Ningbo CA, the Certificate Authority for the city of Ningbo in China, has partnered with Guardtime to provide electronic data authentication using Guardtime's Keyless Signature Infrastructure (KSI) technology for Ningbo government services. KSI allows Ningbo CA to provide functions and values where traditional public key infrastructure is limited, such as intrinsic time binding for data and independence from cryptographic keys. Ningbo CA and Guardtime will collaborate to use KSI to digitally sign and timestamp data for electronic receipts and tax services alongside existing PKI solutions.

1. China’s Ningbo Certificate Authority Selects KSI for Government Services
Ningbo CA, has teamed with Guardtime to provide electronic data authentication for
Ningbo government services.
Ningbo (China) | Palo Alto, CA (USA) - April 08, 2013 -- Ningbo CA, the Certificate Authority for
the city of Ningbo in Zhejiang province in the People’s Republic of China, has teamed with
Guardtime ( http://www.guardtime.com ), the leading provider of Keyless Signature Infrastructure
(KSI), to provide electronic data authentication for Ningbo government services.
Chaozong Chen, General Manager of Ningbo CA, said, “KSI’s unique features such as
independency of verification, intrinsic time binding for data, universal accessibility cross platforms
and lack of keys allow us to provide functions and values where traditional public key
infrastructure (PKI) is limited. The future proof from quantum computing is of course a major
benefit.”
“While our PKI based solutions have been widely adopted, we see a growing need to prove data
integrity and time on a massive scale, with cases where customer identification registration is
unpractical and less important, such as electronic receipts for cash based transactions,” said
Chaozong Chen.“These are where KSI can help. It is strategically important for us to start
integrating KSI with our successful PKI solutions and this will help us maintain our leadership in
the field.”
Ningbo CA and Guardtime ( http://www.guardtime.com ) are collaborating to use KSI to digitally
sign and timestamp data for electronic receipts and tax related government services together with
existing PKI based solutions. Ningbo CA will be a local KSI distributor and service center for the
Zhejiang province and its 55 million inhabitants.
“We are thrilled to announce the first Chinese Certificate Authority to select KSI for data
authentication and look forward to working closely with Ningbo CA to drive new innovative
solutions,” said Jian Tan, Guardtime China General Manager.
Guardtime Chief Scientist AhtoBuldas added, “Recent announcements by Quantum Computing
pioneers DWave confirm that it is only a matter of time before practical quantum computing
becomes a reality and we strongly recommend that all Certificate Authorities consider KSI as a
complementary service offering to existing PKI services. The verification does not rely on the
security of cryptographic keys and can be derived using formal verification methods
independently from the service provider. Security professionals can sleep easier at night and be
prepared for a post-quantum cryptography world.”
Most recently, Guardtime announced a partnership with the Philippines government to validate
physical document integrity, with CAT Telecom, the state-owned telecommunications incumbent
in Thailand, and with China Telecom, the largest fixed line telecommunications service provider in
the People’s Republic of China, establishing China Telecom as a Keyless Signature service
provider via its Tianyi 3G platform.

2. About Guardtime:
Guardtime was founded with the goal of solving one of the biggest problems in computing: how to
authenticate electronic data. Guardtime's Keyless Signatures provide proof of signing time,
signing entity and data integrity while the verification of the signature can be done offline without
reliance on keys, secrets, or the existence of a trusted third party. Guardtime's mission is to
change the world to one in which Keyless Signatures are ubiquitous and a natural part of the
everyday data lifecycle, whether on disk, in transit, or in the Cloud.
