Oblivious polynomial evaluation and oblivious neural learning [PDF]
Theoretical Computer Science, 2005 We study the problem of oblivious polynomial evaluation (OPE). There are two parties, Alice who has a polynomial P, and Bob who has an input x. The goal is for Bob to compute P(x) in such a way that Alice learns nothing about x and Bob learns only what ...

Generation and Distribution of Quantum Oblivious Keys for Secure Multiparty Computation
Applied Sciences (Switzerland), 2020 The oblivious transfer primitive is sufficient to implement secure multiparty computation. However, secure multiparty computation based on public-key cryptography is limited by the security and efficiency of the oblivious transfer implementation.

Quantum Universally Composable Oblivious Linear Evaluation [PDF]
QuantumOblivious linear evaluation is a generalization of oblivious transfer, whereby two distrustful parties obliviously compute a linear function, $f (x) = ax + b$, i.e., each one provides their inputs that remain unknown to the other, in order to compute the

Forming Sequences of Patterns With Luminous Robots
IEEE Access, 2020 The extensive studies on computing by a team of identical mobile robots operating in the plane in Look-Compute-Move cycles have been carried out mainly in the traditional OBLOT model, where the robots are silent (have no communication capabilities) and ...

Fixed-point oblivious quantum amplitude-amplification algorithm
Scientific Reports, 2022 The quantum amplitude amplification algorithms based on Grover’s rotation operator need to perform phase flips for both the initial state and the target state. When the initial state is oblivious, the phase flips will be intractable, and we need to adopt

A device-independent protocol for XOR oblivious transfer [PDF]
Quantum, 2022 Oblivious transfer is a cryptographic primitive where Alice has two bits and Bob wishes to learn some function of them. Ideally, Alice should not learn Bob's desired function choice and Bob should not learn any more than what is logically implied by the ...
