Group theory, specifically the combinatorial group theory of finitely presented groups,has been utilized effectively in cryptology. Several new public key cryptosystems have been developed and this has ushered a new area in cryptography called group based cryptography. Braid groups have been suggested as possible platforms and this has led to what is called braid group cryptography. This has also had a profound effect on theoretical group theory as techniques have been found to analyse these group-based cryptosystems.The basic idea is that a finitely presented group can be described by a finite amount of data.This provides techniques to enormously compress and hide information. This suggests that we have only barely scraped the surface of using finitely presented groups for data control, security and storage. For example, we describe a far-reaching extension for controlling access to files which could be relevant in medical records.

The QC-MDPC code-based KEM BIKE is one of the Round-3 candidates of the NIST PQC standardization project. Its Round-2 specification document described variants claiming to have IND-CCA security. The security proof used the Fujisaki–Okamoto transformation and a decoder targeting a Decoding Failure Rate (DFR) of (for Level-1 security). However, several aspects needed to be amended in order for the IND-CCA proof to hold. The main issue is that using a decoder with DFR of does not necessarily imply that the underlying PKE is δ-correct with , as required. In this paper, we handle the necessary aspects to ensure the security claim is correct. In particular, we close the gap in the proof by defining the notion of message-agnostic PKE. We show that the PKEs underlying the BIKE versions are message-agnostic. This implies that BIKE with a decoder that has a sufficiently low DFR is also an IND-CCA KEM.

In this paper we study a strategy for adapting the “Tiny Claw” Grover-based attack of Biasse and Pring (A framework for reducing the overhead of the quantum oracle for use with Grover's algorithm with applications to cryptanalysis of SIKE, J. Math. Cryptol. 15 (2019), pp. 143–156) for attacking SIKE and abstract it under a realistic model of classical memory-access costs. Our results allow us to retain the almost quadratic reduction in the overheads involved with the implementing the quantum oracle in this cost model and demonstrate how the cost of the parallel version of this attack scales in a manner superior to that of a naive use of Grover’s algorithm. In order to investigate the utility of the Tiny Claw approach, we perform a quantum resource estimation of the classical and quantum resources required to attack various SIKE instances with Tiny Claw when when we are limited to hardware, finding interesting price-points.
在本文中，我们研究了一种策略，以适应Biasse和Pring基于Grover的“Tiny Claw”攻击(一种用于减少与Grover算法一起使用的量子预言器开销的框架，用于SIKE, J. Math的密码分析)。Cryptol. 15 (2019)， pp. 143-156)攻击SIKE，并将其抽象在经典内存访问成本的现实模型下。我们的结果使我们能够保留在这个成本模型中实现量子预言器所涉及的开销的几乎二次减少，并演示了这种攻击的并行版本的成本如何以优于单纯使用Grover算法的方式进行扩展。为了研究Tiny Claw方法的效用，当我们限于硬件时，我们对使用Tiny Claw攻击各种SIKE实例所需的经典和量子资源进行了量子资源估计，找到了有趣的价格点。

ABSTRACT Attribute-Based Authenticated Key Exchange (ABAKE) protocols allow two or more users to establish a shared key and achieve mutual authentication over an insecure network, while providing fine-grained access control over transmitted data. The existing ABAKE protocols are very inefficient, requiring a large number (polynomial in the size of the access policies) of pairing and exponentiation operations. This presents a major hindrance in the real-world deployment of these protocols. In this work, we present a construction of ABAKE protocol where the number of pairing operations is constant (to be precise only 7) and the number of exponentiation operations is linear to the number of clauses in the disjunctive normal form representing the general access policies. To this end, we construct an Attribute-Based Signcryption (ABSC) scheme with constant number of pairings, and use it as the main building block in our ABAKE construction. This also gives the first construction of ABSC schemes with constant number of pairings for general purpose access policies in the standard model. Another important and desirable feature of our ABAKE construction is that it is round-optimal, i.e. it is a single round protocol. We analyse the security of our ABAKE construction in the Attribute-Based extended Canetti-Krawzyck (ABeCK) model, and prove its security assuming the hardness of a variant of the Bilinear Diffie-Hellman Exponent problem in the random oracle model.

ABSTRACT DP-colouring (also known as correspondence colouring), introduced by Dvořák and Postle, is a generalization of list colouring. Many results on list-colouring of graphs, especially of planar graphs, have been extended to the setting of DP-colouring. Recently, Pongpat and Kittikorn [P. Sittitrai and K. Nakprasit, Suffficient conditions on planar graphs to have a relaxed DP-3-colourability, Graphs and Combinatorics 35 (2019), pp. 837–845.] introduced DP- -colouring to generalize -colouring and -choosability. They proved that every planar graph G without -cycles is DP- -colourable. In this note, we show the following results:(1) Every planar graph G without -cycles is DP- -colourable; (2) Every planar graph G without -cycles is DP- -colourable; (3) Every planar graph G without -cycles is DP- -colourable.

In this paper, we obtain the induced -packing k-partition number for trees, slim trees, split graphs, complete bipartite graphs, grids and circulant graphs. We also deal with networks having perfect -packing where is a claw on four vertices. We prove that an induced -packing k-partition problem is NP-Complete. Further we prove that the induced -packing k-partition number of is 2 for all hypercube networks with perfect -packing and prove that for all locally twisted cubes with perfect -packing.

One of cloud computing’s fundamental problems is the balancing of loads, which is essential for evenly distributing the workload across all nodes. This study proposes a new load balancing algorithm, which combines maximum-minimum and round-robin (MMRR) algorithm so that tasks with long execution time are allocated using maximum-minimum and tasks with lowest execution task will be assigned using round-robin. Cloud analyst tool was used to introduce the new load balancing techniques, and a comparative analysis with the existing algorithm was conducted to optimize cloud services to clients. The study findings indicate that ’MMRR has brought significant changes to cloud services. MMRR performed better from the algorithms tested based on the whole response time and cost-effectiveness (89%). The study suggested that MMRR should be implemented for enhancing user satisfaction in the cloud service.
