Tamper-evident record history
Each version of a record is hashed and the hashes are chained or anchored in an append-only log, so any later change to history is detectable by anyone holding an earlier hash.
GCRI · Registry
Cybersecurity and cryptography protect a registry’s integrity: that records are not altered without trace, that only authorised people change them, and that what a reader receives is what the issuer published. In registries the main threat is often quiet tampering rather than outage, so integrity and audit matter as much as availability.
Cybersecurity and cryptography protect information システム and data from unauthorised access, disruption and manipulation. They address threats that can spread rapidly across interconnected digital and physical systems. In governance and institutions and research and evidence, cybersecurity analysis identifies how a single compromise can propagate across sectors that share software, vendors or networks. It informs resilience requirements and cyber insurance. The canonical description is on STEM Commons.
Each version of a record is hashed and the hashes are chained or anchored in an append-only log, so any later change to history is detectable by anyone holding an earlier hash.
Exports and data releases are signed with keys whose public halves are published, so consumers can verify origin and integrity before ingesting, and a compromised mirror cannot pass off altered content.
Every route by which a record can change, from the interface and bulk import to administrator tools and pipelines, is modelled for abuse, including insiders and stolen credentials, and each route is logged.

The model runs on the teaching values set by the controls. To calibrate it for a place, read it against these admitted layers and series, which this page’s map can draw:
6 本の柱を通じて、Nexus Consortium が主導
Controls are tested through red-team exercises, audits and formal analysis of cryptographic schemes. Incident data are used to check whether defences performed as intended.
| 確認 | 実施方法 |
|---|---|
| Hash verification | Published records and exports are re-hashed on a schedule and compared with the logged values |
| Access review | Accounts with edit and administrator rights are reviewed against current roles, and stale access is removed |
| Penetration testing | Edit paths and interfaces are tested by an independent team against the threat model |
| Restore drills | Backups are restored to a clean environment and compared with the live registry |
Adversaries adapt, so historical data may not reflect future attacks. Software supply chains and legacy systems introduce weaknesses that are hard to inventory.
