چکیده
Pairing based cryptosystems can accomplish novel security applications such as ID based cryptosystems which have not been con structed e ciently without the pairing The processing speed of the pair ing based cryptosystems is relatively slow compared with the other con ventional public key cryptosystems However several e cient algorithms for computing the pairing have been proposed namely Duursma Lee al gorithm and its variant T pairing In this paper we present an e cient implementation of the pairing over some mobilephones The processing speed of our implementation in ARM processors on BREW achieves under milliseconds using the supersingular curve over F It has become e cient enough to implement security applications such as ID based cryptosystems and broadcast encryption using the pairing on BREW mobilephones

متن کاملOn Efficient Pairings on Elliptic Curves over Extension Fields
In implementation of elliptic curve cryptography, three kinds of finite fields have been widely studied, i.e. prime field, binary field and optimal extension field. In pairing-based cryptography, however, pairingfriendly curves are usually chosen among ordinary curves over prime fields and supersingular curves over extension fields with small characteristics. In this paper, we study pairings on...

متن کاملSuppression of Four Wave Mixing Based on the Pairing Combinations of Differently Linear-Polarized Optical Signals in WDM System
Data transmission in optical systems and increased transmission distance capacity benefit by using optical amplification wavelength division multiplexing (WDM) technology. The combination of four waves (FWM) is a non-linear effect in the wavelength division multiplex (WDM), when more than two wavelengths of light in a fiber launch will occur. FWM amount depends on the channel, the channel spaci...
