Authentication platform and related method of operation

An authentication platform implemented in a portable integrated device including the authentication platform and a client device storing trusted information, the authentication platform comprising:

• an authentication unit that receives input data from a user and authenticates the user based on the input data;
• a control unit that enables communication between the client device and an authentication host controlling access to a secured entity as a consequence of successful authentication of the user by the authentication unit, and that communicates with the authentication host requesting a time delay while the authentication unit authenticates the user;
• a first interface that communicates with the authentication host using a protocol associated with the client device;
• and
• a second interface that communicates with the client device using a protocol associated with the authentication host,
• wherein the authentication host is disposed separate from the portable integrated device and is configured to authenticate the client device based on the trusted information.

An authentication platform implemented in a portable integrated device including the authentication platform and a client device storing trusted information, the authentication platform comprising:

• an authentication unit that receives input data from a user and authenticates the user based on the input data;
• a control unit configured to;
• (1) enable communication between the client device and an authentication host controlling access to a secured entity as a consequence of successful authentication of the user by the authentication unit,
• (2) capture and store a first message generated by the client device upon a first powering up, and transmit the stored first message to the authentication host as a consequence of a first successful authentication of the user by the authentication unit, and
• (3) capture and store a second message generated by the client upon a second powering up subsequent to the first powering up device, and replace the stored first message with the second message upon determining that the second message is different from the stored first message;
• a first interface that communicates with the authentication host using a protocol associated with the client device;
• and
• a second interface that communicates with the client device using a protocol associated with the authentication host,
• wherein the authentication host is disposed separate from the portable integrated device and is configured to authenticate the client device based on the trusted information.

A method of operating an authentication system including an authentication host controlling access to a secured entity, and a portable integrated device separately disposed from the authentication host and including an authentication platform and a client device, wherein the client device stores trusted information that enables the authentication host to recognize the client device, the method comprising:

• receiving input data from a user via a user interface of the authentication platform;
• enabling communication between the client device and the authentication host through the authentication platform as a consequence of authenticating the user, wherein the authentication platform communicates with the authentication host using a first protocol recognized by the authentication host as belonging to the client device, and communicates with the client device using a second protocol recognized by the client device as belonging to the authentication host;
• and
• transmitting a delay request from the authentication platform to the authentication host while authentication of the user is pending.
