At our world, no letter is valid without a signature, but each signature is not reliable, too. In traditional world, each person marks a written text on a paper by a sign such as a signature, seal or fingerprint to verify that text, otherwise it won’t be approved. In recent years due to advances in information technology, we have seen change of letter and paper documents’ styles into electronic documents and files that are created and processed by various organizations and software. We need a mechanism similar to traditional signature in cyberspace to validate this type of documents. Since computers and smart machines of electronic world know nothing except numbers; this type of signature must also be in the form of numbers but in a way that isn’t available to someone other than one’s own. Digital signatures is a cryptographic technique based on asymmetric cryptography as well as using asymmetric keys that converts connections, documents and generally all data into code according to signature owner’s request. Unlike traditional signatures, this sign nor has the appearance neither is visible, but it is a bit string of ones and zeros and can be validated by software and system. Digital signature is able to offer some tasks such as authentication, document verification and non-repudiation. Digital signature indicates that the apparent sender is the very original sender; however, in the electronic world like the real world, there is the possibility of fraud. Suppose, an email is sent from a seller to a manufacturer in which a large number of manufacturer products is requested. Now, buyer can’t accept this letter accuracy without reliable sign of manufacturer, also after a while, he can deny sending the letter. To use digital signs, we need a foreign central called CA (certificate authority) to verify the person’s name, software or site. After qualification verification, a digital signature certificate is issued for applicant. For example, electronic exchange sites, such as virtual stores, guarantee accuracy and reliability of exchanges for clients because they have this certificate. This certificate which has all characteristics of the certifier, date of issue and expiry date confirms the accuracy of exchanges; however, buyers also must obey security issues such as enough knowledge about Certifier Company, contacting to that company, if necessary and earning some information about the accuracy of issued certificate.

How does this signature work?

Digital signature methods are based on an encoding and according to asymmetric keys and hash. Asymmetric encoding uses public and private keys. It should be noted that each key is a set of numbers and characters. A public key is a key that is sent along with information to other party and he can have this key, but private key should never be given to anyone, somehow it is your password and used to encode information during connection to a specific person.

In fact, the unique series of numbers and letters is confirmed when a key is verified. This verification was placed at attachment of certificate. During the selection a key over a key ring, the certificate (license) of key can be observed and as previously mentioned, the time of this certificate validity and other parameters, such as name of person for who it was issued also are stated in it. Algorithms which are using for this purpose are so various, but RSA and Elgamal cipher algorithms and SHA, 5MD and hashing algorithms are the most common and widely used ones.

Iranian model of electronic security

In our country, many actions have been done by universities, government agencies and private firms in order to achieve e-government and the urgent need of this sector for security, both in public sector and admin affairs such as automation and e-commerce. Recently, root certificate authority center of our country has attempted to issue certificate for applicants of electronic certificates and digital signature mechanisms. In this regard, Payam Pardaz Engineering Co. has attempted in recent years to design and construct Keya3 Token which supports completely the digital sign mechanism and private key maintenance in a secure manner. It also can be used in different systems.
