Abstract

Methods and systems for processing Ethernet data are disclosed and may comprise receiving Ethernet data via a single gigabit Ethernet IP telephone chip. A secure application key may be received from a secure server by an OSM integrated within the gigabit Ethernet IP telephone chip for processing the received Ethernet data. The received Ethernet data may be processed by the gigabit Ethernet IP telephone chip based on the received secure application key. A unique security identifier internal to the single gigabit Ethernet IP telephone chip may be communicated off-chip to the secure server. The unique security identifier may identify the single gigabit Ethernet IP telephone chip. The secure server may authenticate the gigabit Ethernet IP telephone chip based on the unique security identifier internal to the single gigabit Ethernet IP telephone chip, prior to the receiving of the secure application key.
