It is common that attackers add adversarial perturbation to a normal image in order to fool the models. The N-pixel attack is one of the recently popular adversarial methods by simply changing a few pixels in the image. We observe that changing the few pixels leads to an obvious difference with its neighboring pixels. Therefore, this research aims to defend the N-pixel attacks based on image reconstruction. We develop a three-staged reconstructing algorithm to recover the fooling images. Experimental results show that the accuracy of CIFAR-10 test dataset can reach 92% after applying our proposed algorithm, indicating that the algorithm can maintain the original inference accuracy on normal dataset. Besides, the effectiveness of defending N-pixel attacks is also validated by reconstructing 500 attacked images using the proposed algorithm. The results show that we have a 90% to 92% chance of successful defense, where N=1,3,5,10,and 15.","PeriodicalId":312816,"journal":{"name":"Proceedings of the 8th International Workshop on Security in Blockchain and Cloud Computing","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114296768","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}

In terms of efficiency, symmetric key-based searchable encryption is promising for practical deployment and has been a rich area of research. In the literature, there are mainly two lines of research accordingly: searchable symmetric encryption (SSE) for encrypted matching queries and order-preserving or order-revealing encryption (OPE/ORE) for encrypted range queries. Despite the efficiency, these searchable encryption techniques all allow leakages in their security frameworks and have been shown to be vulnerable to various attacks in recent years. There has been little work regarding a comprehensive investigation on these attacks. In this paper, we provide a systematic survey on the recent advances on attacks in efficient encrypted cloud data search backed by SSE or OPE/ORE. Specifically, we first provide a categorization of the adversary model from diverse dimensions. Then we systematically examine the existing attacks against SSE and OPE/ORE under different adversary types and the leakages allowed in the security frameworks. The goal of this paper is to provide pointers for understanding the security of efficient searchable encryption techniques and to call for further motivated research activities.","PeriodicalId":312816,"journal":{"name":"Proceedings of the 8th International Workshop on Security in Blockchain and Cloud Computing","volume":"270 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125828210","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}
