Hybrid Damg?rd Is CCA1-Secure under the DDH Assumptiontem is CPA-secure, the used MAC is unforgeable, the used key-derivation function is secure, and the underlying group is a DDH group. The new cryptosystem is the most efficient known CCA1-secure hybrid cryptosystem based on standard assumptions.

Cryptanalysis of Short Exponent RSA with Primes Sharing Least Significant Bitsrmat factoring on LSBS-RSA, which claims that . and . cannot share more than . least significant bits, where . is the bit-length of .. In conclusion, it is a trade-off between the number of sharing bits and the security level in LSBS-RSA. One should be more careful when using LSBS-RSA with short exponents.

Keyword Field-Free Conjunctive Keyword Searches on Encrypted Data and Extension for Dynamic Groups propose a scheme of keyword field-free conjunctive keyword searches on encrypted data, which affirmatively answers an open problem asked by Golle . at . 2004. Furthermore, the proposed scheme is extended to the dynamic group setting. Security analysis of our constructions is given in the paper.

Analysis and Design of Multiple Threshold Changeable Secret Sharing Schemest. First, we compute a theoretical bound on the information and security rate for such a secret sharing. Second, we show how to achieve multiple threshold change for a Chinese Remainder Theorem like scheme. We prove that the parameters of this new scheme asymptotically reach the previous bound.

Pascalis Raimondos-M?ller,Alan D. Woodlande pairing computation is very demanding. Still, pairing-based non-interactive key establishment requires minimal communication and at the same time enjoys excellent properties when used for key distribution.
