Binary Tree Based Forward Secure Signature Scheme in the Random Oracle Model [PDF]
International Journal of Electronics and Telecommunications, 2021 In this paper we construct and consider a new group-based digital signature scheme with evolving secret key, which is built using a bilinear map. This map is an asymmetric pairing of Type 3, and although, for the reason of this paper, it is treated in a ...

Indifferentiable hash functions in the standard model
IET Information Security, 2021 Indifferentiability of iterated hash functions is seen as evidence that there are no structural flaws in the iteration structure of the algorithm. However, it is often overlooked that such considerations only hold in the random oracle model and do not ...

Tightly Secure PKE Combiner in the Quantum Random Oracle Model
Cryptography, 2022 The development of increasingly sophisticated quantum computers poses a long-term threat to current cryptographic infrastructure. This has spurred research into both quantum-resistant algorithms and how to safely transition real-world implementations and

Uselessness for an Oracle model with internal randomness [PDF]
Quantum Information and Computation, 2014 We consider a generalization of the standard oracle model in which the oracle acts on the target with a permutation selected according to internal random coins. We describe several problems that are impossible to solve classically but can be solved by a quantum algorithm using a single query; we show that such infinity-vs-one separations between ...

Using intelligence techniques to automate Oracle testing [PDF]
Al-Rafidain Journal of Computer Sciences and Mathematics, 2023 The software development life cycle includes software testing as a critical step. Oracle testing is necessary to determine if a particular test case detects an error because the purpose of testing is to ensure that the application adheres to its ...

Quantum Depth in the Random Oracle Model
Proceedings of the 55th Annual ACM Symposium on Theory of Computing, 2023 We give a comprehensive characterization of the computational power of shallow quantum circuits combined with classical computation. Specifically, for classes of search problems, we show that the following statements hold, relative to a random oracle: (a) $\mathsf{BPP}^{\mathsf{QNC}^{\mathsf{BPP}}} \neq \mathsf{BQP}$.

Quantum Random Oracle Model for Quantum Public-Key Encryption
IEEE Access, 2019 Random oracle model is a general security analysis tool for rigorous security proof and effective cryptographic protocol design. In the quantum world, the attempts of constructing a quantum random oracle (QRO) have been made, such as quantum-accessible ...

A New Identification Scheme based on Syndrome Decoding Problem with Provable Security against Quantum Adversaries [PDF]
Journal of Universal Computer Science, 2019 Recently, in order to guarantee security against quantum adversaries, several identification (ID) schemes based on computational problems which are supposed to be hard even for quantum computers have been proposed. However, their security are only proven
