Abstract
Generating a protected content stream from a data stream provides enhanced security in short-range wireless communications networks. This protected content stream is transmitted across a first short-range communications link. In addition, information for converting the protected content stream into the data stream is transmitted across a second link. The first link may be an ultra wideband (UWB) link, while the second link may be a Bluetooth link.
Claims37
A method of providing communications security, the method comprising:
- (a) generating a protected content stream from a data stream;
- (b) transmitting the protected content stream across a first short-range communications link;
- and
- (c) transmitting across a second short-range communications link information for converting the protected content stream into the data stream.
A wireless communications device, comprising:
- means for generating a protected content stream from a data stream;
- means for transmitting the protected content stream across a first short-range communications link;
- and
- means for transmitting across a second short-range communications link information for converting the protected content stream into the data stream.
A method of providing communications security, the method comprising:
- (a) receiving a protected content stream from a first short-range communications link;
- (b) receiving from a second short-range communications link information for converting the protected content stream into a data stream;
- and
- (c) generating the data stream from the protected content stream.
A wireless communications device, comprising:
- means for receiving a protected content stream from a first short-range communications link;
- means for receiving from a second short-range communications link information for converting the protected content stream into a data stream;
- and
- means for generating the data stream from the protected content stream.
A wireless communications device, comprising:
- a controller adapted to generate a protected content stream from a data stream;
- a first transceiver adapted to transmit the protected content stream across a first short-range communications link;
- and
- a second transceiver adapted to transmit across a second short-range communications link information for converting the protected content stream into the data stream.
