Understanding Quantum-Safe Solutions: Navigating the Future of Cybersecurity
In our ongoing blog series addressing quantum threats, we previously examined how government regulations influence the availability of Post-Quantum Computing (PQC) products. As various stakeholders prepare for advancements in PQC, concerns about Q-Day and Harvest Now, Decrypt Later (HNDL) cyberattacks loom. This article delves into current quantum-safe solutions and assesses the potential of Quantum Key Distribution (QKD), a developing technology poised to bridge contemporary cybersecurity practices and a future fortified against quantum threats.
Current Landscape of Quantum-Safe Solutions
The imminent threat posed by quantum computing has prompted proactive measures from technological enterprises, regulatory bodies, and governmental organizations alike. Cisco emerged as a frontrunner in establishing standard protocol for securing networks against quantum vulnerabilities. Our journey began with efforts to implement quantum-safe hardware secure boot mechanisms before advancing towards robust network transport protocols designed with security in mind.
The initial step toward secure boot was marked by Cisco’s introduction of the LDWM signature scheme, which debuted in 2013 through research by McGrew & Curcio. This innovation provides asymmetric authentication that sidesteps complex large integer math requirements. Shortly after its introduction, Cisco integrated LDWM-based secure boot into its hardware products. In 2019, thought leaders at Cisco including D. McGrew, M. Curcio, and S. Fluhrer unveiled the Leighton-Micali Signature (LMS) hash-based digital signature framework which utilizes cryptographic hash functions to create irrefutable digital signatures; this was acknowledged in NSA’s CNSA 2.0 guidelines discussed in prior articles concerning cryptography’s evolution post-quantum era.
The Convergence of QKD Technology
Cisco subsequently shifted focus towards developing network transport protocols that are resilient against quantum vulnerabilities through integration with QKD—an innovative method for securely distributing cryptographic keys using fiber optic properties. By employing photons for key exchange processes, it becomes feasible to confirm that no unauthorized interceptions or alterations have occurred during transmission sessions—a concept dating back several decades but recently gaining traction among numerous vendors who have begun deploying QKD systems.
For clarity’s sake throughout this discussion on key sharing technologies like QKD—even if some alternatives adopt different approaches—I will refer collectively to both hardware-specific implementations as well as software-driven “QKD-like” methodologies under one umbrella term “QKD.”
Difficulties arose when existing PQC algorithms had yet to receive standardization; hence Cisco concentrated on facilitating practical means for provisioning robust keys capable of replacing outdated methods vulnerable to future breaches—this brought about SKIP interface development initiated in 2017—a programming interface allowing devices access reliable keys via external key management systems such as those supported by QKD technologies utilized within popular transport frameworks including IPsec and MACsec aiming specifically against harvest-now decrypt-later cyber antics noted within IETF RFC 8784 procedural documents governing IPsec (IKEv2). Regrettably though there remains currently no recognized methodology relating these strategies directly pertaining specifically regarding MACsec applications.
Cisco has submitted documentation regarding SKIP specifications intending them earn an Informational RFC designation; promised usability across numerous devices facilitated industry-wide deployment options reflecting collaborative resilience shared amongst choices made today surrounding vendor support reaching roughly twelve affiliates employed alike integral functionalities shown below:
