Finally, MR receives the packet, decapsulates
it, and forwards it for the MNN .
The decryption algorithm takes as input a private key SK for Ikey and a cipher text CT associated with lene and decapsulates
cipher text CT to recover a session key.
Upon receiving the MAC frames, the UE reassembles and decapsulates
them as RTP packets through RLC/PDCP/IP/UDP layers.
Then, the MR decapsulates
the packet and forwards to the MH.
RP destination then receives encapsulated data packets, decapsulates
them and sends it over the shared tree.
Then the current foreign agent for this mobile node receives the packet and decapsulates
it and then transmits it to the node.
When the serving MR of the destination MC receives the packet, it decapsulates and if required forwards the packet to current MR through the forward chain.
On receiving, SSMR1 decapsulates the packet and forwards it to SCMR1 through forward chain.
Then the MR decapsulates and forwards the packets to the current MR of the MC.
After receiving the packets the CSMR decapsulates and delivers those to CMC.
The adversary is also given access to a flexible decapsulation oracle (FDO)  that decapsulates
a given encapsulation created for a receiver by a sender.
