What is a digital signature?
A digital signature is like a physical signature in the digital world. Basically, when someone signs something using their natural signature, the same applies to their electronic files in public tenders and online transactions. All that the digital process recquires is a USB token.
What exactly is the role of the Digital Signature?
The use of this type of signature replaces the need to go through tedious paperwork and validate documents. The digitally signing process recquires a USB token and the corresponding software. The process is pretty simple. First of all, the sender creates the message or document. Afterwards, he then uses a token, alternatively called a private key, to attach the user’s signature. This ensures that it’s practically impossible for anyone else to sign with your name.
A Digital Signature offers peace of mind that an electronic document has not been tampered with. Signing digitally with a USB Token makes it even more reliable because of its portability. The question is how verification happens. The recipient of a document or message receives a signature showing the user’s name and status.
Similarly, the recipient of the message sends it first and then looks up the sender’s public key. This process is done automatically and there are public keys available electronically via the PKI. The public key is a vital tool to confirm that a sender’s signature made digitally is genuine.
