NB-IoT is a widely used technology for wide-area applications that is providing real-time information to system operators. However, either intentional or unintentional transient faults can potentially result in inappropriate control actions, jeopardizing the security, resilience, and reliability of NB-IoT network. PSD fault injection method drops power supply voltage of NB-IoT transmitter chip for different durations and voltage levels. To connect circuit of fault injection to NB-IoT network, a host computer is programmed as a fault injection manager. In this configuration, sending packets is done through one of NB-IoT chips, and receiving them is done on server side. The results of empirical fault injections showed that the fault tolerance of NB-IoT technology needs crucial improvement. To address this issue, an active retransmission technique (ART) method is proposed. ART involves leveraging time redundancy and retransmission of particular number of packets depending on the acceptable level of reliability and performance overhead.

This article proposes a novel three-stage scheme for encrypting images to address high-complexity and low-efficiency issues. First, the Secure Hash Algorithm-256 (SHA-256) is used to initialize an Intertwining Logistic Map (ILM), ensuring plaintext sensitivity and resistance to known chosen-text attacks. In the next confusion phase, a concentric-layer pixel-shuffling pattern is introduced to enhance the randomness of the image data. This pattern divides image pixels into different circular layers, with the number of layers determined by half of the square image’s size. To achieve complete randomness, zigzag shuffling is then applied. Finally, a condition-based diffusion approach integrates chaotic sequences with the confused image. If the selected chaotic sequence value is odd, DNA-based diffusion is performed between the confused image and the DNA-encoded masked image generated by the chaotic sequence of ILM; otherwise, an exclusive OR (XOR) operation is applied between the confused image and a chaotic sequence of ILM. The results of the XOR and DNA operations are then combined to generate the cipher image. The average entropy is 7.9973, NPCR is 99.62%, UACI is 33.46%, and the correlation is close to 0. The key space exceeds <span><math><mrow><mn>1</mn><msup><mrow><mn>0</mn></mrow><mrow><mn>105</mn></mrow></msup></mrow></math></span>, suggesting strong security.

To answer window queries constrained by a road network, this paper proposes to learn an Error-bounded regression Hilbert Tree (EHT) to predict a sample’s storage position with a function of Hilbert curve. The learning consists of data ordering and model training. During the data ordering, every road network constrained sample is projected onto a position-time grid whose cells are traversed by a Hilbert curve. During the model training, history samples are divided into a series of equal-duration periods, and an EHT is constructed for every period to establish the mapping between every spatio-temporal sample and its storage position. The EHT safely covers every qualifying sample within the given error bound, thus achieving a full recall. Further, it models the distribution with as tight a strip as possible, thus reducing the disk scanning cost to the minimum during query processing. Extensive experiments on real and synthetic datasets demonstrate that the EHT reduces the index size by a factor between 1.46 and 43.4 while consuming much fewer disk IOs, or at most one or two more disk IOs, compared to the state-of-the-art learned indexes. In comparison with the delicate indexes, the EHT reduces the index size by a factor between 5.46 and 62.5 while consuming much fewer or roughly the same number of disk IOs.</div></div>","PeriodicalId":50630,"journal":{"name":"Computers & Electrical Engineering","volume":"124 ","pages":"Article 110394"},"PeriodicalIF":4.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143894900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
