Kaveri Pharma's finance team signs its electronically filed returns using a digital signature certificate. Which statement correctly describes the technology and legal position under the IT Act, 2000?

A digital signature uses an asymmetric key pair: the signer's private key creates it and the corresponding public key verifies it. This differs from symmetric shared-key encryption and from a scanned handwritten signature, which is not a digital signature under the IT Act.

  1. AA digital signature uses an asymmetric key pair, with the signer's private key creating the signature and the public key verifying itCorrect
  2. BA digital signature uses one shared secret key known to both sender and receiver for signing and verifying
  3. CA digital signature is merely a scanned image of the handwritten signature and has legal validity only when notarised
  4. DThe public key is used to create the signature and the private key to verify it

Explanation

The IT Act authenticates electronic records through digital signatures based on an asymmetric crypto system and hash function. The signer creates the signature with the private key and anyone verifies it with the public key. A shared secret key is symmetric encryption, and a scanned image is not a digital signature.
