Motivated by the aforementioned challenges, we present a new Deep-Learning empowered Threat Hunting Framework named DLTHF to protect SD-IoT data and detect (binary and multi-vector) attack vectors. First, an automated unsupervised feature extraction module is designed that combines data perturbation-driven encoding and normalization-driven scaling with the proposed Long Short-Term Memory Contractive Sparse AutoEncoder (LSTMCSAE) method to filter and transform dataset values into the protected format. Second, using the encoded data, a novel Threat Detection System (TDS) using Multi-head Self-attention-based Bidirectional Recurrent Neural Networks (MhSaBiGRNN) is designed to detect cyber threats and their types. In particular, a unique TDS strategy is developed in which each time instances is analyzed and allocated a self-learned weight based on the degree of relevance.

However, various adversarial threats are inevitable throughout the lifecycle of data generation, transmission, and utilization, leading to serious security risks. Trust assessment of visual sensors is a prerequisite for securing UAVs, but the multidimensionality of the trust elements and the uncertainty of the evidence limit its practical application. To advance this research, we innovatively propose a trust management scheme based on multi-granularity evidence fusion within the framework of belief functions (BFs) theory to adaptively respond to both known and unknown threats. We first propose a direct trust assessment model for known threats, which constructs multidimensional coarse-grained trust elements (MCTEs) and integrates multiple lightweight sub-models for basic belief assignment (BBA) to meet the need for fast response. Then, to address the unknown threats, we introduce pre-trained models to build multidimensional fine-grained trust elements (MFTEs) to construct trust recommendation models for indirect trust assessment for visual sensors. In addition, to accurately characterize the trustworthiness of visual sensors, we also introduce a BBA-weighted fusion method to achieve more reasonable trust aggregation by weakening highly conflicting evidence sources. Finally, to validate the effectiveness of the proposed method, we conducted a comprehensive trust assessment and security experiment on UAV aerial images. The results indicate that the proposed method demonstrates excellent performance and is beneficial for enhancing UAV security in adversarial attack scenarios.</p></div>","PeriodicalId":51004,"journal":{"name":"Computers & Security","volume":"148 ","pages":"Article 104108"},"PeriodicalIF":4.8,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142240712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Successful backdoor attacks can have serious consequences, such as attackers using backdoor generation methods to bypass critical face recognition authentication systems. In this paper, we propose PBADT, a precise backdoor attack with dynamic trigger. Unlike existing work that uses static or random trigger masks, we design an interpretable trigger mask generation framework that places triggers at positions that have the most significant impact on the prediction results. Meanwhile, backdoor attacks are made more efficient by using forgettable events to improve the efficiency of backdoor attacks. The proposed backdoor method is extensively evaluated on three face recognition datasets, LFW, CelebA, and VGGFace, while further evaluated on two general image datasets, CIFAR-10 and GTSRB.

However, the software with persistent runtime characteristics (e.g., web service programs) cannot be effectively tested by current coverage-based greybox (CG) fuzzers, which strictly rely on the termination state of the target software to feed test cases synchronously and obtain code coverage. The present approach requires delicate analysis and modification of the target to eliminate its persistence, but leads to excessive non-essential restarts during testing, resulting in low throughput.</p><p>To improve the convenience and efficiency of CG fuzzing for persistent software, we propose augmenting persistence (AugPersist) as a complementary method. AugPersist introduces the concept of persistent basic block (PBB) to leverage the inherent code features of persistent software. PBB can be found automatically and quickly before fuzzing based on the execution flow graph (EFG). On this basis, we develop a low- delay synchronous communication so that after regular test cases are fed into the target, the fuzzer can derive code coverage without rebooting the target, thus significantly minimizing extraneous restarts. Additionally, by utilizing the self-adaptive forkserver, we can dynamically adjust the re-execution point of the target to the PBB position, which further minimizes losses when test cases trigger exceptions and cause necessary restarts.</p><p>To show the potential of augmenting persistence, we create two implementations, AFL-AugPersist and AFLNet-AugPersist, using AFL and AFLNet as baselines. We evaluate both with their respective baselines on different benchmarks.

Due to the open nature of the wireless channel, smart radio environment, dynamic network topology, and adversarial machine learning (ML), 6G will face various unprecedented security threats. Given stringent requirements on quality of service (QoS), security, and massive low-cost Internet of Thing (IoT) devices, physical layer security (PLS) by exploiting the random nature of the wireless channel and/or intrinsic hardware imperfection emerges as a complementary approach to secure wireless communications. Meanwhile, the rapid development of artificial intelligence (AI) promotes the development of intelligent PLS solutions and smart attacks. In this paper, we make a comprehensive overview of PLS for RIS-based 6G systems from both defensive and offensive perspectives. We first introduce the vision of the RIS-enabled 6G smart radio environment. Then, typical security risks and requirements on RIS-based 6G are analyzed. After that, the state-of-the-art techniques on PLS are presented. Subsequently, major academic works on the physical layer security solution oriented to RIS are systematically reviewed.

Currently, numerous multi-copy cloud storage auditing schemes have been proposed. However, most of them depend on public key infrastructure, identity-based cryptography, or certificateless cryptography. These schemes encounter challenges such as complicated certificate management, key escrow, or the necessity for a secure channel for distributing keys, respectively. Furthermore, most of them are not resilient to copy-summation attack. To address the above problems, we propose a certificate-based multi-copy cloud storage auditing scheme supporting data dynamics. We design a novel dynamic structure named Leaves Merkle hash tree (LMHT) to achieve multi-copy dynamic updates. Different from traditional Merkle hash trees, LMHT has significant advantages in data deletion. In addition, the proposed scheme can resist copy-summation attack, in which cloud cannot pass the verification if it only stores summation of all copies without storing data blocks’ all copies.
