The abbreviation EDS - electronic digital signature - is well known to those who have to deal with the issue of fast transmission of important or secret documents. In fact, it is a virtual analogue of the usual one and is designed to certify the originality of the transmitted information.
Instructions
Step 1
The main task of a digital signature is to confirm the integrity and confidentiality of letters, contracts, drawings and other documents stored on a computer, as well as to identify the identity of the owner of the document or the person who sent it.
The use of EDS has a number of advantages that make it more popular in the field of data exchange, such as the speed and low cost of document circulation, the guarantee that the document has not been read and changed by strangers. All this significantly reduces financial risks, and also contributes to the establishment of a modern and civilized business culture of communication.
Step 2
Long gone are the days when unprotected letters had to lie on the shelves of post offices for days, today you can transmit important information or conclude a profitable contract in a matter of minutes, no matter how far away the subscribers are. EDS is protected by law and is official, recognized along with the usual way of signing a document, it is tied to the details of its owner and cannot be forged.
Step 3
The operation of an EDS is based on the interaction of a public and a private key, that information in electronic form, which, when compared, confirms the authenticity and invariability of the document. The signature itself can be attached and detached, depending on whether the file with the signature is transmitted separately or together with the main data, in addition, the signature can be placed inside the letter itself. The public key, stored on any type of electronic media, is with the sender, while the private key itself, which is valid only in conjunction with the certificate transmitted along with the message itself, is the prerogative of the recipient. In case of doubts about the safety and originality of the signature or document, the letter cannot be viewed corny.
Step 4
It is interesting that the electronic digital signature itself was developed back in 1976, then no one would have thought that the modern system of government orders and electronic trading would be completely built on this reliable and easy-to-use scheme. In Russia, a similar signature appeared in 1994, the main sphere of its application at that time was the country's state security system. Today, EDS is a powerful information object widely used by enterprises and organizations for the transmission of important financial statements and personal use.
