Hongkong Post's new root certificateadmitted to Microsoft Root Certificate Program

Hongkong Post's new root certificate ("Hongkong Post Root CA 1") was admitted to the Microsoft Root Certificate Program

Starting from April 2004, Hongkong Post's new root certificate ("Hongkong Post Root CA 1") was admitted to the Microsoft Root Certificate Program, in addition to the old root certificate ("Hongkong Post Root CA") which had already been admitted in July 2003. The program aims at protecting Microsoft customers from security issues related to the use of public key infrastructure (PKI) certificates. This means that Internet Explorer and Outlook Express users of Windows XP and Windows 2003 will now trust certificates issued by Hongkong Post under the two root certificates.

Users on platforms before Windows XP can also pick up and install the two Hongkong Post root certificates to their operating systems when they perform the Windows Update at URL, http://windowsupdate.microsoft.com. Please note that Root Certificate Update is not a critical update and users need to explicitly click-open the optional Windows 98/ME/NT/2000 Update list to include the Root Certificate Update.

The admission of Hongkong Post to the Microsoft Root Certificate Program is a solid proof of the trustworthiness of the Hongkong Post CA System and e-Cert.

The conditions on using a digital certificate will deal with the liability of the certificate owner and the CA. The following is taken from the Certificate Practice Statement (CPS) of CA of the University of Science and Technology and are quoted here as an example:

Liability of Certificate Owner

Without limiting other certificate owner obligations stated in the CPS, certificate owners are liable for any mis-representation they make in certificates to third parties that, reasonably rely on the representations contained therein.

Liability of HKUST CA


· Does not warrant the accuracy, authenticity, completeness or fitness of any unverified information contained in certificates or otherwise compiled, published, or disseminated by or on behalf of HKUST CA.

· Shall not incur liability for representations of information contained in a certificate, provided the certificate content substantially complies with the CPS.

· Does not warrant "non-repudiation" of any certificate or message (because non-repudiation is determined exclusively by law and the applicable dispute resolution mechanism).

Certificate Repository

Certificate Internal Database is a database to keep track of the pending certificate request, issued or revoked certificate, private Certificate Revocation List (CRL), etc. Only RA and CA have the rights to update this database. A web user interface will be provided for users to query the status of their certificate requests and any issued or revoked certificate. Various fields in certificate, such as serial no, expiry date, subject name, etc will be indexed. This will allow faster queries based on these standard attributes.

A high performance directory server, based on the IETF LDAP standard, is used as a public repository of Certificate Revocation List (CRL), user and CA certificates. Its design is based on the RFC 2587 schema. A standard LDAP interface will be provided to native client for retrieving certificate for applications like S/MIME or SSL client authentication.

HKU Certification Authority (HKUCA)

HKU Certification Authority (HKUCA), run by the HKU Computer Centre, set up public key infrastructure (PKI) to issue HKU digital certificates (HKU-Cert) from 22nd September 2000 to current HKU staff and students (HKU members).

Personal: the HKU-Cert of a HKU member serves as his digital identity for him to authenticate himself and sign electronically in using HKU Electronic Services Delivery (HKUESD) of digital signature applications.

Server: from 1st February 2002, HKUCA also issues HKU-Cert (Server) to administrators of computer servers approved by HKUCA. The server named in a HKU-Cert (Server) can use the certificate in applications employing Secure Socket Layer (SSL) encryption.

According to the University, HKUCA is not seeking Recognized CA status, as defined in the Electronic Transactions Ordinance, from the Director of Information Technology Services Department of the HK SAR Government. Therefore, HKUCA is not subject to the governing rules and regulations set out in the Electronic Transactions Ordinance.

New Offences under ETO

To safeguard the integrity and trustworthiness of the CA system, three new offences were created by the Electronic Transactions Ordinance, even of which can result in fine or imprisonment if offended.

A person who makes a false claim that a person is a recognized certification authority commits an offence and is liable in the case of an individual to a fine at level 6 and to imprisonment for 6 months and in any other case, to a fine at level 6.

Digi-Sign Certification Services Limited (Digi-Sign)

Digi-Sign is the first private CA recognised pursuant to the Electronic Transactions Ordinance. Its recognition status was granted by the Director of Information Technology Services in July 2001 on application by Digi-Sign.

Digi-Sign was only set up in October 2000. Its services as a certification authority was prior to its recognition operated by Tradelink (full name being Tradlink Electronic Commerce Limited). Digi-Sign is therefore a spin-off and wholly-owned subsidiary of Tradelink. At the time of the recognition, Digi-Sign issues two classes of recognised digital certificate.The two classes of recognised certificates are called ID-Cert. They are issued by Digi-Sign under the Certification Practice Statement (CPS) issued by Digi-Sign.
