Digital Verification is Need of The Hour

Author: Abovethefoldwriter Mumbai

As more and more businesses go online the need for digital verification arises greatly. Unlike brick-and-mortar transactions where interacting persons are visible to each other and can be verified in the virtual world that is not possible. E-Governance has become active in a big way and interacting businesses need to verify their authenticity for all e-transactions to the dispensations. Earlier all sorts of signatures chiefly electronic signatures were used but these were not 100 % foolproof. This fact was thus hampering e-governance while businesses found it impossible to receive the authentication required. In cryptography, digital signatures are server-based signatures but unlike the PKI systems here a public server is involved.

Enter Digital Signature Certificates

Trials and errors have been going on for a long time for a foolproof authentication system to emerge. And eventually, digital signatures made an entry. This is a cryptological technology that made an entry using a key pair system. The private key generated by hash algorithms helped encrypt electronic documents and messages. The encrypted messages and documents were then decrypted by the use of the public key which acted as a decoder. Any manipulation on the way was instantly caught by matching the hash generated by the private key. Not only this, the system has created a non-repudiable and legal tender system. The digital signature thus fulfills the e-verification of transacting parties in the form of eID. It is here that the use of PKI-based digital certificates comes into the picture. Known as digital signature certificates they help manage electronic identity.

Digital Signature Certificates are issued by CAs in India. They are also known as certifying authorities. They are authorized by CCA or Controller of Certifying Authorities under the information technology act in India.

Validating Digital Signature

For this purpose, you need three elements. There are:

  • Data Sent
  • The Signature
  • Public Key

The public key in all instances should be generated by the corresponding private key. Software is used to decrypt the digital signature using a public key. Thus, the original document is recovered by the receiver in a human-readable form. In this case, the pre and post-encryption document has should match this is done by using the software. If both the hash generated by hash algorithms match it means no manipulation has taken place online.

Signing Servers

The signing servers like ADSS for example help digitally sign documents, data, and transactions. This is vital for e-governance and businesses for the implementation of e-transactions. Thus ADSS help in the eseal and esign process. Using the signing servers one can even code time stamps and e-passports. Most of the signing servers are secure and have capabilities for bulk signing and incorporate plug-ins for creating varied digital signatures.

As technology advances the systems incorporated for creating, verifying, and decrypting digital signatures also increase. But the PKI or public key infrastructure remains highly popular. In the whole process, digital signature certification is of utmost importance to create trust. The use of DSC is growing fast all over the commercial World. You can use DSC for a price charged by the CA or the Certifying Authority in charge of issuing DSC. Most of the DSC expire after one year and have to be renewed. You can buy DSC online with ease or through a CA website. It is delivered within five days after the requisite documents are sent and a video interview takes place.
