Abstract:
1. A method for establishing Security Association (SA) mechanism between a Mobile Node (MN) and a plurality of Point of Services (PoS) in a communication network, the method comprising: sending a first request including a primary PoS identity from a primary PoS to a secondary PoS, wherein the first request is at least one of a first registration request and a first authentication request; receiving a first response at the primary PoS along with a first key from the secondary PoS, wherein the first response is at least one of a first registration response and a first authentication response, wherein the first key is derived at the secondary PoS based on the primary PoS identity; receiving a second request including a MN identity from a Mobile Node at the primary PoS, for accessing the plurality of PoS, wherein the second request is at least one of a second registration request and a second authentication request; deriving, by the primary PoS, a second key based on the MN identity and the derived first key; sending a second response along with the second key from the primary PoS to the MN, wherein the second response is at least one of a second registration response and a second authentication response; sending the MN identity from the primary PoS to the secondary PoS; and establishing communication between the secondary PoS and the MN based on the second key received by the MN and the second key generated at the secondary PoS, wherein the second key is generated at the secondary PoS based on the MN identity and the primary PoS identity.
