KSIGN's PKI products issue digital certificate to authenticate people's identity on the world of digital communication with using electronically embodied digital signature algorithm with PKI cryptography.
KSIGN's security products are enabled with complying fundamentals of PKI technology that are developed to carry out such functions to issue digital certificate, register user, time stamp, real-time certificate verification, key escrow, etc on via wireline/wireless digital communication environment.
In addition, KSIGN enables safe and trusted Internet banking, online stock trading, online payment and other security sensitive digital communication by providing strong user authentication.

'KSignPKI (Public Key Infrastructure) is a critical security foundation that provides trusted user authentication service to enable safe data transaction on the Internet through confirming identity between sender and receiver 'KSignPKI' constructs X.509v3 based certificate administration system.

'KSignPKI PRO (Professional)' is a critical security foundation that provides trusted user authentication service on Windows NT/2000/2003.
'KSignPKI PRO' can be also integrated into Unix, Linux and other operation system environments as well as supporting convenience GUI(Graphic User Interface) function to facilitate easy of use.

'KSignWPKI(Wireless PKI)' provides perfect security infrastructure on fast changing wireless communication environment by enabling CA service through mobile phones, PDAs and other handheld devices.With complying wireless communication standard protocols such as WAP and MME, 'KSignWPKI' provides safe and fast CA service over the wireless communication devices in spite of their limited technical capabilities.

'KSignKMI(Key Management Infrastructure)' is the product to manage crypto keys that contains confidential document and personal information at PKI-based system.'KSignKMI' carries out key escrow to prevent from losing or reproducing secrete key for encryption, prevent from unauthorized exposure of enterprise/organization's digital asset, and prevent from losing keys on purpose by administrator.

'KSignTSA (Time Stamp Authority)' will record the present time data on specific information to approve such existence of the corresponding information at selected time.'KSignTSA' issues tokens to approve the point of time, provides signature and security related libraries, handles requests to approve the point of time and manages data for issued timestamp tokens.

'KSignOCSP(Online Certificate Status Protocol)' retains validity of certificate in real-time basis. Therefore, users can request to verify their certificates and the system sends the result of certificate status to users via online in real-time basis.'KSignOCSP' can be either constructed with CA or constructed independently to perform OCSP function of own, and it enables consistent management of security policies such as real-time certificate verification function.
