摘要： A method of providing continuous authentication in a contactless environment is provided. The method includes providing a reader having a contactless interface, as well as a device, operable to communicate with the reader. The method further includes the steps of receiving at the reader a first authentication request from the device, and communicating from the reader a second authentication request to a secure transaction service. The secure transaction service holds authentication credentials relating to the device. Authentication credentials relating to the device are received at the reader from the secure transaction service, and the reader provides continuous authentication based at least in part on the authentication credentials received from the secure transaction service.

摘要： The phase shifted (PS) transmitter provides substantially linear amplification from two non-linear amplifiers by decomposing the original signal into two constant envelope signals with varying phases. The generation of the two constant envelope signals does not require the use of a signal component separator (SCS) or a reference signal generator. The phase shifted transmitter generates directly the required constant envelope, varying phase signals. This eliminates stringent requirements on the circuitry and allows the use of non-linear highly efficient power amplifiers in the transmitter. When the two above mentioned signals are combined, they constructively and destructively interfere to re-form an amplified form of the original signal, which is to be transmitted via an antenna.
