advanced metering infrastructure (ami) is a key part of the smart grid; thus, one of the most important concerns is to offer a secure mutual authentication.  this study focuses on communication between a smart meter and a server on the utility side. hence, a mutual authentication mechanism in ami is presented based on the elliptic curve cryptography (ecc) and one time signature (ots) consists o...

We estimate the U.S. New Keynesian Phillips Curve in time-frequency domain with continuous wavelet tools to provide integrated answers three controversial issues. (1) Has short-run tradeoff been stable? (2) What has role of expectations? (3) Is there a long-run tradeoff? First, we find that is limited some specific episodes and no evidence nonlinearities or structural breaks. Second, households...
