The Proposed Scheme Utilizes Extended GYKI 52466 site Chaotic Maps The mechanism which is described within this paper has 3 phases, that are the parameter initialization phase, the registration phase, along with the key generation phase.

Registration Phase In this phase, the entity (e) registers its identity (ID) with the registration center (RC) and generates the corresponding private key (SK). This SK is then sent back via a safe channel for the entity (e), whose identity (ID) is published. Figure 2 schematically depicts the registration phase.
