I have a continuous stream of real-time data. It must be consumed immediately or discarded, so I'm using UDP for transmission without ACK or retransmission (the connection is unreliable).
The packets I'm sending are of the same length, and one packet is sent per transmission (each next packet invalidates the previous one).
Is it insecure to use AES for encryption, reinitializing the AES context with the same key for each packet?
The AES key is pre-shared over a known wired secure channel.
