Quantum cryptography、consisting of quantum key distribution (QKD) and one-time pad encryption, allows for communication with unconditional security. In QKD systems, the senders encode information on single photons one by one, while the receivers measure the photon states and decode the information. By distilling possible eavesdropped bits, secure keys can beContinue Reading

Application architects need to make informed choices to use cryptography well: + Alternative key architectures have their merits and drawbacks. PKIs, in particular, should be contrasted with symmetric key architectures such as Kerberos. + Network protocol characteristics are pivotal in ensuring distributed applications meet security requirements. Key strength choices impactContinue Reading
