, we discuss in detail a flaw in the original security proof of the W-OTS variant of the Winternitz one-time signature scheme, which is an important component for…
Advanced attribute-based protocol based on the modified secret sharing scheme
M. A. Kudinov, A. A. Chilikov, E. O. Kiktenko +1
We construct a new protocol for attribute-based encryption with the use of the modification of the standard secret sharing scheme. In the suggested modification of the secret shari…
Proof-of-forgery for hash-based signatures
E. O. Kiktenko, M. A. Kudinov, A. A. Bulychev +1
In the present work, a peculiar property of hash-based signatures allowing detection of their forgery event is explored. This property relies on the fact that a successful forgery…
Detecting brute-force attacks on cryptocurrency wallets
E. O. Kiktenko, M. A. Kudinov, A. K. Fedorov
Blockchain is a distributed ledger, which is protected against malicious modifications by means of cryptographic tools, e.g. digital signatures and hash functions. One of the most…
SPHINCS post-quantum digital signature scheme with Streebog hash function
E. O. Kiktenko, A. A. Bulychev, P. A. Karagodin +3
Many commonly used public key cryptosystems will become insecure once a scalable quantum computer is built. New cryptographic schemes that can guarantee protection against attacks…
