Applications / execution and key integrity
Cryptographic guarantees about what executed.
Integrity is the substrate underneath every other journey. Without verifiable execution and key integrity, every signal sits on a probabilistic foundation. Execution evidence makes integrity a first-class observable.
“I need verifiable proof that the device-side execution is what the spec describes. I need to see when keys rotate. I need to know which tokens were rejected and why.”
Three operator outcomes from one signed substrate.
- ·01 Attribute every key rotation to its device — reinstall abuse becomes diagnosable
- ·02 Classify verification failures by specific rejection reason
- ·03 Travel cryptographic guarantees with every signed event — audits become forensic-grade
Integrity claims today rest on point-in-time attestation snapshots and behavioural inference. Between checkpoints, integrity is assumed. Audits depend on assumption.
The operational shifts this journey enables.
Each item below is something your operations, fraud, support, or audit team can do that they cannot do today. Read in executive language; the technical contract behind each is referenced compactly at the foot of this section.
- ·01 Reinstalls and rotations are attributable
Attribute every key rotation to its device
today
App reinstalls and rotations are observable only in aggregate. A device that rotates to evade detection blends in.
with execution evidence
Every rotation is captured per device. Repeated rotation flags as a reinstall-abuse candidate, in real time.
- ·02 Rejections become diagnosable, not anonymous
Classify rejections by specific reason
today
Failed verifications come back as anonymous counts. Diagnosing them takes weeks of audit work.
with execution evidence
Each rejection arrives with the precise step that failed. Audits move from anonymous counts to forensic-grade traceability.

YinkoShield supplies the signed evidence and the rejection reasons. You apply your own policy: investigate, escalate, or feed into the audit substrate.
Run these signals on your own dashboard.
Signal Lab ships a hosted dashboard, scripted scenarios, and a CSV bulk replay. Every signal in this journey has a reproducible scenario you can run, watch, and reset. No installation on your infrastructure.
