Hi, Dear, PKI experts,
 
I understood that the non-repudiation could achieved with not only technology but also policy/law.
 
In Korea, we have Digital Signature Act, accredited CAs, and 16million accredited certificates.
By this law, when a user wants to transfer the money by Internet, the banks always request the user to generate a signature (PKI) for non-repudiation.
By keeping this signature, the banks convinced that user could not repudiate the transaction he/she made, later.
Are there any sillimar cases for preserving non-repudiation in any contries?
 
BTW, The ISO/IEC 13888-2 provides the non-repudiation services by the symmetric-key basis, not by PKI.
Are there any commercial or public ‘Non-Repudiation Services’ for symmetric-key basis? 
(perhaps Chip Authentication Program by EMV ?)
 
If any, kindly notify me the basis of the technologies and related policy.
 
Thanks.
Shim, Hee-won.
