Unifying Kleptographic Attacks can replace individual backdoors embedded into protocols for proving knowledge of a discrete logarithm (. the Schnorr and Girault protocols), protocols for proving knowledge of an .-root (. the Fiat-Shamir and Guillou-Quisquater protocols), protocols for proving knowledge of a discrete logarithm re

Revisiting Deniability in Quantum Key Exchanged Beaver, it is argued that QKE is not necessarily deniable due to an eavesdropping attack that limits key equivocation. We provide more insight into the nature of this attack and how it extends to other constructions such as QKE obtained from uncloneable encryption. We then adopt the framework for

On Security Analysis of Generic Dynamic Authenticated Group Key Exchange Dynamic AGKE allows for very efficient group membership changes (join, leave, merge and partition, etc.) during protocol executions. In this paper, a security model is developed for generic dynamic AGKE to cover more active attacks than previous similar models (such as leakage of ephemeral secret k

A Blockchain-Assisted Hash-Based Signature Scheme model somewhat. We postulate a set of design requirements, discuss some approaches and their practicality, and finally reach a forward-secure scheme with only modest trust assumptions, achieved by employing the concepts of . and .. The concepts of blockchain authenticated data structures and the pr

The Fiat-Shamir Zoo: Relating the Security of Different Signature Variantsetimes to one variant, sometimes to another. We systematically study three variants that we call the challenge (signature is challenge and response), commit (signature is commitment and response), and transcript (signature is challenge, commitment and response) variants. Our framework captures the v

Verifiable Light-Weight Monitoring for Certificate Transparency Logsor is to observe each and every log entry, looking for suspicious certificates that interest the entity running the monitor. While anyone can run a monitor, it requires continuous operation and copies of the logs to be inspected. This has lead to the emergence of monitoring as-a-service: a trusted t

What You Can Change and What You Can’t: Human Experience in Computer Network Defenses alone on technology, but also on people. Understanding how people experience these environments is an essential component toward achieving optimal functioning. This paper describes a qualitative research study on the human experience of working in these environments. Using Grounded Theory, a psycho
