摘要：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. So we go for an Self-Contained Public Key management scheme called Scalable method of cryptographic key management(SMOCK),which achieves almost Zero communication overhead for authentication and offers high service availability and also allows a mobile node to contain all of the necessary information for authentication locally. SMOCK provides a small number of cryptographic keys are stored offline at individual nodes before they are deployed in the network. The scheme allows a combinatorial design of Public-Private key pairs, to use good scalability in terms of the number of nodes and storage space. That means nodes combine more than one key pair to encrypt and decrypt messages.
