Medical internet of things device discovery
Devices and methods for internet of things (IOT) discovery/auto discovery are described. A discovery packet is received from a device. The discovery packet includes a first stream identifier and a request to establish a second stream. A stream acceptance packet is sent to the device. The stream acceptance packet includes the first stream identifier and an input for generating a second stream identifier. A first association is added to the registration based on the request to establish the second stream. The first association is between the second stream identifier and a determined destination. A first data packet is received from the device, where the first data packet includes/utilizes the second stream identifier. The first data packet is sent to the destination based on the first association in the registration.
1. A method for internet of things (IOT) discovery:
receiving a discovery packet from a device, wherein the discovery packet comprises a first stream identifier and a request to establish a second stream;
identifying a registration associated with the device in a routing table, wherein the registration is identified based on the first stream identifier;
determining a destination for the second stream based on the request to establish the second stream;
sending a stream acceptance packet to the device, wherein the stream acceptance packet comprises the first stream identifier and an input for generating a second stream identifier;
adding a first association to the registration based on the request to establish the second stream, wherein the first association is between the second stream identifier and the destination;
receiving a first data packet from the device, wherein the first data packet comprises the second stream identifier; and
sending the first data packet to the destination based on the first association in the registration.
2. The method of claim 1 , further comprising:
determining whether the registration exists in the routing table.
3. The method of claim 2 , further comprising:
disregarding the discovery packet when the registration is absent from the routing table.
4. The method of claim 2 , further comprising:
processing the discovery request when the registration exists in the routing table; and
accepting the request to establish the second stream when the registration exists in the routing table.
5. The method of claim 1 , wherein the input initiates a key establishment procedure with the device.
6. The method of claim 5 , wherein the key establishment procedure is a Diffie-Hellman key exchange.
7. The method of claim 5 , wherein at least a portion of the second stream identifier is a secure key established via the key establishment procedure.
8. The method of claim 7 , wherein the first data packet is cryptographically secured based on the second stream identifier.
9. The method of claim 1 , wherein the first stream identifier is associated with a device identifier.
10. The method of claim 9 , wherein the device identifier is a globally unique identifier (GUID).
11. A device for internet of things (IOT) discovery, comprising:
a processor;
memory in electronic communication with the processor, wherein the instructions are executable by the processor to:
receive a discovery packet from a device, wherein the discovery packet comprises a first stream identifier and a request to establish a second stream;
identify a registration associated with the device in a routing table, wherein the registration is identified based on the first stream identifier;
determine a destination for the second stream based on the request to establish the second stream;
send a stream acceptance packet to the device, wherein the stream acceptance packet comprises the first stream identifier and an input for generating a second stream identifier;
add a first association to the registration based on the request to establish the second stream, wherein the first association is between the second stream identifier and the destination;
receive a first data packet from the device, wherein the first data packet comprises the second stream identifier; and
send the first data packet to the destination based on the first association in the registration.
12. The device of claim 11 , wherein the instructions are further executable by the processor to determine whether the registration exists in the routing table.
13. The device of claim 12 , wherein the instructions are further executable by the processor to disregard the discovery packet when the registration is absent from the routing table.
14. The device of claim 12 , wherein the instructions are further executable by the processor to:
process the discovery request when the registration exists in the routing table; and
accept the request to establish the second stream when the registration exists in the routing table.
15. The device of claim 11 , wherein the input initiates a key establishment procedure with the destination.
16. The device of claim 15 , wherein the key establishment procedure is a Diffie-Hellman key exchange.
17. The device of claim 15 , wherein at least a portion of the second stream identifier is a secure key established via the key establishment procedure.
18. The device of claim 17 , wherein the first data packet is cryptographically secured based on the second stream identifier.
19. The device of claim 11 , wherein the first stream identifier is associated with a device identifier.
20. The device of claim 19 , wherein the device identifier is a globally unique identifier (GUID).
