• Potentially of interest because: relevance of these technology building blocks in digital public infrastructure
• Keywords: identity, credential, verification, digital public infrastructure

Digital credentials based on IETF standards (and standards in other SDOs) have use cases ranging from individual credentials, such as driver’s licenses, age-verification, and vaccination proofs, to business-to-business or business-to-government application. One example is fraud and counterfeiting prevention in cross-border trade documents by protecting digital representations of mill test reports, bills of materials, bills of lading, or commercial invoices. In order to meet privacy, security, and sustainability objectives, digital credentials need to be designed with awareness of computation and storage constraints associated with their use cases.

SPICE aims to document digital credential formats based on existing IETF standards, and extend them to support stakeholders that are building compliance and automation systems based on industry adopted cryptography and protocols. These building blocks are likely to show up in digital public infrastructure.
