Description
BDOC is a digital signature format specific to Estonia. National BDOC 2.1 standard EVS 821:2014 http://www.evs.ee/products/evs-821-2014. The format comprises two technically different subformats. In order for end users to be able to easy differentiate between these subformats, each subformat has obtained its own file extension - .bdoc and .asice. .bdoc or BDOC-TM or ASiC-E LT-TM is the BDOC signature format with a time-mark. The RFC 2560 standard based time-marks ensure long-term proofability of the authenticity of the signature. This format has been used as a default digital signature format in Estonia since 2015. .asice or BDOC-TS or ASiC-E LT is the BDOC signature format with a time-stamp. In contrast to the LT-TM format, long-term proofability of the authenticity of the signature is ensured by the RFC 3161 standard based time-stamps. The ASiC-E LT signature is highly compliant with the international standards. One can also differentiate between the subformats by inspecting the signature0.xml file: BDOC has element "SignaturePolicyIdentifier" whereas ASICE includes element "SignatureTimeStamp".
