As control modules in cars become intelligent and automated, electrical systems become more complex. Dozens or even hundreds of electronic control units (ECUs) are used in many cars. In this case, the information security problem of the car is also latent in the dark. When the actual application load ratio of the CAN bus exceeds more than 30%, the delay of data communication and the probability of error frames multiply, causing serious communication congestion. A malicious intruder only needs to affect the bus data traffic to cause the collapse of the CAN bus network, which in turn changes the behavior of the car and has irreversible consequences. In order to enable the CAN bus to maintain its advantages, it can adapt to the new needs of contemporary in-vehicle networks with higher performance and more reliable security protection. In the paper, we propose a flow monitoring alarm module built into the in-vehicle CAN. This module embeds a statistical algorithm based on information theory. The algorithm has a small amount of computation and clear logic, which meets the lightweight requirements of embedded algorithms. Through multiple experiments, the module can monitor all Dos for in-vehicle CAN, as well as other traffic abnormalities with a monitoring alarm rate of more than 98%. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

As an extended version of frequent itemset patterns, periodic itemset patterns concern both the frequency and periodicity of itemsets at the same time, so they contain more information than frequent itemset patterns, which only concern the frequency. With further research, we found that, in some cases, the periodic itemset patterns with higher frequency, or with optimal periodicity, or with both higher frequency and optimal periodicity have higher application value. However, there is currently no work focusing on such a kind of periodic itemset patterns. In view of this, this paper first proposes a new concept of skyline periodic itemset patterns, and states the problem of skyline periodic itemset pattern mining, then presents an algorithm called SLPIM (SkyLine Periodic Itemset pattern Miner) for skyline periodic itemset pattern mining. SLPIM first adopts the well-known FP-Growth algorithm to mine all frequent itemset patterns, and then uses an effective judgment strategy to determine which frequent itemset patterns are skyline periodic itemset patterns. Finally, experiments are conducted on two real-world and two simulated datasets. The results show that SLPIM is competent for mining skyline periodic itemset patterns. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2023.

This paper describes a sub-object retrieval system based on a segmentation method. We also use dynamic partial function (DPF) and indexing by locality sensitive hashing (LSH) for improving system performance. Such a system is useful for finding a sub-object from a large image database. In order to obtain the sub-object from a sample image, we use a segmentation method to cut out the object. The system utilizes the segmentation results to capture the higher-level concept of images and gets a stable and accurate result. Experimental and comparison results, which are performed using a general purpose database containing 20,000 images, are encouraging

In this paper, we introduce two concepts of service semantic relation and semantic relation chain to figure out service composition relation and sequentially service composition. For parallel service composition, we propose web service community (WSC) model which corresponding to a Split+Join structure, So we introduce a kind of divide and conquer method to convert parallel service composition into sequentially service composition based on WSC chains and which can solve sequential and parallel service composition problems in an agreement way. Finally, a parallel composition example illustrations the execution process of our method. © 2009 IEEE.

Topological relations between spatial objects have played important roles in spatial representing and reasoning. Various models for expressing topological relations have been put forward. The Region Connection Calculus (RCC) and 9-Intersection Method (9IM) are most well-known topological formalisms, but neither of them can characterize the characteristic of topological relations between convex regions. In this paper, we introduce a new model for representing topological relations between two convex plane regions, which characterized with the topological properties of details of region A and B. Applying our model to triangles, we obtain a complete classification of topological relations which called RCC32. By calculating the cost of transforming one relation into another, the closest topological relation graph of RCC32 is given. © 2011 IEEE.

Internet key Exchange (IKE) can be used in vehicular communications in vehicular ad hoc networks (VANETs), but it requires a stable communication procedure, which is usually difficult to achieve because of the highly dynamic context of a VANET. In this paper, we propose a new method named social-network-based-privacy-preserving broadcast (SNB-PPB) for secure vehicular communications, which can omit the key exchange procedure. It transfers the information of online social networks to offline vehicular communications, dividing messages into different privacy levels and vehicles into different trust levels based on trust relations on social networks. The sender uses attributes on social networks and the message’s privacy level to encrypt messages;only those receivers who satisfy the corresponding trust level can decrypt the broadcast *** the best of our knowledge, this is the first time that social networks have been applied in VANETs to achieve secure vehicular communications and privacy preservation. Our simulation results show that our method enables the sender to decide the amount and percentage of vehicles that can decrypt the received broadcast.

This paper presents a Chinese topic crawler focused on customer development, in order to meet the needs of users for more accurate and particular Internet information. The concept of meta-search engine is introduced, and the keywords are expanded by the ontology of HowNet. Through the web crawler, preprocessing and classification, the information on customer relations can be divided into three categories: company, platform and meaningless. Numerical experiments show that satisfactory results can be obtained in some particular information-seeking areas. The average accuracy for classification is more than 80%, which can meet customer needs in most cases.

Coordination models can be classified into several classes, such as data-driven vs. control-driven coordination models, dependent vs. emergent coordination models, and hybrid coordination models. All these classifications are based upon implementation details. However, interaction is the kernel aspect of coordination, and coordination is the outcome of interactions between agents, so here, we give another kind of taxonomy based on interaction types, which are coordination models based on direct interactions and indirect interactions. Using this taxonomy, all coordination models are classified into two classes with no intersection, in addition, coordination models with indirect interactions and emergent behaviors are the direction of future work.

In Containing Order Rough Set Methodology (CORS), ordered attribute 'criterion' is introduced. Criterion is related semantically with decision attributes, which results in producing more rational and significant rules utilizing dominance relations. In this paper, some terminologies and properties on rules or rules set, such as robust, minimal, complete are discussed, the state of art in algorithms on rules generation are analyzed, and algorithms GRs and IGRs are proposed. We compare these two algorithms by experiments in time complexity, rules count and accuracy. We find that GRs can generate all minimal rules, but time complexity is high and IGRs' efficiency is better, but quality of rules are inferior to that of GRs. We also discuss the completeness of rules set and present a viewpoint that there are three hierarchies for completeness. In accuracy calculation, three formulas for accuracy calculation and two approaches for experimental test are given. © 2006 IEEE.

The existing 3D direction models approximate spatial objects either as a point or as a minimal bounding block, which decrease the descriptive capability and precision. Considering the influence of object's shape, this paper extends the planar cardinal direction (CD) into 3D space and obtains a new model called TCD (three-dimensional cardinal direction). Base on the smallest cubic TCD relations and original relations, explain the correlations between basic TCD relations and block algebra. Then according to the results in block algebra, two novel ways to compute the inverse and composition of basic TCD relations are proposed. And an O(n4) algorithm to check the consistency of a set of basic TCD constraints over simple blocks is given. © Springer-Verlag Berlin Heidelberg 2007.
