An Efficient Two-Factor Authentication Scheme Based on the Merkle Tree
Sensors, 2020 The Time-based One-Time Password (TOTP) algorithm is commonly used for two-factor authentication. In this algorithm, a shared secret is used to derive a One-Time Password (OTP). However, in TOTP, the client and the server need to agree on a shared secret

Secure big data collection and processing: Framework, means and opportunities
Journal of the Royal Statistical Society: Series A (Statistics in Society), Volume 185, Issue 4, Page 1541-1559, October 2022., 2022 Abstract Statistical disclosure control is important for the dissemination of statistical outputs. There is an increasing need for greater confidentiality protection during data collection and processing by National Statistical Offices. In particular, various transactions and remote sensing signals are examples of useful but very detailed big data that

Covert Channels in One-Time Passwords Based on Hash Chains [PDF]
Proceedings of the European Interdisciplinary Cybersecurity Conference, 2020 We present a covert channel between two network devices where one authenticates itself with Lamport's one-time passwords based on a cryptographic hash function. Our channel enables plausible deniability. We also present countermeasures to detect the presence of such a covert channel, which are non-trivial because hash values are randomly looking binary

Novel self-renewal hash chain scheme based on (t,n) threshold and division tree
Tongxin xuebao, 2013 The introduction of renewal hash chain overcame resource-constrained defect in traditional hash chains,but the existing renewable schemes had still held unsatisfactory performance especially on security and complexity.The definitions of repetition ...
