Kerala Water Authority Online Tenders / KWA eProcurement



A digital signature, which is an electronic signature, can be used to protect information being shared via the internet. By using an electronic signature, e-mail messages and electronic documents can be encrypted.

Like all digital signature certificates, once the sify DSC expires, it is listed in the certificate revocation list (CRL). Organisations to which digitally-signed documents are submitted, can check the validity period of a certificate from the CRL. Certificates listed in the CRL should are no longer valid. Along with validity, a CRL also mentions the reason why the digital certificate was revoked.

Kerala Water Authority (KWA) has introduced a secure e-tendering and e-procurement system. KWA e-tendering portal is a secure web-based platform where all tender-related activities can be carried out electronically. The conventional paper-based tendering process has been replaced with the electronic tendering process to increase transparency in purchases.

Sify class 3 digital certificates are ideal for participating in the online tendering process. New contractors can view and download tenders invited by KWA on the e-procurement portal. With sify class 3 DSC, vendors can be assured that their data on digitally-signed documents cannot be hacked on the internet. The information provided by vendors is totally secure. The data shared by registered contractors is used only by the respective departments for evaluation and awarding of tenders.

2.    Enabling the Active X controls in the Internet Explorer browser
3.    Installing the root and chain certificates of the
