امنیت اطلاعات ,

یکشنبه 4 دی 1384


• A digital certificate is an electronic "credit card" that establishes your credentials when doing business or other transactions on the Web. It is issued by a certification authority (CA). It contains your name, a serial number, expiration dates, a copy of the certificate holder's public key (used for encrypting and decrypting messages and digital signatures), and the digital signature of the certificate-issuing authority so that a recipient can verify that the certificate is real

• A form of personal identification that can be verified electronically. Only the certificate owner who holds the corresponding private key can present a certificate for authentication through a Web browser session. Anyone can verify that the certificate is valid by using a readily available public key.

• A Digital Certificate issued by a Certificate Authority certifies that a merchant and a particular website are connected, just as a photo on your driver's licence connects your identity with your personal details. A digital certificate verifies to the shopper that the virtual store is actually associated with a physical address and phone number which can increase the shoppers confidence in the authenticity of the merchant.


• A digital certificate is a special message signed by a certificate authority that contains the name of some user and their public key in such a way that anyone can "verify" that the message was signed by no one other than the certification authority and thereby develop trust in the user's public key.

• Online identification authenticates a consumer, merchant and a financial institution. Digital certificates used to encrypt information exchanged in SET transactions. A certificate is a public key digitally signed by a trusted authority (the financial institution) to identify the user of the public key.

• A digital certificate is a special kind of message that contains information about who it belongs to, who it was issued by, a unique serial number or other unique identification, valid dates, and an encrypted "fingerprint" that can be used to verify the contents of the certificate. Digital certificates are issued by trusted third parties, known as Certificate Authorities. ...

• A digitally signed statement that binds the identifying information of a user, computer, or service to a public/private key pair. A digital certificate is commonly used in the process of authentication and for securing information on networks.

• an attachment to an electronic message that allows the recipient to authenticate the identity of the sender via third party verification from an independent certificate authority. Digital certificates are used to identify encryption and decryption codes between message senders and recipients.

• An electronic document used to verify the identity of a user, server or other End Entity. Digital Certificates are used to verify that a user sending a message is who he, she or (in the case of other End Entities) it claims to be and to provide the recipient with a means to encode a reply.

So  it is a part of our life and business and we have to learn how to live with it. It makes our buisines more easier and faster then ever before.
