Arqit’s Approach to Quantum-Safe Cybersecurity Solutions

Arqit’s advantage

We minimise cyber risk while meeting customer needs in four key areas.

Strong

Validated and proven security, compliant with modern frameworks

Simple

Small footprint and drop-in integrations with major OEM vendors

Scalable

Cloud-based, dynamic, and on-demand, with robust endpoint management

Standards-based

Works alongside industry standards and available in FIPS mode

Strong

We promote strong, symmetric cryptography

Symmetric Key Agreement is Arqit’s unique technology for data security.

1. Symmetric keys are the most secure

They aren’t vulnerable to quantum methods and are the gold standard for government and enterprise.

2. Independent formal verification

Arqit’s protocols have been formally validated using the Tamarin prover method by the Surrey Centre for Cyber Security and assessed by ISE.

3. We address the vulnerabilities of PKI

We don’t rely on public/private keys and we operate with zero-trust principles, improving upon traditional failings of PKI.

Simple

Easy to integrate and highly performant

We use open interfaces to allow OEM partners to upgrade their solutions easily and without a performance penalty

	Arqit’s multi-tenanted cloud platform orchestrates agents and provides high-level management tools
	A single-core Arqit virtual agent sits within the endpoint’s network and handles communication with the cloud
	The vendor solution interacts with the agent only when needed using a standards-based interface

Our unique propositions

Quantum-safety today through our innovative and patented approach

Holistic approach most competitors focus on one postquantum method, whereas Arqit embraces many complementary methods

Doesn’t require post-quantum algorithms Arqit’s use of PQAs are limited to initial provisioning and customers can opt for symmetric-only provisioning

Strong, active authentication based on symmetric methods with forward secrecy that doesn’t rely on PKI

Software only no hardware required and can run as a virtualized network function

Easy to integrate through existing OEM partner integrations, standards-based interfaces, or directly through SDK

Arqit’s SKA process

Provisioning, authentication, and key agreement

Every endpoint is securely provisioned once with a “bootstrap” key

Endpoints strongly, mutually authenticate with perfect forward secrecy

Groups of endpoints agree quantum-safe symmetric keys using material provided by Arqit SKA™
