Improved Efficiency for CCA-Secure Cryptosystems Built Using Identity Based Encryption
Cryptosystems Built Identity Based Encryption
2015/8/5
Recently, Canetti, Halevi, and Katz showed a general method for constructing CCA-secure encryption from identity-based encryption in the standard model. We improve the efficiency of their construction...
Algebraic pseudorandom functions with improved efficiency from the augmented cascade
improved efficiency pseudorandom functions
2015/8/5
We construct an algebraic pseudorandom function (PRF) that is more efficient than the classic Naor-Reingold algebraic PRF. Our PRF is the result of adapting the cascade construction, which is the basi...
Multiple polarized beam interferometers for array generation with improved efficiency
hexagonal array interferometry polarization
2011/5/6
A highly efficient multiple polarized beam interferometer for the generation of hexagonal array is reported. An expression for the intensity distribution is worked out using Jones’ calculus and comput...
