Anders, As you said, we may not get sufficient informations to standardize digital signature. But, in case of Korea, I'll sufficiently give them. The spec. and interface are almost standardized by governmental rules to all vendors. In Korea, the own cryptic algorithm has been encouraged, so vendors couldn't use browser-implemented things such as DES. This is first reason to use activex controls. Second is for digital signature. Legally, all data must be signed by user's key. When the money is sent, it needs to know who sends the money. So activex control has almost same user interface with browser's certificate manager. When an user enters an internet banking site, activex are embedded. User's data by action go to activex control and are encrypted by SEED and signed by user's key. Encrypted and signed data gives hidden form in web page again. When an user submit it, the data were transferred to web server. The server-side application decrypts and verifies the data and proceeds proper actions. Web server transfers the web page by requested actions. First thing is not standardized. National algorithm such as SEED or Camella is problems between browser vendor and its governments. Second can be done such as (re)issue and revocation of personal certificates, the digital signature such as old crypto.sign.Text(). As following is one of this efforts. http://middleware.internet2.edu/pki06/proceedings/rundgren-websigning.ppt Channy On 10/31/06, Anders Rundgren <anders.rundgren at telia.com> wrote: > >> >The use of proprietary mechanisms (mostly ActiveX controls) for > >> >digital signatures is common in Korean sites as well, including > >> >Korean government sites. > > >> That's right.
