In this paper, we presents a method to quantity the capabilities of the attacker and the defender under the t-out-of-n secret sharing scheme. More specifically, we present a new general notion of limitation to provide a precise bound of attack and defense capability under the $(t, n)$-threshold sharing scheme. Furthermore, we discuss the best selection of authorized shares t. Firstly, we transform the attack and defense under the $(t, n)$-threshold secret sharing scheme into the communication problem in information theory, and establish the attack channel and defense channel from the point of view of the attacker and the defender. Moreover, we describe the capability of both attacking and defending by introducing average mutual information, and analyze the limitation of the capability of both sides, as well as the maximum value of the average mutual information is the channel capacity. Finally, according to the average amount of mutual information of the change curve under different scenarios of secret sharing, we compare and analyze the influence of the capability limitation of the attacker and the defender on the value of t, and get the best selection of t.","PeriodicalId":414672,"journal":{"name":"2021 International Conference on Networking and Network Applications (NaNA)","volume":"30 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125881465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the complex mobility characteristics of vehicles and the diversified vehicular service requirements, the traditional cellular handover mechanism may not maintain high-quality network service for various connected vehicles. This paper concentrates on satisfying the network requirements of different vehicular services, keeping network load balance and avoiding unnecessary handover under the EPC-based LTE-5G RAN-level network architecture. We first develop the modified heterogeneous cellular network architecture with the assistance of the multi-access edge computing (MEC) technology, the MEC server works as a coordinator which is responsible for handover state information management and executing network selection algorithm to help vehicles access the most suitable candidate network. The network selection algorithm uses a quality of service (QoS) coverage conversion methods which calculate the QoS boundary of candidate networks to satisfy the specific service requirement and balance the network load. A long short-term memory (LSTM)-based trajectory prediction method is designed to obtain the sojourn time of a vehicle staying in the QoS boundary of candidate networks. The sojourn time acts as a vital reference for the handover decision. Further, we simplify handover signaling interaction to reduce the handover delay. Simulation results show that the proposed scheme is validated in improving network handover performance and the QoS of users under several metrics.","PeriodicalId":414672,"journal":{"name":"2021 International Conference on Networking and Network Applications (NaNA)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121701103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

DRL trains machine learning models for decision making to maximize rewards in uncertain environments such as network function virtualization (NFV). However, when facing limited information, agents often have difficulties making decisions at some decision point. In a real-world NFV environment, we may have incomplete information about network flow patterns. Compared with complete information feedback, it increases the difficulty to predict an optimal policy since important state information is missing. In this paper, we formulate a Partially Observable Markov Decision Process (POMDP) with a partially unknown NFV system. To address the shortcomings in real-world NFV, we conduct an extensive simulation to investigate the effects of adding recurrency to a Proximal Policy optimization (PPO2) by replacing the first post-convolutional fully-connected layer with a recurrent LSTM or adding stacked frames as input. The results show that RL based schedulers using stacking a history of frames in the PPO2’s input layer can easily adapt at evaluation time if the quality of observations changes.","PeriodicalId":414672,"journal":{"name":"2021 International Conference on Networking and Network Applications (NaNA)","volume":"393 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132671308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the discussion of attack technology, this paper takes SQL time-blind injection as an example to model its process with Petri Net. The validity of the model is verified by quantitative analysis and qualitative analysis. Try to inject 10, 20, 30, 40 and 50 times into target aircraft and Petri Net model respectively. The blind injection time is recorded and compared. The results show that the injection time increases with the increase of injection times. Under the same injection times, the Petri Net model takes less time. The sending time in the token can be set. When the sending time is short, the injection speed is fast, and super real-time simulation can be realized, which can realize the rapid prediction of attacks and resource vulnerability effects. When the sending time is long, the injection process slows down. It is beneficial to observe the details of the injection process and whether conflicts occur at a fine-grained level, analyze the purpose of the attack and achieve the purpose of building a patch model. The patch model can effectively take countermeasures against attacks, predict unknown vulnerabilities and ensure network information security.","PeriodicalId":414672,"journal":{"name":"2021 International Conference on Networking and Network Applications (NaNA)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130020103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Member inference attack is an attack method that threatens the privacy of training datasets. It uses the model’s behavior to infer whether the input user record belongs to the training datasets, and then get the user’s private information according to the purpose of the model. This paper studies the member inference attack under the black box model. We design a defense mechanism to make the learning model and the inference attack model learn from each other, and use the gains from the attack model to fine-tune the last layer’s parameters of the learning model. The fine-tuned learning model can reduce the gains from the membership inference attack with less loss of prediction accuracy. We use different datasets to evaluate the defense mechanism on deep neural networks. The results show that when the training accuracy and test accuracy of the learning model convergence are similar, the learning model only losses about 1% of the prediction accuracy, which the accuracy of the member inference attack drops by a maximum of around 20%.","PeriodicalId":414672,"journal":{"name":"2021 International Conference on Networking and Network Applications (NaNA)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133454050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The realization of high-performance computing offloading based on different optimization indicators (e.g., task delay and energy consumption) is currently a research hotspot in the field of mobile edge computing (MEC). This paper proposes a joint task offloading and resource allocation algorithm via proximal policy optimization for multiple terminal users and multiple MEC servers. The proposed algorithm designs the local task butter queues for terminal users and edge task butter queues for MEC servers, which allows the tasks to be executed on butter queues in a first-in-first-out way, leading to a precise calculation of waiting delays of tasks. Moreover, it formulates the objective optimization problem as the Markov decision process and employs the proximal policy optimization algorithm to minimize the weighted sum of the task delay and energy consumption. Simulation results show the proposed algorithm outperforms the baselines with better performance.","PeriodicalId":414672,"journal":{"name":"2021 International Conference on Networking and Network Applications (NaNA)","volume":"146 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133073885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
