Research and Design of Improved HIPL Cookie Mechanism

Based on investigaing of Host Identity protocol implementation HIPL,Improved mechanism IHC is proposed to solve the problems of HIPL which include extra calculate and storage cost,linear Puzzle pseudo-random function and HIPL difficulty coefficient for not taking responder's resource consumption into consideration.By reducing the storage of responder's data and state information and using resource-balance mechanism,responder can adjust the Cookie mechanism on non-optimal QoS conditions.Moreover,the IHC mechanism is implemented and tested on Linux.The test results indicate IHC mechanism can protect responder's system resources effectively and improve system performance to avoid system service termination or collapse.
