    A study to examine the superiority of CSAVK, AVK over conventional encryption with a single key
    (Science and Engineering Research Support Society ijbsbt@sersc.org, 2016) Goswami, R.S.; Chakraborty, S.K.; Bhunia, C.T.
    Time variant key is one of the great research challenges in the field of cryptography for achieving the perfect security. Automatic variable Key (AVK) has been well researched and established as an important technique to realize time variant key in achieving towards perfect security. In AVK, proposed by Bhunia, the key is made to vary from data to data or session to session that is essentially required for achieving perfect secrecy. The variable key is generated in each time a data is sent and or a session is made. The time variant key (in AVK) is found to reduce the frequency attack as seen in earlier research, while such key was in applied in AES algorithm. In the present experimental research the authors study the application of AVK & Computing & Shifting AVK (CSAVK) in RSA to examine the reducing effect of frequency attack. © 2016 SERSC.

    Dual band operation using metamaterial structure for Radio Frequency Identification (RFID) system
    (2014) Saha, R.; Bhattacharjee, S.; Bhunia, C.T.; Maity, S.
    The important functions of Radio Frequency Identification (RFID) technology are radiation and detection. So efficient antenna design and fabrication is the unique solution which perform a very crucial role for many applications. The reader and tag intense are component of the RFID system. In this paper designed has done on RFID antenna for tag and reader application, which also includes the different types of antenna (UHF application, wideband, multiband antenna) and the general consideration for design, them which are currently used for tag and reader application. In this paper we proposed a rectangular patch antenna and then designed a metamaterial structure on the patch to improve the antenna performance. � 2014 IEEE.
