Mission-critical networks show great potential in emergency response and/or recovery, health care, critical infrastructure monitoring, etc. Such mission-critical applications demand that security service be "Anywhere," "Anytime," and "Anyhow." However, it is challenging to design a key management scheme in current mission-critical networks to fulfill the required attributes of secure communications, such as data integrity, authentication, confidentiality, non-repudiation, and service availability. In this paper, the authors present a self-contained public key-management scheme, a Scalable Method Of Cryptographic Key management (SMOCK), which achieves almost zero communication overhead for authentication, and offers high service availability.
