Random oblivious transfer
Webb30 mars 2024 · Using quantum oblivious keys, proposed the Optimise Quantum Oblivious Transfer (O-QOT) protocol that generates quantum-based Oblivious Transfers (OT). In [ 31 ], authors provided an overview of quantum oblivious transfer by investigating several quantum security models to emphasize the advantages of quantum OT over classical … Webb1-out-of-n oblivious transfer protocol in JavaScript. Protocol. To create 1-out-of-N, we use log2(N) 1-out-of-2 oblivious transfers of random bits to create log2(N) random strings. Each secret is masked with one of these strings (by XOR) and the receiving party picks one after which the sender reveals all the masked secrets.

Webb17 feb. 2024 · To conclude, random acts of kindness can make a person’s day and make a much bigger impact than the effort put into them equates to. One way to look at it is that they are simply events or interactions that people carry out subconsciously to prevent an awkward or confrontational interaction from occurring.

Recent works based on the pseudorandom correlation generator (PCG) paradigm presented a new way to generate random COT correlations using only communication sublinear to the …
In cryptography, an oblivious transfer (OT) protocol is a type of protocol in which a sender transfers one of potentially many pieces of information to a receiver, but remains oblivious as to what piece (if any) has been transferred. The first form of oblivious transfer was introduced in 1981 by Michael O. Rabin. In … Visa mer In Rabin's oblivious transfer protocol, the sender generates an RSA public modulus N=pq where p and q are large prime numbers, and an exponent e relatively prime to λ(N) = (p − 1)(q − 1). The sender encrypts the … Visa mer k-n Oblivious transfer is a special case of generalized oblivious transfer, which was presented by Ishai and Kushilevitz. In that setting, the sender has a set U of n messages, and the transfer constraints are specified by a collection A of permissible subsets … Visa mer Protocols for oblivious transfer can be implemented with quantum systems. In contrast to other tasks in quantum cryptography, … Visa mer In a 1–2 oblivious transfer protocol, Alice the sender has two messages m0 and m1, and wants to ensure that the receiver only learns one. Bob, the … Visa mer A 1-out-of-n oblivious transfer protocol can be defined as a natural generalization of a 1-out-of-2 oblivious transfer protocol. Specifically, a sender has n messages, and the receiver has an … Visa mer In the early seventies Stephen Wiesner introduced a primitive called multiplexing in his seminal paper "Conjugate Coding", which was the starting point of quantum cryptography. Unfortunately it took more than ten years to be published. Even though this primitive … Visa mer • k-anonymity • Secure multi-party computation • Zero-knowledge proof Visa mer
Webb30 aug. 2024 · In this work we focus on the so-called one-out-of-two random oblivious transfer. This is a two-party primitive in which a sender (Alice) gets two uniformly random bits b 0, b 1 and a receiver (Bob) gets a uniformly random choice bit c and b c. Bob remains ignorant about b ¯ c. On the other hand, Alice cannot learn the choice bit c. crypto loyaltyhttp://lxbwk.njournal.sdu.edu.cn/CN/10.6040/j.issn.1671-9352.9.2024.009 crypto lutheranWebb18 mars 2024 · random oblivious transfer (ROT) – en metod för kvantkryptering som påstås vara omöjlig att knäcka ens med en kvantdator.
