Our compiler achieves security in the universal composability framework, assuming access to an ideal commitment functionality, and improves over previous work achieving the same security guarantee in two ways: it uses black-box access to the underlying protocol and achieves a constant multiplicative overhead in the round complexity. As a corollary, we obtain the first constructions of adaptively secure protocols in the stand-alone model using black-box access to a low-level primitive.}, keywords = {Algorithm Analysis and Problem Complexity, computers and society, Data Encryption, Discrete Mathematics in Computer Science, Management of Computing and Information Systems, Systems and Data Security}, isbn = {978-3-642-00456-8, 978-3-642-00457-5}, url = {http://link.springer.com/chapter/10.1007/978-3-642-00457-5_23}, author = {Choi, Seung Geol and Dana Dachman-Soled and Malkin, Tal and Wee, Hoeteck}, editor = {Reingold, Omer} }
