Relativized obliviousness [PDF]

, 2005
Relativized obliviousness is introduced to capture the intuitive idea, that some problems allow fastest computations which are more oblivious than do other problems, without any of such computations being oblivious in the standard sense. It is shown that each increase in the obliviousness of an algorithm (in several different well-defined meanings ...

Physical implementation of oblivious transfer using optical correlated randomness

Scientific Reports, 2017
We demonstrate physical implementation of information-theoretic secure oblivious transfer based on bounded observability using optical correlated randomness in semiconductor lasers driven by common random light broadcast over optical fibers.

Oblivious evaluation of multivariate polynomials

Journal of Mathematical Cryptology, 2013
One of the fundamental problems of multi-party computation is Oblivious Polynomial Evaluation. In that problem, that was introduced by Naor and Pinkas, Alice has a polynomial and Bob has a point .

On the Composability of Statistically Secure Random Oblivious Transfer

Entropy, 2020
We show that random oblivious transfer protocols that are statistically secure according to a definition based on a list of information-theoretical properties are also statistically universally composable.

Exon: An Oblivious Exactly-Once Messaging Protocol With Reliable Delegation

IEEE Access
TCP is the default transport protocol of choice, namely for message-oriented middleware protocols (e.g., ZMTP, AMQP, MQTT) or distributed language runtimes (e.g., distributed Erlang), where exactly-once (EO) messaging is paramount.

Extending oblivious transfers efficiently [PDF]

, 2003
. We consider the problem of extending oblivious transfers: Given a small number of oblivious transfers “for free, ” can one implement a large number of oblivious transfers?

Error-tolerant oblivious transfer in the noisy-storage model

Physical Review Research, 2023
The noisy-storage model of quantum cryptography allows for information-theoretically secure two-party computation based on the assumption that a cheating user has at most access to an imperfect, noisy quantum memory, whereas the honest users do not need ...

Blocking Optimality in Distributed Real-Time Locking Protocols [PDF]

Leibniz Transactions on Embedded Systems, 2014
Lower and upper bounds on the maximum priority inversion blocking (pi-blocking) that is generally unavoidable in distributed multiprocessor real-time locking protocols (where resources may be accessed only from specific synchronization processors) are ...
