Digital signature

Digital Signature in Jharkhand- A digital signature is exactly what it sounds like a modern alternative to signing documents with paper and pen. It uses an advanced mathematical technique to check the authenticity and integrity of digital messages and documents. A digital signature is a PKI-based digital certificate that authenticates the identity of the signer and ensures electronically transmitted documents and digital messages have not been forged or tampered with. Digital signatures are similar to physical signatures in the sense that both are unique to the signer, except that in the case of digitally signed documents, a digital signature offers far more security and the assurance of the document’s origin, identity, and integrity. Based on the highest standard of security, digital signatures are legally binding in the United States and many other countries. It guarantees that the contents of a message are not altered in transit and helps us overcome the problem of impersonation and tampering in digital communications. Digital signatures also provide additional information such as the origin of the message, status, and consent by the signer.

Creation of digital Signature in Jharkhand

The process to create a digital signature is easy and straightforward for the average user and for enterprises to adopt. You first need a digital signing certificate, which can be acquired through a trusted Certificate Authority. After downloading and installing the certificate, you simply use the digital signing function of the appropriate document platform or application. For example, most email applications provide a “Digitally Sign” button to digitally sign your emails.

Importance of Digital Signature

As more business is conducted online, agreements and transactions that were once signed on paper and delivered physically are now being replaced with fully digital documents and workflows. However, whenever valuable or sensitive data is shared, malicious actors who want to steal or manipulate that information for their own gain are ever-present. Businesses must be able to verify and authenticate that these critical business documents, data, and communications are trusted and delivered securely to reduce the risk of document tampering by malicious parties.

In addition to protecting valuable online information, digital signatures do not disrupt the efficiency of online document workflows; in fact they typically help improve document management compared to paper processes. Once digital signatures have been implemented, the act of signing a document is easy and can be done on any computing or mobile device. And the digital signature is portable as it is incorporated in the file itself, wherever it is transmitted and on whatever device. Digitally signed documents are also easy to control and keep track of by providing the status of all documents, identifying whether or not they’ve been signed, and viewing an audit trail.

Digital Signatures Work:-

Digital signatures use public key infrastructure (PKI), which is considered the gold standard for digital identity authentication and encryption. PKI relies upon the use of two related keys, a public key and a private key, that together create a key pair to encrypt and decrypt a message using strong public key cryptography algorithms. Using both public and private keys that are generated using a mathematical algorithm to provide the signer with their own digital identity, a digital signature is generated and encrypted using that signer’s private key, and also a timestamp of when the document was signed using the key. These keys are normally stored safely thanks to the help of a trusted CA.

Here is how sending a digital signature works:

  • The sender selects the file to be digitally signed in the document platform or application.
  • The sender’s computer calculates the unique hash value of the file content.
  • This hash value is encrypted with the sender’s private key to create the digital signature.
  • The original file along with its digital signature is sent to the receiver.
  • The receiver uses the associated document application, which identifies that the file has been digitally signed.
  • The receiver’s computer then decrypts the digital signature using the sender’s public key.
  • The receiver’s computer then calculates the hash of the original file and compares the hash it has computed with the now decrypted hash of the sender’s file.

When sending out a document signed using a private key, the receiving party obtains the signer’s public key which will allow one to decrypt the document. Once the document is decrypted, the receiving party can view the unaltered document as the user intended.

If the receiving party cannot decrypt the document using the public key, then it signifies that the document has been altered, or even that the signature doesn’t even belong to the original signer.

Digital signature technology requires all involved parties to trust that the individual creating the signature has been able to keep their own private key secret. If someone else has access to the signer’s private key, that party could create fraudulent digital signatures in the name of the private key holder.

FAQs

Qus:-What if digital signature is lost?

A copy of the complaint is to be given to the RCC Admin within 24 hours of the employees reporting the loss to prevent unauthorized usage of DSC. The User, who has lost/misplaced his token will not be able to sign any document in the ITBA/HRMS application. Officer will re-apply in ITBA for new DSC. RCC-Admin.

Qus:-How many times a DSC can be used?

Once registered, no other DSC can be used, unless new DSC is registered with the server again. DSCs are issued for 1 or 2 years. After their validity has expired, they need to be issued again.
