A DAPTATION IN ( N ) CODE R EGISTRATION P ROCESS Introduction The office of Controller of Certifying Authorities (CCA) was set up under the Information Technology Act (IT Act) in the year One of the primary objectives was to promote the use of Digital Signatures for authentication in e-commerce & e-governance. Towards facilitating this, the CCA licensed eight Certifying Authorities (CAs) to issue Digital Signature Certificates (DSC) under the IT Act The standards and practices to be followed were defined in the Rules and Regulations under the Act and the Guidelines that are issued by CCA from time to time. As part of the interoperability initiative of the CCA, a comparative analysis of the certificates in use in India was carried out. Also the certificates were compared with the CCA rules and regulations for certificate formats. The comparative analysis of the certificates has highlighted that the majority of the interoperability problems in certificates are due to inconsistency in the Issuer and Subject fields of the certificates. Additionally, many fields were interpreted differently by the CAs. Some key observations from the comparative analysis revealed: 1. The Issuer field in the digital certificates has been interpreted and /or used in 20 different ways especially its sub-fields. The variations ranged from name of the application for which the certificate is meant to company / organization names operating applications. 2. The Subject field shows variety of usage for its sub fields. We observed non-standard implementation of the organization parameters. The Organization Unit sub field interpretation varies across the Certifying Authorities and contains information such as certificate class, subject designations, application specific information etc. 3. There is variation in usage and interpretation of almost all fields in the certificate including fields such as Certificate Policy, Authority Key Identifier, Key Usage, CRL distribution points etc. (n)code Solutions CA s Public Certification Services Call Toll Free Page 1 of 7
