| 20120093308 | APPARATUS AND METHOD FOR GENERATING RANDOM DATA - Provided are an apparatus and method for generating random data to be used when masking data to be ciphered. The apparatus for generating random data according to an exemplary embodiment of the present invention is an apparatus for generating a random function using a physically unclonable function (PUF) logic. The apparatus for generating random data logically operates first data and second data using two different types of logic gates, and inverts the logical operation values selected from the logically operated first data and second data every odd sequence and then, inputs them as the second data again, thereby making it possible to form the output data as the random data. The present invention is applied to a data encryption apparatus for encrypting data to prevent a side channel attack. | 04-19-2012 |
| 20110116740 | OPTICAL COMMUNICATION DEVICE HAVING DIGITAL OPTICAL SWITCHES - Provided is an optical communication device including optical switches. The optical communication device a first multi-mode core disposed on a substrate, the first multi-mode core extending in a first direction and second multi-mode cores disposed on a substrate, the second multi-mode cores parallelly extending in a second direction non-parallel to the first direction to intersect the first multi-mode core. The heaters respectively intersect intersectional regions between the first and second multi-mode cores. | 05-19-2011 |
