Caffeinated Petručeņa Quantum Key Distribution • Software Architecture • Confidential Computing

Hi! I’m Krišjānis Petručeņa. I work at the Institute of Mathematics and Computer Science, University of Latvia (IMCS, UL) as a research assistant. I spend my time frustrated by quantum-safe communication, software architecture, and confidential computing. As a hobby, I host an archive of latvian informatics olympiad problems (LIO) at programme.lv.

Problems with ETSI GS QKD 014 v1.1.1

Quantum Key Delivery (QKD) can detect eavesdropping on a communication channel. ETSI GS QKD 014 helped standardize QKD key delivery northbound API, but its model is too narrow. This post argues that the standard underspecifies SAE identity binding, authorization, key sizing, bulk delivery, and buffering.
