1. Overview
The Digital signatures subsystem handles operations related to applying and verifying digital signatures to ensure data integrity during cross-service interactions using specialized cryptographic modules.
2. Subsystem functions
-
Retrieving digital signature owner’s data.
-
Verifying the ownership of the applied digital signature.
-
Applying a digital signature to data entering the registry or a digital document using the registry electronic seal.
-
Verifying the ownership of the applied registry electronic seal.

A digital signature component that leverages the capabilities of an external digital signature library and provides digital signature functionality. |
5. Technological stack
The following technologies were used when designing and developing the subsystem:
6. Subsystem quality attributes
6.1. Observability
The Digital signatures subsystem supports incoming requests logging and collecting performance metrics for analysis through the web interfaces of respective Platform subsystems.

For details on the subsystem design, see: |
6.2. Portability
The Digital signatures subsystem can be migrated, deployed, and managed in the same reliable manner on different container orchestration platforms in various cloud environments or a dedicated data center infrastructure.
|
For details, see Container orchestration platform. |
6.3. Interoperability
The Digital signatures subsystem can easily be integrated with other subsystems and external systems, such as Accredited Key Certification Centers, via standard communication protocols. This ensures that the digital signatures generated by the subsystem can be verified and trusted by any recipient or third-party system, enhancing the signed documents validity and the overall reliability of the Platform.
6.4. Scalability
The Digital signatures subsystem supports both vertical and horizontal scaling.
