Functions
and Legal Effects of a licensed Certification Authority
A Certificate Authority provides such services as the confirmation
of the identity of the transacting parties during electronic transactions(Authentication),
checks for data alteration and manipulation(Integrity), and prevention
of repudiation for occurrence of e-commerce activities(Non-repudiation).
In addition, certification provides data confidentiality and access
control.
The legal effect of a digital signature is conveyed only when it
is based on the digital certificates issued by a licensed Certification
Authority. Therefore, certificates from CAs without government authorization
cannot be protected by law.
According to Clause 7 of the Electronic Transaction Consumer Protection
Policy, online shopping malls must receive a certificate from a Certification
Authority and display it for their consumers.
