Abstract
Key agreement is a process for two entities to agree on a shared secret key in a way that both entities contribute information to establish the shared key. Diffie-Hellman key agreement protocol is a seminal work in this problem area. Recently, because of the rising of identity-based cryptography, identity-based key agreement also becomes a hot research topic. An identity-based (ID-based) key agreement protocol is an key agreement protocol based on identity-based environments, that is, public keys are related to identities. However, most of existing ID-based key agreement protocols are based on single private key generator (PKG) environments. That is, only one entity is responsible to generate private keys for users. However, it is impractical that only one PKG exists in the whole world. The PKG becomes a single point of failure. Moreover, these environments are not scalable. If changing system parameters is required, it is infeasible to do so in single PKG environments. Because every entity in the world has to change its parameter accordingly. Therefore, it is natural that each administrative domain has its own PKG. A desirable feature of multiple PKG environments is to have multiple independent PKGs. That is, each PKG has its own unique system parameters, like a master key, groups, a pairing function, etc. Independent PKGs make each PKG has freedom to choose its own system parameters according to its need.
