Anonymous channels or similar techniques that can achieve sender's anonymity play important roles in many applications. However, they will be meaningless if cryptographic prim...
In this paper, we introduce a randomized bit encoding scheme that can strengthen the privacy protection on RFID tags. This scheme is used together with the backward channel protec...
Abstract--This paper addresses the problem of joint optimization of transmit beamforming and space-frequency (SF) coding for MIMO-OFDM systems with spatial correlation feedback in ...
This paper proposes the first inner product encryption (IPE) scheme that is adaptively secure and fully attribute-hiding (attribute-hiding in the sense of the definition by Katz...
In this paper, we analyze the role of the social group in a Ubiquitous Computing (Ubicomp) environment as a source of contextual information. A model is presented to address the s...
