US10021081B2	Method and apparatus for trust-based, fine-grained rate limiting of network requests A method and apparatus for fine-grained, trust-based rate limiting of network requests distinguishes trusted network traffic from untrusted network traffic at the granularity of an individual user/machine combination, so that network traffic policing measures are readily implemented against untrusted and potentially hostile traffic without compromising service to trusted users. A server establishes a user/client pair as trusted by issuing a trust token to the client when successfully authenticating to the server for the first time. Subsequently, the client provides the trust token at login. At the server, rate policies apportion bandwidth according to type of traffic: network requests that include a valid trust token are granted highest priority. Rate policies further specify bandwidth restrictions imposed for untrusted network traffic. This scheme enables the server to throttle untrusted password-guessing requests from crackers without penalizing most friendly logins and only slightly penalizing the relatively few untrusted friendly logins.

Alternatively, a transistor having normally-off characteristics which includes an oxide semiconductor is provided. The transistor includes a first conductor, a first insulator, a second insulator, a third insulator, a first oxide, an oxide semiconductor, a second conductor, a second oxide, a fourth insulator, a third conductor, a fourth conductor, a fifth insulator, and a sixth insulator. The second conductor is separated from the sixth insulator by the second oxide. The third conductor and the fourth conductor are separated from the sixth insulator by the fifth insulator. The second oxide has a function of suppressing permeation of oxygen as long as oxygen contained in the sixth insulator is sufficiently supplied to the oxide semiconductor through the second oxide. The fifth insulator has a barrier property against oxygen.
