Abstract
This specification describes technologies relating to a multi-aspect identifier used in a network protocol handshake for establishing a network connection, while providing protection against denial of service attacks. For example, an employed cookie format can be enhanced to contain multiple parts so that cookies that would otherwise be valid if the source address matched can be distinguished from those that are entirely incorrect, and a message can be sent with a replacement cookie in such cases, without generating state at the responding node.
