On the Issue of Using “Useful” Tasks for Proof of Works in Blockchain
Моделирование и анализ информационных систем, 2019 This paper is a logical continuation of the paper about possible approaches to solving the “Useful Proof-of-work for blockchains” problem. We suggest some alternative ways for searching useful tasks for Proof-of-work systems.

Updatable Hash Proof System and Its Applications
, 2015 To tackle with physical attacks to real world cryptosystems, leakage resilient cryptography was developed. In this setting, the adversary is allowed to have access to the internal state of a cryptographic system, thus violates the black-box reduction used in cryptography.
