Quantum-Inspired Cyber Threat Detection for Digital Signature Security
Egreen Quanta · Blockchain & Cybersecurity · Software
The empty field is tempting but the physics is graduate-level and the sponsor will judge it expertly — attempt this only with a team member who genuinely understands quantum information theory, otherwise the detection statistics will be wrong.
Data: Public/Open
What it actually is
Quantum computers will eventually break RSA and elliptic-curve signatures, so quantum digital signature protocols aim for security guaranteed by physics rather than by hard math. The ask is a framework that detects attacks — forgery, impersonation, replay, channel manipulation — against a teleportation-based quantum digital signature scheme, using quantum measurement statistics rather than any AI or machine learning.
What to build
A simulation of a teleportation-based quantum digital signature protocol with a threat-detection layer that, explicitly without any AI or ML, uses quantum principles — Pauli eigenstates, projective measurements and statistical analysis of measurement outcomes — to detect forgery, impersonation, replay attacks and quantum channel manipulation by computing forgery probabilities and verification accuracy from measurement statistics, evaluated through attack simulations that show detection rates and false-accept rates while preserving the protocol's information-theoretic security guarantees.
Smallest thing that wins the room
Run the signature protocol simulation under a forgery attack and show the measurement-statistics detector flagging it by the shift in the measurement outcome distribution, with the computed forgery probability crossing the detection threshold, contrasted against a legitimate signature that passes.
How crowded this one gets
A guess, projected from the 2025 statements — the last year where both the submission counts and the winners were published.
Quieter than 91% of the 226 · #22 of 226 by expected field
Few teams are likely to go here. The best odds on the board come from statements like this.
Why: company-sponsored statements drew the smallest fields of all.
This is a guess, not a fact
Nobody has published 2026’s numbers yet. This is an analysed estimate from last year’s pattern, so please do not take it as the truth — check the live counter on the SIH portal before you decide anything. The range covers the middle half of likely outcomes, so one statement in two lands outside it. Entry closes at 500 ideas per statement, so no range goes past that — a statement that reaches the cap fills and shuts rather than drawing an unlimited crowd. The model reads only three things a team can see before choosing — software or hardware, the theme, and what kind of body posted it — and those explain about a quarter of the variation in last year’s field sizes (R² 0.25 on held-out statements). Trust the band more than the number, and the ordering more than either. It cannot see how good your idea is, which is the part that actually decides it.
The scores
The number is the shorthand. The line under it is the reason.
Acceptance potential
2/5The field will be almost empty because the physics is intimidating, but that same barrier makes it a poor bet — without a team member who genuinely understands quantum information theory, the detection statistics will be wrong in ways an Egreen Quanta judge, who chose this topic, will immediately identify.
Feasibility
2/5This requires genuine understanding of quantum information theory — teleportation protocols, Pauli measurement statistics and information-theoretic security proofs — which is graduate-level physics rather than something a typical student team can pick up alongside the build, even though the simulation itself runs in Qiskit.
Innovation scope
3/5The description prescribes the protocol family, the mathematical tools and the explicit exclusion of AI, so the approach is heavily constrained and your room is in the detection statistics and attack modelling.
Clarity
4/5The objectives are numbered, the protocol and mathematical methods are named, the attacks to detect are listed, and AI is explicitly excluded, so the requirement is precise — but precise in a way that demands deep domain knowledge to even parse.
Effort
HeavySimulating the protocol correctly and building a statistically sound detection layer is focused work, but the conceptual prerequisites make every step slower than the code length suggests.
Demo-ability
MediumA measurement distribution shifting under attack is a clean result to a physics-literate judge, but it is abstract and needs the protocol explained before it means anything to a general audience.
In its favour
- Green flag: Qiskit simulates the teleportation and measurement operations, so the quantum mechanics is executable without hardware
- Green flag: The explicit exclusion of AI focuses the work on genuine quantum-statistical methods rather than bolting on a classifier
- Green flag: The field will be extremely thin because almost no team will attempt quantum cryptography
- Green flag: The topic is precisely the sponsor's specialty, so a correct submission will be deeply appreciated
Against it
- Red flag: Teleportation-based quantum digital signatures and their security proofs are graduate-level quantum information theory, and getting the detection statistics subtly wrong produces confident nonsense
- Red flag: The sponsor chose this topic and will evaluate it with domain expertise, so conceptual errors that a general judge would miss are exposed immediately
- Red flag: The subject is abstract enough that a general-audience demo lands poorly without significant explanation
- Red flag: Without a genuine quantum-information background on the team, this is not realistically attemptable
