Communication Security and Key Safety



In this chapter, we present a brief review of traditional secure communication systems and their design principles. In order to allow these systems to function properly, users must keep some secrets, typically referred as the key. Once the key is obtained by the adversary, the users’ communication will no longer be secure. The safety of the key is a premise of communication security. However, key safety is difficult to guarantee in practice. There are numerous vulnerabilities that allow the adversary to obtain the key and then compromise communication security. The decisive role of key safety becomes an inherent weakness in many practical systems.
