But most security systems are based on complex algorithms that require a high complexity and energy consumption, thus have undesirable consequences. To reduce them, a new security system called E3SN is defined. It is based on an invertible and flexible key dependent matrix to mix the contents of the packets. Our proposal can achieve simultaneously the information's confidentiality, packet's integrity and source's authentication, with a minimum of computational complexity, communication overhead and memory consumption. This matrix is secret and only the transmitter and receiver can produce it in counter mode. We evaluate our system by comparing E3SN to AES algorithm, considered reliable and robust in several standards of sensor networks such as ZigBee, WirelessHART and ISA100.11a. The results show that the proposed technique is much more efficient than AES, with the same quality of cryptography.","PeriodicalId":174026,"journal":{"name":"2013 International Conference on Security and Cryptography (SECRYPT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130915150","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}

Our approach assumes giving minimal information to adversaries and the best responsiveness of the system regardless of user representation or possible usage. We consider keystroking not only in the context of keyboard, but also touch screen, pin pad and any other input device that could be used for typing.

However, important limitations prevent any real deployment. On the first hand, fingerprinting has a low accuracy when the devices have similar hardware and software. On the second hand, attackers may forge signatures to impersonate devices. We propose Diversity, a cooperative fingerprinting approach that improves accuracy of existing fingerprinting methods while relying only on off-the-shelf hardware. Diversity improves fingerprinting up to the reliable individual identification of identical 802.11 devices. This approach modifies the signature of devices by modifying slightly their traffic attributes. We evaluate Diversity with both a simulation and an implementation, achieving a false positive rate of 0% with a dataset including identical devices. Finally, we complement Diversity by mechanisms for detecting attackers that try to forge signatures.","PeriodicalId":174026,"journal":{"name":"2013 International Conference on Security and Cryptography (SECRYPT)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131897009","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}

At the same time, MINHO detects any tries for unauthorized access by attackers. Our idea is to use a mobile phone to send a request with specific parameters to the service provider before the actual authentication process, then, the service provider verifies the pre-authentication parameters during the authentication process. We propose many parameters that can be used with the pre-authentication service such as Authentication Ticket (AT), time, and location. MINHO is a practical scheme that can be used with the current systems, without (hardware/software) changes on the terminal side. It is a cost effective scheme, easy to use, and does not rely on a third party.","PeriodicalId":174026,"journal":{"name":"2013 International Conference on Security and Cryptography (SECRYPT)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121076211","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}

Consequently, we can improve the memory complexity of the previous preimage attack on full MD5 from 245 to 213 and on full 4-pass HAVAL from 264 to 232.

However, they are not typically used because of their relative inefficiency in computing polynomial operations when compared to conventional prime or binary Galois fields. The purpose of this research was to design and implement characteristic 3 Galois field arithmetic algorithms with greater overall efficiency than those presented in current literature, and to evaluate their applicability to elliptic curve cryptography. The algorithms designed were tested in a C++ program and using a mapping of field element logarithms, were able to simplify the operations of polynomial multiplication, division, cubing, and modular reduction to that of basic integer operations. They thus significantly outperformed the best characteristic 3 algorithms presented in literature and showed a distinct applicability to elliptic curve cryptosystems. In conclusion, this research presents a novel method of optimizing the performance of characteristic 3 Galois fields and has major implications for the field of elliptic curve cryptography.","PeriodicalId":174026,"journal":{"name":"2013 International Conference on Security and Cryptography (SECRYPT)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130062052","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 experiment indicates that attackers are gaining interest in IPv6 networks and appropriate security tools need to be readied. Therefore, we propose HoneydV6, a low-interaction IPv6 honeypot that can simulate entire IPv6 networks and which may be utilized to detect and analyze IPv6 network attacks. Our implementation extends the well-known low-interaction honeypot Honeyd. To the best of our knowledge, this is the first low-interaction honeypot which is able to simulate entire IPv6 networks on a single host. The huge IPv6 address spaces requires new approaches and concepts in order to enable attackers to find and exploit a honeypot. We increase the chance for an attacker to find a target host in our IPv6 honeypot by reacting to the attacker's requests with the dynamic generation of new IPv6 host instances in the honeynet.","PeriodicalId":174026,"journal":{"name":"2013 International Conference on Security and Cryptography (SECRYPT)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134444596","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}

One negative case scenario is the political affiliation profiling. Our hypothesis is that this scenario is nowadays realistic, applicable to social media, and violates civil rights, privacy and freedom. To demonstrate this, we developed a horror story, i.e., a Panopticon method, in order to reveal this threat and contribute in raising the social awareness over it. The Panopticon relies on data/opinion mining techniques; hence it classifies comments, videos and playlists, collected from the popular social medium YouTube. Afterwards, it aggregates these classifications in order to decide over the users' political affiliation. The experimental test case of the Panopticon is an extensive Greek community of YouTube users. In order to demonstrate our case, we performed an extensive graph theoretical and content analysis of the collected dataset and show how and what kind of personal data (e.g. political attitude) can be derived via data mining on publicly available YouTube data. Then, we provide the reader with an analysis of the legal means that are available today, to a citizen or a society as a whole, so as to effectively be prevented from such a threat.","PeriodicalId":174026,"journal":{"name":"2013 International Conference on Security and Cryptography (SECRYPT)","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133338403","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}
