Public Key Cryptography by Centralized Offline Server in Mission-Critical Networks
Mission-Critical networks show great potential in assisted living system, automotive networks, emergency rescue and disaster recovery system, military applications, critical infrastructure monitoring system. To build a secure communication system in that network, usually the first attempt is to employ cryptographic keys. Cryptographic key management is challenging due to the things like unreliable communications, limited bandwidth, network dynamics, large scale, resource constraints in wireless ad-hoc communications. Public-Private key pair in Mission-Critical networks to fulfill the required attributes of secure communications, such as data integrity, authentication, confidentiality, non-repudiation and service availability.
