Cybernetica to deliver next-generation file encryption standard for Estonia
Cybernetica has successfully completed additional technical delivery of the CDOC2 project for the Estonian Information System Authority (RIA), implementing a comprehensive upgrade to Estonia’s national file encryption standard that addresses critical security requirements and enables long-term secure document storage.
CDOC – Crypto DigiDoc – is the file format used to store encrypted DigiDoc files. The objective of the CDOC2 project was to replace the previous CDOC 1.0 standard. It became clear during the 2017 ROCA cryptographic vulnerability crisis that additional protections are necessary. Updates to the standard are two-fold:
- modernising the encrypted file format and adding additional encryption algorithm support
- providing additional protection against harvest-now-decrypt-later attack and preparing CDOC system for quantum computer threat
