Abstract
QKD is a technique for sharing a secret key between two parties by utilizing quantum mechanics. Two well-known protocols that contributed to securing the communication are BB84 and E91. This chapter discussed the principle of quantum security and cryptography and emphasizes the recent developments and potential applications of new and emerging applications of these techniques in security in current applications or the future; moreover, different scenarios for using QKD lengths such as seeds for generating keys to encryptions messages, using QKD as key for DES or AES algorithms, also, using QKD in real-life scenarios such as healthcare in personal area networks for protecting the privacy of the patients' data, or railway monitoring scenarios to encrypt the collected data generated by the sensors are discussed.
