Alignment and bit extraction for secure fingerprint biometrics
Security of biometric templates stored in a system is important because a stolen template can compromise system security as well as user privacy. Therefore, a number of secure bio...

Optimal bit allocation for low bit rate video streaming applications
Current rate control schemes in video coding standards do not have efficient frame-level bit allocation because of the inherent constraints in real-time encoding. In this paper, w...

Extracting Randomness Using Few Independent Sources
In this work we give the first deterministic extractors from a constant number of weak sources whose entropy rate is less than 1/2. Specifically, for every > 0 we give an expl...

Improved Side Channel Cube Attacks on PRESENT
: The paper presents several improved side channel cube attacks on PRESENT based on single bit leakage model. Compared with the previous study of Yang et al in CANS 2009 [30], base...
