ID Card as SSCD

• The private key never leaves the card
• The key material cannot be extracted from the card
PIN code Security

• Instead, we supply 5-digit transport PIN in secured envelope
• Signature PIN can activated ONLY ONCE
• Signature PIN change is possible. Reset is NOT

Access conditions
• FREE for all eID holders, with limited space and document

Signatures for Legal Entities
Current Status
• The project is ongoing
• One of the TOP PRIORITIES of Year 2013 for PSDA
Possible fields of application
• Signing contracts on behalf of organization
• Notary services to eliminate paper documents as much as
• Issuing electronically signed birth certificates, property
ownership etc.
• Electronic Apostille
Challenges for Legal Entity Signatures
Who is signing?
• Signature seems to be always performed by some natural person and
then sealed
• Do we really need to identify signer on the birth certificate?
• This is generated from the electronic system anyway!
• Workflow actions must be securely logged in the system. And
possibly go to Archive then
By whom the key is controlled?
• Sometimes, it’s a person (CEO of the company, etc)
• Sometimes the key is under control of the organization’s electronic
Possible solution: Attribute Certificates
• We don’t need to establish additional issuing facilities and
manage additional secure tokens
• Attribute certificate can be issued online to eID user
• National Agency of Public Registry, Notary chamber, etc. can
act as attribute authorities
• Attribute authorities must have required software in place
• Content of AC must be standardized
• Short-lived AC or OCSP calls?
And how about birth certificates, etc.?
Possible solutions
• We can mandate using HSM for secure key storage
• There will be a special, standard procedure of issuing and
enrolling certificate in HSM
• Thus we may say we have an SSCD and the signature is qualified
Open Questions
• Do we really need such a complexity?
• Especially, if we may need e-Apostille for such documents?
• Do we need to establish sector-based CA’s? (For banks,
insurance, government, etc.)
E-Signature and E-Document Law
Adopted in 2008
• Mainly based on European Directive 1999/93/EC
Changes are Planned
• We are establishing an inter-agency working group to propose
new changes in law
Technical regulations
• Regulations about certificate authority accreditation are in place
• Other regulations may be introduced
Signature and Document Formats
Document Format
• The current law considers only textual information as an
electronic document
• We use PDF (based on ISO/IEC 32000-1) format
Signature Format
• Signatures of *AdES family of ETSI standards were found to be
permitted under the Georgian signature law
• PAdES (ETSI TS 102 778) signatures are used
• PAdES-LTV is highly recommended as citizen’s certificates
expire in 2.5 years
Next Plans for Signatures
Make E-Signatures usable in everyday life
By further simplification of eID usage, other signature schemas, etc.
Promote digitally-born documents
Do all graduates need paper-based university diploma?
Minimize scanned documents and save time
If your diploma is electronic, there is no need to look for a scanner to upload it in online job
application system
eID Login Applet

• Uses Attribute Exchange 1.0 to deliver person’s
information to Relying Party
Additional Features
• Easy to integrate
• Well-documented
• Avoids problems with broken Java installation
Citizen’s consent on attribute exchange
Integration with Civil Registry WS
What is Civil Registry WS?
• SOAP web service which gives personal data
• Right now sharing with 3rd parties is possible only after
written consent of the data subject
• It’s a commercial service
Integration Possibilities
• Implement web-based consent using digital signature
• Thus, it’s possible to cover additional segment of clients

Key Project: Seafarer’s Identity
What is SID?
• Seafarers identity document is a special document under regulations of
International Labor Organization
• It’s mainly based on ICAO 9303 with some important modifications
• Apart from SID, seafarers must also have documents which prove their
qualification and competency
• We implement this project In cooperation with Maritime Transport Agency of
• Full cycle of document issuing: from application collection to printing and
