AquaÂ(2,9-dimethyl-1,10-phenanthroline-Îş2 N,N′)bisÂ(2-hydroxyÂbenzoato-ÎşO)manganese(II) 2,9-dimethyl-1,10-phenanthroline hemisolvate
In the asymmetric unit of the title complex, [Mn(C7H5O3)2(C14H12N2)(H2O)]·0.5C14H12N2, the MnII ion is coordinated by a bidentate 2,9-dimethyl-1,10-phenanthroline (dmphen) molÂecule, one water molÂecule and two monodentate 2-hydroxyÂbenzoate anions in a distorted trigonal-bipyramidal geometry. The OH group of the 2-hydroxyÂbenzoate anion is disordered over two positions with site-occupancy factors of 0.5. The asymmetric unit is completed with by an uncoordinated half-molÂecule of dmphen, disordered about a crystallographic twofold axis. In the crystal structure, molÂecules are linked into a two-dimensional framework by O—Hâ‹ŻN, O—Hâ‹ŻO and C—Hâ‹ŻO hydrogen bonds. The packing of the structure is further stabilized by π–π stacking interÂactions involving dmphen molÂecules, with centroid–centroid separations of 3.8027 (3) and 3.6319 (3) Å
A Secure Oblivious Transfer Protocol from Indistinguishing Obfuscation
We proposed a new secure oblivious transfer protocol from indistinguishability obfuscation in this paper. Our main technical tool
is the candidate indistinguishability obfuscation introduced in [1] and
a dual-mode cryptosystem proposed in [2]. Following their steps, we
presents a new k-out-of-l oblivious transfer protocol, its realization from
DDH is described in this paper, in which we combined indistinguishability obfuscation with the dual-mode cryptosystem. The security of our
scheme mainly relies on the indistinguishability of the obf-branches ( corresponding to the two modes in dual-mode model). Our paper explores
a new way for the application of indistinguishability obfuscation
