Abstract
A system and method for secure communication for power over Ethernet (PoE) between a computing device and a switch. Various power management information can be used as inputs in a process for determining a power request/priority. This power management information can be communicated in Layer 2, Layer 3, or higher messaging during initial power allocation and ongoing power reallocation. Encryption of such messaging enables confidentiality, secure allocation processes, and prevention of denial of service attacks.
