Abstract

An information handling system (IHS) includes a transceiver for receiving a wireless transmission communication packet, a physical channel for communication, a filter to block data and a processor to receive unblocked data to obtain a parameter from the wireless communication packet unblocked to determine a frequency hopping sequence and an initial link key for trusted communication with the IRS.

Claims

1. ) A method for establishing an initial link key between a first device and a second device comprising:

blocking, at the first device, at least a portion of data in a data packet transmitted from the second device, to obtain unblocked data;

determining a frequency hopping sequence using at least a portion of the unblocked data;

establishing a connection on a physical channel between the first device and the second device with the frequency hopping sequence; and

establishing an initial link key using at least a portion of the unblocked data.

2. ) The method of claim 1 further comprising:

performing a challenge-response authentication process between the first device and second device with the initial link key.

3. ) The method of claim 1 wherein the initial link key is based on at least one of:

a Personal Identification Number, a BLUETOOTH device address, a random number and a length of the Personal Identification Number.

4. ) The method of claim 1 wherein blocking data further comprises extracting only a BLUETOOTH device address from the data packet.

5. ) The method of claim 1 wherein blocking data further comprises quarantining at least a portion of the received data packet and extracting a BLUETOOTH device address.

6. ) The method of claim 1 wherein at least a portion of the unblocked data is used to determine one of a BLUETOOTH device address, a channel access code, a device access code, a crock parameter, a device class, a page scan mode, a BLUETOOTH device name, a tower address part, an upper address part, and a non-significant address part.

7. ) A set of application program interfaces embodied on a computer readable medium for execution by a processor included in a first device for establishing a trusted communication link with a second device comprising:

a first interface that receives data from a first portion of a wireless data packet transmitted from the second device to obtain at least a portion of an unblocked packet data, wherein a second portion of the data in the wireless data packet is blocked packet data;

a second interface that receives data extracted from at least a portion of the unblocked packet data to determine a frequency hopping sequence for establishing a communication link with the second device;

a third interface that receives data from a connection on a physical channel associated with the communication link; and

a fourth interface that receives an initial link key for establishing the communication link as a trusted communication link between the first device and the second device, wherein the initial link key is associated with at least a portion of the unblocked packet data.

8. ) The set of application interface programs according to claim 7 further comprising a fifth interface to receive data from a challenge-response authentication interaction between the first device and second device, the challenge-response authentication using the initial link key.

9. ) The set of application interface programs according to claim 7 wherein the second interface receives quarantined data from at least a portion of the blocked packet data.

10. ) The set of application interface programs according to claim 7 wherein the second interface receives data associated with a BLUETOOTH device address extracted from at least a portion of the unblocked packet data.

11. ) The set of application interface programs according to claim 7 wherein the initial link key is associated with at least one of:

a Personal Identification Number, a BLUETOOTH device address, a random number and a length of the Personal Identification Number.

12. ) An information handling system (IHS) comprising:

a transceiver configured to receive a wireless transmission communication data packet;

a physical channel for communication of data in the data packet; and

a processor configured to process instructions to block at least a portion of data in the wireless communication packet wherein unblocked data is used to determine a frequency hopping sequence and an initial link key for trusted communications.

13. ) The system of claim 12 wherein the initial link key is based on one of i) a BLUETOOTH device address, ii) a PIN code, iii) a length of a PIN and iv) a random number.

14. ) The system of claim 12 wherein at least a portion of the unblocked data are associated with a BLUETOOTH device address.

15. ) The system of claim 12 wherein the frequency hopping sequence is determined using a BLUETOOTH device address.

16. ) The system of claim 12 wherein at least a portion of the unblocked data are associated with:

i) a PIN code, ii) a random number and iii) parity bits.

17. ) The system of claim 12 wherein at least a portion of the blocked data not associated with determining a frequency hopping sequence is quarantined.

18. ) The system of claim 12 wherein at least a portion of the unblocked data enables determination of one of:

a channel access code, a device access code, a clock parameter a device class, a page scan mode, and a BLUETOOTH device name.

19. ) The system of claim 12 wherein the initial link key is used in a challenge-response authentication process.

20. ) The system of claim 12 wherein blocking at least a portion of the data further comprises one of suppressing, discarding, quarantining, and masking the data.
