Abstract: Disclosed is a method of generating secret information on the basis of a ring oscillator. According to an embodiment of the present disclosure, there is provided an apparatus for generating secret information on the basis of a ring oscillator, the apparatus including: multiple PUF information generation units each including at least one ring oscillator cell and generating physically unclonable function (PUF) information generated by the at least one ring oscillator cell; a phase checking unit cross-checking phases for the multiple pieces of the PUF information that are output from the multiple PUF information generation units, respectively; and a secret key generation unit outputting secret key information based on a result of comparing the multiple phases received from the phase checking unit.

Abstract: The present disclosure relates to a tactile emotion recognition method and device, and is directed to assigning an impedance value to each object in a virtual space; inducing virtual force using displacement between the object and a user's body in the virtual space; inducing a signal, which causes a signal of a sensory nerve to be fired, with a value corresponding to the virtual force; stimulating a location where the sensory nerve is located temporarily or over time; and generating feedback in the virtual space based on a stimulation result.

Abstract: Provided is a module and method for transmitting information using a wireless hidden signal, which is capable of transmitting important information data requiring extreme security using a wireless hidden signal, and allowing the important information to be detected and distinguished by only promised transmitting/receiving parties so that the possibility of the wireless hidden signal being discovered can be minimized and security can be enhanced. The module for transferring information using a wireless hidden signal includes: a hidden formatting unit configured to generate a transmission data frame structure based on data that needs to be wirelessly transmitted; a hidden encoding unit configured to encode the generated transmission data frame structure to generate and output a hidden encoded bit stream; and a hidden modulation unit configured to convert the output hidden encoded bit stream into a wireless signal in a wireless transmission format.
