ETSI TS 102 690

ETSI TS 102 690 is a technical standard developed by the European Telecommunications Standards Institute for encoding and decoding digital signatures in electronic documents. It specifies how to create, verify, and manage secure, digital signatures to ensure documents are authentic and haven't been altered. This standard promotes interoperability and security in electronic transactions, especially for contexts like electronic invoicing, government communications, and digital document handling. Essentially, it provides a common set of rules for securely signing and verifying electronic documents, enhancing trust and efficiency across digital communication systems.
