Provably sender-deniable encryption scheme [PDF]
Computer Science Journal of Moldova, 2015 The use of the well known provably secure public-key cryptoscheme by Rabin is extended for the case of the deniable encryption. In the proposed new sender-deniable encryption scheme the cryptogram is computed as coefficients of quadratic congruence, the

High-Security Multi-Slot Chaos Encryption With Dynamic Probability for 16-CAP PON
IEEE Photonics Journal, 2020 In this paper, a high-security chaos encryption with dynamic probability for 16-carrier-less amplitude/phase (CAP) PON is proposed by using two-layer chaos map with feedforward neural network-based XOR operator (FNNXOR).

2-bit, chained, probabilistic encryption scheme
Electronics Letters, 1989 In this letter we present a new probabilistic encryption algorithm based on the scheme proposed by Jingmin and Kaicheng in 1988. This algorithm utilises the public key concept and recursively encrypts two bits at a time. The message bit expansion is very low and is the same as in their scheme. At the same time, this new scheme is twice as fast.

Relating two standard notions of secrecy [PDF]
Logical Methods in Computer Science, 2007 Two styles of definitions are usually considered to express that a security protocol preserves the confidentiality of a data s. Reachability-based secrecy means that s should never be disclosed while equivalence-based secrecy states that two executions ...

FEBS Letters, EarlyView.Cells must clear mislocalized or faulty proteins from membranes to survive. The AAA+ ATPase Msp1 performs this task, but dissecting how its six subunits work together is challenging. We engineered linked dimers with varied numbers of functional subunits to reveal how Msp1 subunits cooperate and use energy to extract proteins from the lipid bilayer ...
