HARDWARE BASED SECURITY APPARATUS AND SECURITY METHOD USING THE SAME

摘要

Disclosed are a hardware-based selective security apparatus and a security method using the same. The security apparatus according to an embodiment of the present invention includes: a transistor including a source electrode, a drain electrode, and a gate electrode composed of at least two electrodes; and a controller which selectively sets a security level 1 or a security level 2 by controlling a magnitude of a voltage which is applied to the gate electrode. According to the present invention, since there is no necessity of an additional space for a separate chip required by an existing hardware based security method, it is possible to obtain a recoverable hardware based security method which uses spaces usefully and has economic efficiency. Also, a recoverable security level and an irrecoverable security level are selectively applied, so that it is possible to implement an enhanced hardware-based security method.

主权项

1. A hardware-based selective security apparatus comprising:
a transistor comprising a source electrode, a drain electrode, and a gate electrode composed of at least two electrodes; and a controller which selectively sets any one of security levels having mutually different security ratings by controlling a magnitude of a voltage which is applied to the gate electrode.
