This memo specifies two elliptic curves over prime fields that offer a high level of practical security in cryptographic applications, including Transport Layer Security (TLS). These curves are intended to operate at the ˜128-bit and ˜224-bit security level, respectively, and are generated deterministically based on a list of required properties.
We present our experience with QUIC, an encrypted, multiplexed, and low-latency transport protocol designed from the ground up to improve transport performance for HTTPS traffic and to enable rapid deployment and continued evolution of transport mechanisms. QUIC has been globally deployed at Google on thousands of servers and is used to serve traffic to a range of clients including a widely-used web browser (Chrome) and a popular mobile video streaming app (YouTube). We estimate that 7% of Internet traffic is now QUIC. We describe our motivations for developing a new transport, the principles that guided our design, the Internet-scale process that we used to perform iterative experiments on QUIC, performance improvements seen by our various services, and our experience deploying QUIC globally. We also share lessons about transport design and the Internet ecosystem that we learned from our deployment.
This study examines rural urban differences in the use of various information technologies (IT) applications by physicians in the ambulatory setting. Findings suggest that no differences exist between rural and urban physicians with respect to the use of a computer (77.4 vs 81.4; p=.144) or with the availability of an Internet connection (95.0 vs 96.5; p=.249) in the office. However, rural physicians were significantly less likely than urban doctors to indicate using e-mail with patients (7.9 vs 17.2%; p<.001) and slightly less likely to use a personal digital assistant (PDA) (32.3 vs 37.9; p=.091). Rural doctors were significantly less likely to indicate routinely using an electronic health records (EHR) system (17.6 vs 24.1; p=.020). EHR differences between rural and urban physicians were not significant (p=.124) in multivariate analyses and were explained away by practice size (p<.001) and practice type (p=.015). Most barriers to EHR did not differ between rural and urban physicians. However, rural physicians more commonly cited barriers associated with temporary disruptions to productivity or disruptions in access to records when computers systems fail. In sum, EHR use and patient e-mailing is less common in rural areas. While much of this variability can be explained by rural practice characteristics, these findings illustrate the need for further efforts to identify and alleviate barriers and encourage health IT adoption in rural areas.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
