Abstract
A security token, a security system and a method for authenticating a client are disclosed. The security token including a one-time password mechanism, for rendering one-time password functionality; a public-key mechanism, for rendering public-key functionality with respect to the one-time password functionality; and wired communication means with a host, for connecting the security token to the host and for providing the security token the power supply required for operating at least the public-key mechanism, thereby enabling rendering one-time password functionality and/or public-key functionality by the security token.

8. A one-time password security token, for securely providing a one-time value to a host system, said one-time password security token comprising:
-
means for generating said one-time value;
a public-key infrastructure mechanism, for performing public-key functionality with respect to said one-time value; and
communication means for connecting said security token with said host and for providing said encrypted one-time value to said host. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A security system comprising:
-
at least one security token comprising;
a one-time password mechanism, for rendering one-time password functionality;
a public-key mechanism, for rendering public-key functionality with respect to said one-time password functionality; and
communication means for connecting said security token to said host and for providing to said security token the power supply required for operating at least said public-key mechanism;
a host system, comprising;
a one-time password mechanism, corresponding to the one-time password mechanism of said at least one security token, for rendering one-time password functionality;
a public-key mechanism, corresponding to the public-key mechanism of said at least one security token, for rendering public-key functionality;
communication means, corresponding to the communication means of said at least one security token, for communicating with said at least one security token and for providing to said token the power supply required for operating at least the public-key mechanism of said security token. - View Dependent Claims (17, 18)

19. A method for authenticating a client by a host system, said method comprising:
at said client side;
(a) generating a first one-time value;
(b) performing public-key functionality with respect to said one-time value;
(c) providing said value to said host system;
at said host system side;
(d) performing public-key functionality which corresponds to the public key functionality performed at step (b) with the provided value;
(e) generating a second one-time value in substantially the same manner as said first one-time value is generated;
authenticating said client by the correspondence of said second value to said first value. - View Dependent Claims (20, 21, 22)
