The reference frame selection technique for an error resilience of video codec using multiple reference frames according to the present invention comprises the steps of: performing a motion estimation individually in each of the multiple reference frames so as to search a reference macroblock of the macroblock to be coded; checking the degree of match between the reference macroblock region found by the motion estimation and the intra-coded macroblock of the reference frame; and selecting the motion vector (MV) of the reference macroblock which is relatively best matched to the intra-coded macroblock of the reference frame from among the reference macroblocks found in each of the multiple reference frames.

Abstract: Disclosed are a data encryption apparatus and a data encryption method using an encryption key based on puncturing of a generator matrix. Bit values located in a column at a specific point are punctured from a generator matrix of a Reed-Muller (RM) code and thereafter, encryption of a message is performed through a public key generated by using the punctured generator matrix to defend an attack from a third party based on a structure of the RM code by change of the structure of the generator matrix, thereby solving security vulnerability caused as the existing McEliece encryption system uses the generator matrix of the RM code having a special structure as it is.
