Abstract
Validation information is communicated in a Bluetooth Low Energy (BLE) connected session. Validation data is generated using said validation information. An advertisement string is broadcast from the BLE device in a connectionless session along with said validation data.
Claims15
The method to authenticate a Bluetooth Low Energy (BLE) connectionless communication, said method comprising:
- providing a BLE device having a memory;
- creating a secure, connected communication session with said BLE device;
- communicating validation information in said connected session;
- storing said validation information in said memory;
- receiving, in a connectionless session, a BLE packet broadcast including an advertisement string and validation data;
- and
- authenticating the source of said broadcast using said validation data contained in said BLE packet said validation information.
4 more elements
A Bluetooth Low Energy (BLE) system comprising:
- a BLE radio transceiver;
- an electronic memory;
- a microprocessor to connect said BLE transceiver in a connected session, the microprocessor to receive validation information in said connected session and to store the validation information in said electronic memory, the microprocessor to further receive a BLE packet containing an advertising string and validation data in a subsequent connectionless session, and to authenticate said broadcasted advertising string by comparing said stored validation information and said received validation data contained in BLE packet.
A product including a non-transitory storage medium having stored thereon instructions that, when executed by a machine, result in:
- creating a secure, connected Bluetooth low energy (BLE) communication link;
- exchange validation information over said secure, connected communication link;
- storing said validation information in said computer readable medium;
- generating validation data using said validation information;
- broadcasting a BLE packet containing an advertisement string and validating data from a BLE device in a connectionless session;
- and
- Transmitting said validation data along with said advertisement string in a BLE Packet.
