granularity-of-digital-certificates

We all know how painful, cumbersome and complex a process it is to obtain a digital certificate to sign your code (both binaries and source code). The Certificate Authorities have had over 20 years to create a customer-friendly process to obtain and manage certificates, but they didn’t. Most software publishers, therefore, obtain one or two certificates and sign all their products, across all geographic reasons, across all platforms (64bit, 32bit, ARM, AMD64, etc.). The result is less than a handful of certificates for dozens, if not hundreds, of digital assets, protected. We at CodeNotary call it coarse certificate signing.

What happens if you need to revoke a digital certificate? It will revoke the trust from the signed product, and all other products, platforms, regions you also signed with the same certificate. This happens because of a lack of fine granularity of asset signing.

Facebook went thru this exact scenario when they revoked their coarse granular certificate for their teenage tracking app and, as a result, all their apps for their employees also stopped working (https://techcrunch.com/2019/01/30/apple-bans-facebook-vpn/).

We at CodeNotary propose a different approach. Using our blockchain-based platform, you can sign and manage hundreds or thousands of signed assets easily on our online dashboard. Imagine giving each one of your customers their own signed binary. Imagine signing your software at the most granular level: per region, or per platform. You can then very effectively and easily revoke a signature by vertical or horizontal, or even by a customer (if the customer is not paying their dues, for instance).

In Codenotary, the issuer and the owner of a certificate are one and the same person: you. No need to go to an expensive, slow and cumbersome Certificate Authority.

Use Case - Tamper-resistant Clinical Trials

Goal:

Blockchain PoCs were unsuccessful due to complexity and lack of developers.

Still the goal of data immutability as well as client verification is a crucial. Furthermore, the system needs to be easy to use and operate (allowing backup, maintenance windows aso.).

Implementation:

immudb is running in different datacenters across the globe. All clinical trial information is stored in immudb either as transactions or the pdf documents as a whole.

Having that single source of truth with versioned, timestamped, and cryptographically verifiable records, enables a whole new way of transparency and trust.

Use Case - Finance

Goal:

Store the source data, the decision and the rule base for financial support from governments timestamped, verifiable.

A very important functionality is the ability to compare the historic decision (based on the past rulebase) with the rulebase at a different date. Fully cryptographic verifiable Time Travel queries are required to be able to achieve that comparison.

Implementation:

While the source data, rulebase and the documented decision are stored in verifiable Blobs in immudb, the transaction is stored using the relational layer of immudb.

That allows the use of immudb’s time travel capabilities to retrieve verified historic data and recalculate with the most recent rulebase.

Use Case - eCommerce and NFT marketplace

Goal:

No matter if it’s an eCommerce platform or NFT marketplace, the goals are similar:

  • High amount of transactions (potentially millions a second)
  • Ability to read and write multiple records within one transaction
  • prevent overwrite or updates on transactions
  • comply with regulations (PCI, GDPR, …)


Implementation:

immudb is typically scaled out using Hyperscaler (i. e. AWS, Google Cloud, Microsoft Azure) distributed across the Globe. Auditors are also distributed to track the verification proof over time. Additionally, the shop or marketplace applications store immudb cryptographic state information. That high level of integrity and tamper-evidence while maintaining a very high transaction speed is key for companies to chose immudb.

Use Case - IoT Sensor Data

Goal:

IoT sensor data received by devices collecting environment data needs to be stored locally in a cryptographically verifiable manner until the data is transferred to a central datacenter. The data integrity needs to be verifiable at any given point in time and while in transit.

Implementation:

immudb runs embedded on the IoT device itself and is consistently audited by external probes. The data transfer to audit is minimal and works even with minimum bandwidth and unreliable connections.

Whenever the IoT devices are connected to a high bandwidth, the data transfer happens to a data center (large immudb deployment) and the source and destination date integrity is fully verified.

Use Case - DevOps Evidence

Goal:

CI/CD and application build logs need to be stored auditable and tamper-evident.
A very high Performance is required as the system should not slow down any build process.
Scalability is key as billions of artifacts are expected within the next years.
Next to a possibility of integrity validation, data needs to be retrievable by pipeline job id or digital asset checksum.

Implementation:

As part of the CI/CD audit functionality, data is stored within immudb using the Key/Value functionality. Key is either the CI/CD job id (i. e. Jenkins or GitLab) or the checksum of the resulting build or container image.
