Secured management of maneuver identifications (IDS)
Systems and techniques are described for securely managing maneuver identifications (IDs) for vehicle-based communications. For example, a method may include transmitting a message associated with a potential maneuver by the vehicle, determining a maneuver identification (ID) for the potential maneuver based on the message, and transmitting a first maneuver message (including the maneuver ID) for the potential maneuver. In another example, a method may include receiving a first maneuver message including a maneuver ID, determining that the first maneuver ID is a new maneuver ID, and determining, based on the first maneuver ID being a new maneuver ID, whether the first maneuver ID matches a second maneuver ID determined based on a previously-received message. In another example, a method may include receiving maneuver messages that include a same maneuver identification (ID) and one or more source IDs and determining whether the source ID(s) of the maneuver messages match.
1 . A method for wireless communications at a vehicle, the method comprising:
transmitting, at the vehicle, a message associated with a potential maneuver by the vehicle;
applying, at the vehicle, a hashing algorithm to the message to generate a hashed message;
including, at the vehicle, the hashed message in a field of a first maneuver message as a maneuver identification (ID) for the potential maneuver; and
transmitting, from the vehicle to at least one other vehicle, the first maneuver message including the hashed message as the maneuver ID for the potential maneuver.

5 . The method of claim 4 , wherein the second maneuver message is a maneuver sharing coordination message (MSCM).
6 . The method of claim 1 , wherein the first maneuver message is a maneuver sharing coordination message (MSCM) indicating a request to perform the potential maneuver.
7 . The method of claim 1 , wherein the vehicle is configured to communicate with the at least one other vehicle using a vehicle-to-everything (V2X) protocol.
8 . A method for wireless communications at a first vehicle, the method comprising:
receiving, at a first vehicle, a message from a second vehicle;
receiving, at the first vehicle after receiving the message, a first maneuver message from the second vehicle, the first maneuver message including a first maneuver identification (ID) generated based on application of a hashing algorithm to the message;
determining, at the first vehicle, that the first maneuver ID of the first maneuver message is a new maneuver ID; and
determining, at the first vehicle based on the first maneuver ID being a new maneuver ID, whether the first maneuver ID matches a second maneuver ID determined based on application of the hashing algorithm to the received message.
9 . The method of claim 8 , wherein determining whether the first maneuver ID matches the second maneuver ID includes:
applying the hashing algorithm to the received message to generate a hashed message, the second maneuver ID including the hashed message; and
comparing the second maneuver ID to the first maneuver ID.
10 . The method of claim 8 , further comprising:
determining, at the first vehicle, that the first maneuver ID is different from the second maneuver ID; and

14 . The method of claim 8 , wherein the first maneuver message is a maneuver sharing coordination message (MSCM) and the received message is a safety message.
15 . The method of claim 14 , wherein the safety message is a basic safety message (BSM).
16 . The method of claim 8 , wherein the first vehicle is configured to communicate using a vehicle-to-everything (V2X) protocol.
17 . An apparatus for wireless communications, comprising:
a memory; and
one or more processors coupled to the memory, the one or more processors configured to:
transmit a message associated with a potential maneuver by a vehicle;
apply, at the vehicle, a hashing algorithm to the message to generate a hashed message;
including the hashed message in a field of a first maneuver message as a maneuver identification (ID) for the potential maneuver; and
transmit, to at least one other vehicle, a first maneuver message including the hashed message as the maneuver ID for the potential maneuver.
18 . The apparatus of claim 17 , wherein the message is a safety message.
19 . The apparatus of claim 18 , wherein the safety message is a basic safety message (BSM).
20 . The apparatus of claim 17 , wherein the message is a second maneuver message indicating an intent to perform the potential maneuver.
21 . The apparatus of claim 20 , wherein the second maneuver message is a maneuver sharing coordination message (MSCM).
22 . The apparatus of claim 17 , wherein the first maneuver message is a maneuver sharing coordination message (MSCM) indicating a request to perform the potential maneuver.
23 . The apparatus of claim 17 , wherein the apparatus is part of the vehicle, the vehicle being configured to communicate with the at least one other vehicle using a vehicle-to-everything (V2X) protocol.
24 . An apparatus for wireless communications comprising:
a memory; and
one or more processors coupled to the memory, the one or more processors configured to:
receive a message from a vehicle;
receive a first maneuver message from the vehicle after receiving the message, the first maneuver message including a first maneuver identification (ID) generated based on application of a hashing algorithm to the message;
determine that the first maneuver ID of the first maneuver message is a new maneuver ID; and
determine, based on the first maneuver ID being a new maneuver ID, whether the first maneuver ID matches a second maneuver ID determined based on application of the hashing algorithm to the received message.
25 . The apparatus of claim 24 , wherein the one or more processors are configured to:
apply the hashing algorithm to the received message to generate a hashed message, the second maneuver ID including the hashed message; and
