target = "https://www.rfc-editor.org/rfc/rfc9000#section-10.3.1" [[exception]] quote = ''' The endpoint identifies a received datagram as a Stateless Reset by comparing the last 16 bytes of the datagram with all stateless reset tokens associated with the remote address on which the datagram was received. ''' reason = ''' s2n-quic maintains a hash map of all Stateless Reset Tokens to the connection they are associated with. Since the hash map provides constant time lookups by using SipHash initialized with random state, it is not necessary to use remote address to reduce the potential pool of matching Stateless Reset Tokens before performing the comparison. In addition, validating the remote address matches the remote address associated with the Stateless Reset Token provides minimal additional security benefit given the ease of spoofing remote addresses and the difficult of forging a valid Stateless Reset Token.
