Each device is given its Device Keys and a 31-bit number d called the device number. For each Device Key, there is an associated number denoted the path number, the “u” bit mask, and the “v” bit mask. The path number denotes the position in the tree associated with the Device Key. This path number defines a path from the root to that ...
A quantum cryptographic protocol is device-independent if its security does not rely on trusting that the quantum devices used are truthful. Thus the security analysis of such a protocol needs to consider scenarios of imperfect or even malicious devices. Several important problems have been shown to admit unconditional secure and device ...
Over-the-air rekeying (OTAR) refers to transmitting or updating encryption keys (rekeying) in secure information systems by conveying the keys via encrypted electronic communication channels ("over the air"). [1] It is also referred to as over-the-air transfer (OTAT), or over-the-air distribution (OTAD), [2] depending on the specific type, use ...
A Key Selection Vector (KSV) is a numerical identifier associated with a Device Key Set which is distributed by a Licensor or its designee to Adopters and is used to support authentication of Licensed Products and Revocation as part of the HDCP copy protection system. The KSV is used to generate confidential keys, specifically used in the ...
AN/PYQ-10. The AN /PYQ-10 Simple Key Loader (SKL) is a ruggedized, portable, hand-held fill device, for securely receiving, storing, and transferring data between compatible cryptographic and communications equipment. The SKL was designed and built by Ralph Osterhout [citation needed] and then sold to Sierra Nevada Corporation, with software ...
A KYK-13 fill device. A fill device or key loader is a module used to load cryptographic keys into electronic encryption machines. Fill devices are usually hand held and electronic ones are battery operated. Older mechanical encryption systems, such as rotor machines, were keyed by setting the positions of wheels and plugs from a printed keying ...
Post-quantum cryptography (PQC), sometimes referred to as quantum-proof, quantum-safe, or quantum-resistant, is the development of cryptographic algorithms (usually public-key algorithms) that are currently thought to be secure against a cryptanalytic attack by a quantum computer. Most widely-used public-key algorithms rely on the difficulty of ...
