Computer Digital signature And Alternative password devices

A digital signature or electronic signature is an encryption technique, while ensuring the documents, the identity of the author of the report and that the content of the document has not been altered.

Simple One your private key and all users can try to encrypt to decipher with the public key of A. If the result of the decryption is somewhat readable, this means that the document is actually encrypted with the private key of A and is used therefore it from A; On the other hand, if the result can not be read, which means that the encryption was not made with the private key of A.

added a personal device for important activities, such as digital signatures or operations of the Bank, as a rule, rather than the system login and password standard. The usual password is personally remembered by the user and a personal device represents the second part of the password. This device can be a smart card, such as national health card to be inserted into a card reader or USB token, and enter the program site or the second half of the password that is stored inside the object. Alternatively, the second part of the password is an OTP password generated each time by a telephone call to the mobile phone user or displayed on a small sample of a time (which can be introduced either not inserted or USB) connection, which for the site password required is clearly synchronized. This second great advantage of this system is that even if the two parts of the password intercepted or guess the second part can only use the time, and expire after a few seconds.
