Step 1: Understanding the Concept:
Under the Information Technology Act, 2000, a Certifying Authority (CA) is a trusted entity licensed by the Controller of Certifying Authorities (CCA) to issue, suspend, and revoke Digital Signature Certificates. These certificates are used to create digital signatures.
Step 2: Detailed Explanation:
Let's examine the options:
- M/s. Safescrypt: Safescrypt is a licensed Certifying Authority in India. It is one of the recognized CAs that provide digital signature certificates to the public.
- M/s. NCERT (National Council of Educational Research and Training): NCERT is an autonomous organisation of the Government of India that advises the Central and State Governments on policies and programmes for qualitative improvement in school education. It is not a public Certifying Authority for digital signatures.
- M/s. MTL: This likely refers to MTNL (Mahanagar Telephone Nigam Limited). While MTNL did have a CA service called 'Trustline', it is not as universally recognized as other CAs and its services have varied. However, NCERT is definitely not a CA.
Since NCERT is not a Certifying Authority, the option "(D) All the above" is incorrect. The only clear and correct option among the choices is M/s. Safescrypt. Other prominent CAs in India include eMudhra, (n)Code Solutions, and the National Informatics Centre (NIC).
