1. An integrated circuit device comprising:
- a processor;
one or more computer-readable media;
computer-readable instructions resident on the one or more computer-readable media which, when executed by the processor, implement a method comprising;
selecting a set of defined commands each of which has an inherent function that is not associated with authentication;
transmitting the selected set of defined commands between the integrated circuit device and a receiving/sending unit effective to enable the receiving/sending unit to authenticate the integrated circuit device using the transmitted set of defined commands.

7. 1 An integrated circuit device comprising:
-
a processor;
one or more computer-readable media;
computer-readable instructions resident on the one or more computer-readable media which, when executed by the processor, implement a method comprising;
transmitting a plurality of data processing commands between a first identity that is to be authenticated and a second identity that is to authenticate the first identity, the data processing commands having an apparent data processing function and a hidden function, the apparent data processing function not being associated with authenticating the first identity, the hidden function being associated with authenticating the first identity. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. An integrated circuit device comprising:
-
a processor;
one or more computer-readable media;
computer-readable instructions resident on the one or more computer-readable media which, when executed by the processor, implement a method comprising;
establishing communication between a pair of authenticatable identities, one of which is to be authenticated by the other;
allocating a portion of the communication to steganographic communication; and
authenticating the one identity using the steganographic portion of the communication. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)

22. An integrated circuit device comprising:
-
a processor;
one or more computer-readable media;
computer-readable instructions resident on the one or more computer-readable media which, when executed by the processor, implement a method comprising;
defining a plurality of unencrypted authentication structures, each authentication structure containing at least one command;
associating each authentication structure with an identity that is to be authenticated;
establishing an unencrypted dialog between a pair of identities;
incorporating an authentication structure into the unencrypted dialog, the authentication structure being capable of being evaluated for authenticating an identity if the authentication structure corresponds to the identity seeking to be authenticated. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29)

30. An authentication method comprising:
-
defining an authentication network having a plurality of authentication paths;
receiving communication from an identity that is to be authenticated, the communication having a purpose that appears to be unrelated to authentication;
using the communication from the identity to follow an authentication path through the authentication network; and
authenticating the identity if the authentication path leads to a valid authentication state for the identity.

31. An integrated circuit device comprising:
-
a processor;
one or more computer-readable media; and
an authentication table stored in the one or more computer-readable media to hold a plurality of identities and to correlate data-processing commands with each identity, the data-processing commands for each identity having a unique identity-specific organization which, when recognized, can be used to authenticate an associated identity. - View Dependent Claims (32, 33, 34)
