Digital signature is quite a common term these days. In fact, with the advent of information technology, the importance of digital signature has been increasing remarkably. A digital signature is required to authenticate an electronic document, just like a handwritten signature is required to authenticate a printed or hand written document. In any document, that has legal importance, a signature is an essential part of it. As more and more documents are now used, or transferred digitally, the importance of digital signature is obvious. A digital signature actually offers more security than any kinds of handwritten signatures.

A recipient of a digitally signed message or document can verify easily that the document is dispatched only by the person having authority for the same. There remains no scope to alter, modify, or distort the signature, or the document in this process. For these positive aspects of digital signature, the importance, and volume of online transfer of documents have been increasing so rapidly. On the other hand, digital signature experts are also getting increasing importance across the industries, and government sectors. Students are sometimes given assignments on digital signature. In this matter, professional support from digital signature assignment help comes very useful.

How do the Digital Signatures Work?

In many developed countries, like the USA, and the UK, Australia, digitally signed documents get equal importance like handwritten signatures. The federal government printing office of the USA, publishes electronic forms of the budget, laws, and congressional bills with digital signatures.

The concept of digital signature is based on public key cryptography, or asymmetric cryptography. Depending on this concept, an expert can generate two mathematically linked keys, one for private key, and another public key. While creating a digital signature, a signature generating software forms a one-way hash of the data that is to be digitally signed.  The private key, then encrypts the hash. This makes a document digitally signed. The value attributed to a hash is always unique in nature. Any change in data which is digitally signed, or deleting any part of the data will automatically change the value of the hash. On the other hand, the public key helps the recipient to decrypt the data. If the decrypted hash matches with the hash provided by the public key that it is assumed that the data has been transferred as it is.

Importance of Digital Signature:

A digitally signed document has become a trend these days. It has a multiple of importance in the current context:

  • It can completely prevent forgery and tampering of documents.
