Krown and ExeQuantum Announce Joint Patent for SiFA, a Breakthrough Cryptographic Authentication Layer Designed to Stop Email and Payments Fraud Before It Happens

Where traditional MFA relies on human action (codes, approvals, prompts), SiFA moves identity verification fully into the cryptographic layer.It binds identity + device + intent and validates them programmatically in milliseconds. If the signature does not match the correct cryptographic context, the action simply does not proceed or gets flagged.
Initially delivered as a lightweight Outlook add-in, SiFA requires minimal user training, no new behavior beyond additional integration, and no tech no-how, making it immediately deployable across enterprise environments.

Payments fraud, invoice redirection, procurement tampering, and supply-chain impersonation attacks all share one pattern: a trusted identity is hijacked at the moment of instruction. SiFA shifts trust away from human perception and into cryptographic certainty.
If the signature isn’t cryptographically valid, the instruction gets blocked or flagged.This is a fundamental change in how organisations can defend themselves against AI-enabled malicious actors.

“SiFA allows us to move trust decisions out of the human inbox and into cryptographic reality. By partnering with ExeQuantum, we are reinforcing Krown’s position as an innovator in creating the quantum secured future and at the same time giving businesses a practical way to stop payments fraud before it happens.”

He added:
“We are already piloting SiFA with one of Australia’s largest construction companies after a significant payments fraud incident. Critical approvals still flow over email. SiFA is a simple way to make those flows safer without slowing the business down.”

"SiFA represents a step-change in how organisations protect identity and intent in high-risk workflows. We engineered SiFA to replace vulnerable human checks with cryptographic certainty in milliseconds. Through our partnership with Krown, we’re bringing this breakthrough into sectors where losses are accelerating fastest — starting with payments and procurement workflows that remain dangerously exposed today.”
He continued:
“This is the beginning of a new authentication category, not an incremental feature. SiFA is built on ExeQuantum’s quantum-safe architecture and forms the foundation of a long-term innovation stream to secure critical workflows across construction, supply chain, healthcare, blockchain and financial services.”

Following its initial deployment, SiFA will expand to secure workflows across procurement, logistics, vendor onboarding, approvals, and blockchain-based transactions — any workflow where identity and authority intersect with value transfer. Krown and ExeQuantum are already in discussions with industry leaders in construction, healthcare, supply chain, and BFSI as part of the first wave of sector rollouts.

This is not a reseller arrangement. The SiFA patent is a jointly originated technology, co-developed by ExeQuantum’s cryptographers and Krown’s identity and workflow engineering teams. It represents the first step in a multi-year innovation partnership designed to bring quantum-safe identity assurance into everyday enterprise workflows. Following its initial deployment, SiFA will expand to secure workflows across procurement, logistics, vendor onboarding, approvals, and blockchain-based transactions — any workflow where identity and authority intersect with value transfer. Krown and ExeQuantum are already in discussions with industry leaders in construction, healthcare, supply chain, and BFSI as part of the first wave of sector rollouts.

This announcement marks:
• One of Australia’s first co-developed quantum-safe authentication patents
• A direct response to the surge in AI-enabled business fraud
• A security innovation already validated by a major ASX-listed enterprise
• A practical pathway to securing the workflows that account for billions in annual fraudlosses globally
• A new authentication category poised for rapid adoption across high-risk industries

The first SiFA release, an Outlook-based cryptographic identity layer, will be available to enterprise customers in early to mid 2026, with private preview programs open now for eligible organisations.

Krown is already a leader in the Blockchain & DeFi industries, as well as pioneering the
Quantum Secured Blockchain space. Now, along with ExeQuantum, Krown will lead inidentity-driven workflow security, enabling organisations to execute approvals, payments,
and business-critical actions with confidence. By blending secure identity, elegant workflow
design, and enterprise-grade deployment models, Krown helps companies reduce fraud risk
while maintaining operational speed.
