Role of Certifying Authorities (CAs) under the IT Act, 2000
What are Certifying Authorities?
Certifying Authorities (CAs) are entities licensed by the Controller of Certifying Authorities (CCA) under the IT Act, 2000. Their primary role is to issue digital certificates which facilitate the use of digital signatures — the electronic equivalent of handwritten signatures — to authenticate identity and secure electronic transactions.
Functions and Responsibilities of Certifying Authorities
Issuance of Digital Certificates (Section 24)
CAs issue Digital Signature Certificates (DSCs) that verify the identity of individuals, organizations, or devices in electronic communication.
The certificate contains the public key of the subscriber, identity details, validity period, and the CA’s digital signature.
Verification of Subscriber Identity (Section 24)
Before issuing a certificate, CAs verify the identity of the applicant based on documentary evidence or other means.
This is critical to prevent identity fraud and ensure trust in electronic transactions.
Maintaining Certificate Repositories (Section 29)
CAs maintain publicly accessible repositories of issued certificates and their status (valid, suspended, revoked).
This enables parties to verify the validity of digital certificates at any time.
Suspension and Revocation of Certificates (Section 28)
CAs can suspend or revoke certificates in cases such as compromise of private keys, false information, or cessation of business.
They must notify the Controller and update the repository accordingly.
Compliance with IT Act and Regulations
CAs must comply with conditions set by the Controller, including security standards, audit requirements, and operational procedures.
They are subject to supervision and periodic inspections.
Secure Key Management
Ensure secure generation, storage, and management of cryptographic keys associated with digital certificates.
Prevent unauthorized access to private keys.
Record-Keeping and Audit
Maintain records of all issued certificates and transactions for a prescribed period.
Submit to audits as required by the Controller.
Importance of Certifying Authorities
Provide the trust infrastructure necessary for secure electronic commerce and governance.
Enable authentication, non-repudiation, and integrity in digital communications.
Facilitate compliance with legal requirements for electronic contracts, filings, and records.
