The underlying figure schematizes the functions of
the key:
a) User’s recognition: with a particular process
of call-answer the server verifies the presence of the key on the “client” and
subsequently the data contented in it
and only in case of positive verifications it provides to authorize the access
to the site.
b) Installation of a protected
and encoded connection: if the preceding phase is overcome it is established a of
transmission-receiption session that codifies the login data or all the data in
transit between server and client and viceversa.
All happens in transparent manner since the
component that converses with the server to recognize the presence of the key
and it’s data, an Active-X, is installed automatically on the pc at the first
connection to the protected pages.
The second figure shows the scheme of data encoding:
the key uses an encrypting algorithm called blowfish 256 bits for dates transmission and
receiving, that can be used in the same time with the SSL protocole, to increase
the security subsequently (even if it wouldn’t be necessary :-) ), using connections of the
type https://www.site.com connection types as in the banking gateways.
The last figure evidences as the key codifies and
protects the data not only in the transmission but also inside to avoid any
stealing attempt of the access parameters to the site, directly from the pc
where it is used or with any other electronic method.
The used algorithms in this case are 3DES and l AES1
