Digital Signature Provider in Sri Lanka​

The Central Bank of Sri Lanka requested LankaClear (Pvt.) Ltd. (LCPL) to be the financial sector Certification Service Provider (CSP). LCPL launched Sri Lanka's first Certification Authority under the brand name LankaSign in accordance with the Electronic Transaction Act, No.19 of 2006 on May-22-2009. A CSP is an authority on a network that issues and manages security credentials and public-private key pairs for message signing and encryption. As part of the Public Key Infrastructure (PKI), a CSP checks with a Registration Authority (RA) to verify information provided by the requestor of a Digital Certificate. If the RA verifies the requestor's information, the CA can then issue a Digital Certificate that can be used for the purpose of signing and encrypting electronic transactions.

LankaSign in its first phase started providing digital certificates to Banks to be used in financial transaction clearing systems, such as SLIPS and CITS (Cheque Imaging and Truncation System), where the CSP and Public Key Infrastructure (PKI) was made available on LCPL's Virtual Private Network (VPN).

Aligning with the Electronic Transaction Act, No.19 of 2006, LankaSign follows a stringent process on validating the certificate users and their respective organizations before issuing a digital certificate. Due to its high security standards, LankaSign was able to obtain certification on ISO 27001:2013 for its Information Security Management System in the year 2015.
