Autonomous recognition of erroneous raw key bit bias in quantum key distribution [PDF]
Scientific ReportsAs quantum key distribution technologies mature, it is pertinent to consider these systems in contexts beyond lab settings, and how these systems may have to operate autonomously.

MOBS: Matrices Over Bit Strings Public Key Exchange [PDF]
La Matematica, 2021 We use matrices over bit strings as platforms for Diffie-Hellman-like public key exchange protocols. When multiplying matrices like that, we use Boolean OR operation on bit strings in place of addition and Boolean AND operation in place of multiplication.

Key Distillation and the Secret-Bit Fraction [PDF]
IEEE Transactions on Information Theory, 2008 We consider distillation of secret bits from partially secret noisy correlations P_ABE, shared between two honest parties and an eavesdropper. The most studied distillation scenario consists of joint operations on a large number of copies of the ...

Qubit and bit-based quantum hybrid secret key generation [PDF]
The European Physical Journal D, 2022 Abstract For the generation of a secret key, hardly a quantum algorithms integrating states and bits have yet developed. Integrating random states and bits is difficult for a combiner component. The underlying problems of the study are the design of a quantum circuit, an algorithm, state polarization setup, and the concatenation of bits and ...

Compressed Secret Key Agreement:Maximizing Multivariate Mutual Information per Bit [PDF]
Entropy, 2017 The multiterminal secret key agreement problem by public discussion is formulated with an additional source compression step where, prior to the public discussion phase, users independently compress their private sources to filter out strongly correlated

NEW KEY EXPANSION FUNCTION OF RIJNDAEL 128-BIT RESISTANCE TO THE RELATED-KEY ATTACKS
Journal of ICT, 2018 A master key of special length is manipulated based on the key schedule to create round sub-keys in most block ciphers. A strong key schedule is described as a cipher that will be more resistant to various forms of attacks, especially in related-key ...

Are 128 Bits Long Keys Possible in Watermarking? [PDF]
, 2012 The question raised in this poster is the following: is the key length of a watermarking system proportional to the key length of the seed used to generate the watermark? For example, if a watermark is generated from a binary sequence of size n, does it means that the key length is 2n?

Asynchronous-bit-rate differential phase-shift-keying [PDF]
APL PhotonicsAn adaptive differential-phase-shifting (DPS) quantum key distribution (QKD) protocol improved by encoding asynchronous-bit-rate with harmonic clock tunability, decoded by shortened delay-line interferometer (DLI) with enhancing stability, and received by single-photon detection with long hold-off is demonstrated to realize low-erroneous transmission ...

Proposing A Symmetric Key Bit-Level Block Cipher [PDF]
, 2016 A novel bit level block cipher based symmetric key cryptographic technique using G.C.D is proposed in this research paper. Entire plain text file is read one character at a time and according to the binary representation of ASCII value of the characters, entire plain text file is divided into n number of 16 bit blocks. Then an agreed-upon symmetric key

Continuous operation of high bit rate quantum key distribution [PDF]
, 2010 We demonstrate a quantum key distribution with a secure bit rate exceeding 1 Mbit/s over 50 km fiber averaged over a continuous 36-hours period. Continuous operation of high bit rates is achieved using feedback systems to control path length difference ...
