Q94 (IAS/2019) Science & Technology β€Ί ICT, AI, Cybersecurity & Emerging Tech β€Ί Digital identity and authentication Official Key

Consider the following statements : A digital signature is 1. an electronic record that identifies the certifying authority issuing it 2. used to serve as a proof of identity of an individual to access information or server on Internet 3. 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?

Result
Your answer: β€”  Β·  Correct: C
Explanation

The correct answer is option C (Statement 3 only).

A digital signature is an electronic method of signing an electronic document[1], and authenticated digital signatures provide cryptographic proof that a stated entity signed a document and that the document hasn't been altered[2]. This confirms that statement 3 is correct.

Statement 1 is incorrect because it confuses a digital signature with a Digital Signature Certificate (DSC). A digital signature is an electronic method of signing an electronic document whereas a Digital Signature Certificate is a computer based record[3], and it is the certificate, not the signature itself, that Certifying Authorities (CAs) issue for electronic authentication of users in cyber world[4].

Statement 2 is also incorrect as it describes the function of digital certificates or authentication credentials used for identity verification and access control, rather than the primary purpose of a digital signature, which is to sign documents and ensure their integrity. Therefore, only statement 3 accurately describes what a digital signature is.

β€œIf the value of goods transported is more than worth Rs. 50,000/- then generation of e-way bill is mandatory. E-Way Bill is basically a compliance mechanism wherein by way of a digital interface the person causing the movement of goods uploads the relevant information prior to the commencement of movement of goods and generates e-way bill on the GST portal. E-way bill is a mechanism to ensure that goods being transported comply with the GST Law and is an effective tool to track movement of goods and check tax evasion. The E-Way bill under the GST regime replaces the Way bill (which was a physical document) which was required under the VAT regime for the movement of goods.β€’ Composition levy is an alternative method of levy of tax designed for small businesses whose turnover is up to Rs.”
Why relevant

Explains the e-way bill as a digital interface replacing a physical document to ensure compliance and to track movement β€” an example of digitized documents serving legal/official functions.

How to extend

One can extend this to ask whether digital records used for legal compliance (like e-way bills) require mechanisms (e.g., signatures) to guarantee authenticity and unaltered content.

In simple words, it is the electronic digital world for communicating or accessing information over computer networks without physical movement of the sender and the receiver... It is also referred to as the Internet. Cyberspace exists everywhere. It may be in an office, sailing boat, flying plane and virtually anywhere. The speed at which this electronic network has spread is unprecedented in human history. There were less than 50 million Internet users in 1995, about 400 million in 2000, over two billion in 2010 and about 5.4 billion in 2023.”
Why relevant

Defines cyberspace as the electronic computerized world for communicating and accessing information β€” establishing the domain where electronic signing and verification would operate.

How to extend

A student could use this to frame the question: within cyberspace, what technical methods (e.g., digital signatures) are used to guarantee authenticity and integrity of electronic documents?

Pattern takeaway: UPSC Tech questions often test the 'Mechanism' rather than the 'Application'. Knowing 'it is used for online login' (Application) is less safe than knowing 'it is a hash encrypted by a private key' (Mechanism).

πŸŒ‘ The Hidden Trap

The 'Root Certifying Authority of India' (RCAI) is operated by the CCA (Controller of Certifying Authorities). While CAs issue certificates to public, the CCA regulates the CAs. This hierarchy is a potential future statement.

⚑ Elimination Cheat Code

Apply the 'Noun vs. Verb' test. Statement 1 calls a signature an 'electronic record'. A signature is an 'act' or 'method' (Statement 3) applied TO a record. The 'record' that identifies the issuer is an ID card (Certificate). This category mismatch eliminates Statement 1.

πŸ”— Mains Connection

Mains GS-2 (e-Governance): Digital Signatures provide 'Non-repudiation'. This is the legal backbone of initiatives like e-Office and GeM (Government e-Marketplace), ensuring officials cannot deny approving a file later.
