Predominance of Digital Signature


Digital Signature provides assurance to the proof about your origin, transactions, identity and using this one can acknowledge consent by the signer. This technique, to an extend helps to prevent impersonation in digital world and also helps to avoid tampering of handwritten signature and stamped seal. So, as a result digital signature is a method to confirm integrity and authenticity of software, digital documents and messages. Nowadays all around the world adopts the concept of digital signature instead of conventional handwritten signatures. The US government now legally accepts the electronic representation of their budgets, congressional bills and their laws using digital signature. A digital signature can be used with either encrypted or unencrypted messages, and the receiver can ensure the genuinity of the sender’s message. The digital signature is always distinctive for the signer and the document. This process is called non-repudiation. This makes the signer not to deny the signed document as not signed. The new mailing technologies now use the concept of digital signature and digital certificate and use for validating incoming mails and signing of outgoing mails. Digital signature and digital certificates are confused to be same. But it is not. Digital certificate are electronic documents that includes digital signatures issued by a certifying authority. A digital signature which is authenticated provides cryptographic proof that the stated entity signed the document. A digital signature only authenticates the signed data which may be a document or representation of document, if it is unaltered. If the document undergoes a modification, the digital signature fails to authenticate.

    Electronic Signature Online certificates bind a public key to an electronic signature and recognize it. A certificate containing a public key identifies an individual.

Centuries back the way of reaching to a mutual agreement was by signing contracts using several physical seal methods. As technology evolved the signing agreements become digital, this made the process more secure and safe. The idea of digital signature was a contribution by Ronald Rivest, Len Adleman and Adi Shamir by their invention of RSA algorithm on 1977 which was the earliest digital signature method. The method of digital signatures were accepted legally up in court and have equal acceptance as same as that of a normal signature in a document. A digital signature certificate is represented using a digital key. This digital key is provided by the certifying authority which helps to verify the credentials of a person which helps to identify that particular person. These signatures are generated using public key encryption method. The major details included in a digital signature certificate is the user’s name, email, pin code, country and the date in which certificate issue

How does a digital signature works?

The digital signature is a digital method of ensuring the correctness of the identity of people by saving time and cost to a great extent. The digital signature method uses public-key cryptography. This method is also known as asymmetric cryptography. Using the public key encryption algorithm, one can generate two keys which are known as the public key and private key. The digital signature works with the help of these two mutually authenticated keys. Here the person who is creating the digital signature uses the private key to encrypt the document which is to be signed and this document can only be decrypted using the public key of the signer. This way is used to do the authentication of digital signatures . The digital signature method makes all the parties believe that the created digital signature by the individual is kept secret and does not make the fraudulent mechanisms by the private key holder. A one-way hash of digital data to be signed is generated when one tries
