Consider the following statements: A digital signature is
- an electronic record that identifies the certifying authority issuing it
- used to serve as a proof of identity of an individual to access information or server on Internet
- an electronic method of signing an electronic document and ensuring that the original content is unchanged
Which of the statements given above is/are correct?
Answer
3 only
1. Incorrect. A digital signature is not the electronic record identifying the Certifying Authority; that description fits a digital signature certificate, which is issued by the Certifying Authority.
2. Incorrect. A digital signature is mainly used to authenticate an electronic document/transaction, not as a general proof of identity to access an Internet server; that role is closer to authentication credentials or digital certificates.
3. Correct. A digital signature is an electronic method of signing a document that authenticates the signer and helps ensure the content has not been altered.
Therefore, only statement 3 is correct.
