On-line/Off-line Threshold Proxy Re-Signatures被引量：5
《Chinese Journal of Electronics》2014年第2期248-253,共6页YANG Xiaodong WANG Caifen ZHANG Lei QIU Jianbin 
supported in part by the National Natural Science Foundation of China(No.61262057,No.61063041,No.61163038);the Young Teachers’Scientific Research Ability Promotion Program of Northwest Normal University(No.NWNU-LKQN-10-22)
To improve the performance of threshold proxy re-signatures, the notion of on-line/off-line threshold proxy re-signatures is introduced. The bulk of re-signature computation can be done in the off-line phase before th...

A New On-Line/Off-Line Adaptive Antenna Array Beamformer for Tracking the Mobile Targets
《International Journal of Communications, Network and System Sciences》2011年第5期304-312,共9页Shahriar Shirvani Moghaddam Mahyar Shirvani Moghaddam 
An adaptive antenna array system adjusts the main lobe of radiation pattern in the direction of desired signal and points the nulls in the direction of undesired signals or interferers. The essential goal of beamformi...

It seems that all existing on-line/offline （threshold） signature schemes based on Shamir- Tauman＇s paradigm suffer from the key exposure problem of chameleon hashing. In this paper, we firstly propose a new efficie...
