Abstract
A method for authentication and related devices includes obtaining a first session key BS1 generated according to a set X and a set Y. The set X is a set of samples of received signal strength indicators (RSSIs) of a wireless channel of a user equipment (UE), and the set Y is a set of samples of RSSIs of a wireless channel of a vehicle. Upon receiving a second message from the UE, wherein the second message is hashed by a second session key BS2, extracting the second session key BS2 from the second message. When the first session key BS1 is the same as the second session key BS2, the authentication between the UE and the vehicle is successful.
Claims20
An apparatus, comprising:
- a memory configured to store programming instructions;
- and
- one or more processors coupled to the memory and configured to execute the instructions to cause the apparatus to:
- obtain a first session key BS1, wherein the first session key BS1 is based on LC from a server, wherein Lc is a list of common indexes combining LX_disc and LY_disc, wherein LX_disc is a list of indexes discarded during quantization of a set X, wherein LY_disc is a list of indexes discarded during quantization of a set Y, wherein X is a set of samples of first received signal strength indicators (RSSIs) of a wireless channel of a user equipment (UE), and wherein Y is a set of samples of second RSSIs of a wireless channel of a vehicle;
- receive a first message from the UE, wherein the first message is hashed by a second session key BS2, and wherein the second session key BS2 is based on Lc;
- extract BS2 from the first message;
- and
- authenticate a session between the UE and the vehicle when the first session key BS1 is the same as the second session key BS2.
A method comprising:
- obtaining a first session key BS1, wherein the first session key BS1 is based on Lc from a server, wherein Lc is a list of common indexes combining LX_disc and LY_disc, wherein LX_disc is a list of indexes discarded during quantization of a set X, wherein LY_disc is a list of indexes discarded during quantization of a set Y, wherein X is a set of samples of first received signal strength indicators (RSSIs) of a wireless channel of a user equipment (UE), and wherein Y is a set of samples of second RSSIs of a wireless channel of a vehicle;
- receiving a first message from the UE, wherein the first message is hashed by a second session key BS2, and wherein the second session key BS2 is based on Lc;
- extracting BS2 from the first message;
- and
- authenticating a session between the UE and the vehicle when the first session key BS1 is the same as the second session key BS2.
A computer program product stored in a non-transitory computer readable medium and comprising a computer program that, when executed by one or more processors, causes an electronic device to:
- obtain a first session key BS1, wherein the first session key BS1 is based on Lc from a server, wherein Lc is a list of common indexes combining LX_disc and LY_disc, wherein LX_disc is a list of indexes discarded during quantization of a set X, wherein LY_disc is a list of indexes discarded during quantization of a set Y, wherein X is a set of samples of first received signal strength indicators (RSSIs) of a wireless channel of a user equipment (UE), and wherein Y is a set of samples of second RSSIs of a wireless channel of a vehicle;
- receive a first message from the UE, wherein the first message is hashed by a second session key BS2, and wherein the second session key BS2 is based on Lc;
- extract BS2 from the first message;
- and
- authenticate a session between the UE and the vehicle when the first session key BS1 is the same as the second session key BS2.
