Abstract
A system and method are provided for securing data transmission during operation of a wireless networked communication system comprising a base station and one or more remote devices. The base station generates an encryption key, encodes the key as an acoustic signal, and transmits the signal. The acoustic signal is received by all co-located remote devices of the communication system, and decoded to extract the encryption key. Subsequent communication transmissions between and among the base station and the remote device are encrypted using the encryption key to prevent electronic eavesdropping.
Claims20
A method for secure data transfer in a wireless networked communication system, comprising the steps of:
- generating an encryption key within a first device of the communication system;
- encoding the encryption key to form an encoded signal;
- transmitting the encoded signal to a second device of the communication system remote from the first device;
- decoding the encoded signal at the second device to extract the encryption key;
- and
- using the encryption key to encrypt and decrypt data for subsequent wireless transmissions between the first and second devices.
A system for secure data transmission within a wireless communication system, comprising:
- a first device of the communication system, the first device having an encryption key generator for generating the encryption key and a signal transmitter for transmitting an encoded signal representative of the encryption key;
- and
- a second device of the communication system, the second device having a signal sensor for receiving the encoded signal from the first device and a decoder device for extracting the encryption key from the encoded signal, the encryption key being used to encrypt data being transmitted between the first and second devices.
A system for secure data transmission within a wireless communication system, comprising:
- means for generating an encryption key within a first device of the communication system;
- means for encoding the encryption key to form an encoded signal;
- means for transmitting the encoded signal to a second device of the communication system remote from the first device;
- means for decoding the encoded signal at the second device to extract the encryption key;
- and
- means for using the encryption key to encrypt and decrypt data for subsequent wireless transmissions between the first and second devices.
