  • Patent number: 9503992
    Abstract: Different target transmit powers are determined for different wireless transmissions from a wireless device. The target transmit power of a wireless transmission may depend upon whether any transmitters other than the device to which the wireless transmission is to be sent are within range of the sending wireless device. The target transmit power of a wireless transmission may be based, at least in part, on a current location of a device to which one or more frames carried by the wireless transmission are addressed. The target transmit power of a wireless transmission may be based, at least in part, on confidentiality of data carried by the wireless transmission.

  • Publication number: 20110321171
    Abstract: A system includes a first wireless-enabled device that transparently stores confidential information and a second wireless-enabled device that stores the same confidential information. The confidential information is to be used to secure a wireless communication link between the first device and the second device. One or both of the first device and the second device is to delete the confidential information upon fulfillment of one or more conditions related to the communication link.

  • Publication number: 20090276626
    Abstract: A reader device includes a housing for receiving a smart card, a processor in electronic communication with an integrated circuit chip of the smart card when the smart card is received in the housing, a wireless communications device in electronic communication with the processor for enabling the reader device to transmit first encrypted information wirelessly and to receive second encrypted information wirelessly, and a memory in electronic communication with the processor that includes one or more routines executable by the processor. The one or more routines include a cryptographic module adapted to encrypt first information to create the first encrypted information and decrypt the second encrypted information to obtain second information. In addition, a communication system that includes the reader device and a computing device, wherein the reader device and computing device are able to wirelessly exchange information in a secure manner.
