Apparatus and method for remotely deleting critical information

摘要

An apparatus and method for remotely deleting critical information is provided. The apparatus includes a storage unit, an identity determination unit, and a broadcast unit. The storage unit stores an input value and an output value for the input value with respect to a physically unclonable function (PUF) of each of a plurality of mobile terminals. The identity determination unit determines the identity of a corresponding mobile terminal based on received information about the loss of the mobile terminal. The broadcast unit extracts the input and output values of the PUF of the corresponding mobile terminal from the storage unit based on information transferred from the identity determination unit, and broadcasts the extracted input and output values to all the mobile terminals.

1. An apparatus for remotely deleting critical information using a physically unclonable function (PUF), the apparatus communicating with a plurality of mobile terminals over a mobile terminal network and comprising:
a storage unit configured to store an input value and an output value for the input value with respect to a physically unclonable function (PUF) of each of the plurality of mobile terminals; an identity determination unit configured to determine an identity of a lost one of the plurality of mobile terminals based on information about loss of the mobile terminal which is received from a user of the lost mobile terminal; and a broadcast unit configured to extract input and output values of a PUF of the lost mobile terminal from the storage unit based on information on the identity transferred from the identity determination unit, and to broadcast the extracted input and output values to each of the plurality of mobile terminals over the mobile terminal network so that each of the plurality of mobile terminals can delete the critical information using the extracted input and output values.
