Power-Based Key Hopping (PBKH) and Associated Hardware Implementation

Power-Based Key Hopping (PBKH) is a process of key hopping that is used to interchange the user key of a cipher. Power based key hopping is founded on the idea of dynamic frequency power-based hopping to change the user key. This is achieved through computing the power of a previous cipher packet and comparing it with a standard value. In this work, we discuss various key hopping methods and suggest a procedure of power based key hopping. Moreover, we provide a Field Programmable Gate Array (FPGA) hardware implementation of the proposed key hopping technique.
