Abstract(in English)	In ths paper, we propose the verification scheme for the third party of the ID based public-key cryptosystem with signature which is proposed at ISEC, March 2003. We also propose the more efficient ID based public-key cryptosystem with signature that can reduce the data size of teh ciphertext. Moreover we estimate the efficiency of our proposed cryptosystems compared with the cryptosytems which are the conventional ID based signature scheme and encryption schemes. Finally we show that the reduction scheme of the verification for the ID based signature with scalar key which is proposed at ISEC, March 2003 is efficient.
