A basic procedure for transforming readable data into encoded forms is encryption, which ensures security when the right decryption keys are used. Hadoop is susceptible to possible cyber-attacks because it lacks built-in security measures, even though it can effectively handle and store enormous datasets using the Hadoop Distributed File System (HDFS). The increasing number of data breaches emphasizes how urgently creative encryption techniques are needed in cloud-based big data settings. This paper presents Adaptive Attribute-Based Honey Encryption (AABHE), a state-of-the-art technique that combines honey encryption with Ciphertext-Policy Attribute-Based Encryption (CP-ABE) to provide improved data security. Even if intercepted, AABHE makes sure that sensitive data cannot be accessed by unauthorized parties. With a focus on protecting huge files in HDFS, the suggested approach achieves 98% security robustness and 95% encryption efficiency, outperforming other encryption methods including Ciphertext-Policy Attribute-Based Encryption (CP-ABE), Key-Policy Attribute-Based Encryption (KB-ABE), and Advanced Encryption Standard combined with Attribute-Based Encryption (AES+ABE). By fixing Hadoop’s security flaws, AABHE fortifies its protections against data breaches and enhances Hadoop’s dependability as a platform for processing and storing massive amounts of data.

RADAR and communications are vulnerable as noise and interference contaminate the received signals and produce errors limiting their resolution, their accuracy and speed. To answer the growing needs for more reliable and accurate microwave intelligence in an ever more complex electromagnetic environment, there is a growing need to develop innovative microwave sensors with greater signal sensitivity, selectivity and integrity. © 2024 IEEE.

The development of quantum computers, which could potentially implement Shor's algorithm and thereby pose a threat to classical encryption, has created the need for establishing ultra-secure communication systems. One solution is quantum key distribution (QKD), a method based on the principles of quantum mechanics that enables sharing an encryption key in a way that is fundamentally resilient to computational attacks, quantum or classical. QKD used together with a one-time-pad symmetric cryptography algorithm thus provides information-theoretically secure communication. In addition, QKD enables the detection of any eavesdropping attempt on communications lines. While classical optical communication systems allow signal amplification, the no-cloning theorem from the foundations of quantum mechanics prohibits the cloning of unknown states. This nogo theorem results in the practical limitation of quantum key distribution via optical fibers, prompting the need for free-space solutions. In this work, we present the proposed design of the first Optical Ground Station connected to the terrestrial Croatian quantum Communication Infrastructure through a QKD node. The station's function involves receiving prepare-and-measure photons from the low Earth orbit satellite and quantum key generation through the decoy-state BB84 protocol. By utilizing the satellite as a trusted node, this process ensures ultra-secure communication between two optical ground stations. © 2024 IEEE.

Implementation of a continuous-time quantum walk on a sparse graph

Continuous-time quantum walks (CTQWs) play a crucial role in quantum computing, especially for designing quantum algorithms. However, how to efficiently implement CTQWs is a challenging issue. In this paper, we study the implementation of CTQWs on sparse graphs, i.e., constructing efficient quantum circuits for implementing the unitary operator e−iHt, where H=γA (γ is a constant and A corresponds to the adjacency matrix of a graph). Our result is, for a d-sparse graph with N vertices and evolution time t, we can approximate e−iHt by a quantum circuit with gate complexity (d3∥H∥tNlog2(N))1+o(1), compared to the general Pauli decomposition, which scales like (∥H∥tN4log2(N))1+o(1). For sparse graphs, for instance, d=O(1), we obtain a noticeable improvement. Interestingly, our technique is related to graph decomposition. More specifically, we decompose the graph into a union of star graphs, and correspondingly, the Hamiltonian H can be represented as the sum of some Hamiltonians Hj, where each e−iHjt is a CTQW on a star graph which can be implemented efficiently.
