Understanding Class 2 Digital Signatures

What is a Class 2 Digital Signature?

A Class 2 Digital Signature is a form of electronic authentication that ensures the integrity of digital documents and verifies the identity of the signatory. It is issued by a Certifying Authority (CA) after a stringent validation process, thereby assuring the recipient that the document has not been altered and was signed by the identified individual or entity.

How Does a Class 2 Digital Signature Work?

The process of obtaining and using a Class 2 Digital Signature involves several key steps:

Application Submission: 

The signatory submits their application along with the necessary documents (such as proof of identity and address) to a Certifying Authority (CA) approved by the government.

Verification Process: 

The CA performs a thorough verification of the submitted documents to validate the identity of the applicant.more This may include cross-checking against government databases or physical verification.

Digital Signature Issuance: 

Upon successful verification, the CA issues the Class 2 Digital Signature in the form of a digital certificate stored on a secure USB token or a smart card.

Signing Documents: 

To sign a document digitally using Class 2 Digital Signature, the signatory plugs in the USB token or smart card, accesses the document, and applies the digital signature using specialized software. The signature encrypts the document, ensuring its integrity and authenticity.

Verification by Recipient: 

The recipient of the digitally signed document verifies the signature’s authenticity using the CA’s public key to decrypt and validate the signature. This confirms the document’s integrity and the signer’s identity.
