In this paper we describe an image-based approach to finding location-based information from camera-equipped mobile devices. We introduce a point-by-photograph paradigm, where users can specify a location simply by taking pictures. Our technique uses content-based image retrieval methods to search the web or other databases for matching images and their source pages to find relevant location-based
Uppsatsen syftar till att förtydliga det ansvar som åligger stater till följd av en enskild stats allvarliga brott mot en folkrättsligt tvingande norm. Genom att använda ett rådgivande yttrande från juli 2024, i vilket Internationella domsto-len konstaterade Israels ockupation av de palestinska territorierna som olaglig, undersöks statsansvaret. Avgörandet aktualiserar tre skyldigheter för tredje The essay aims to clarify the responsibility of States arising from a serious breach of a peremptory norm by another State. It does so by using the adviso-ry opinion of July 2024, in which the International Court of Justice found Israel’s occupation of the Palestinian territories unlawful. The Courts ruling raised three obligations for third States: the obligation not to recognize the situation as
Network Data Analytics Function (NWDAF) is a key component in 5G networks, introduced by 3G Partnership Project (3GPP) standards, that leverages machine learning to optimize network performance. The 3GPP standards mandate that mobile network operators should retrain NWDAF models to maintain accuracy. However, the presence of adversarial user equipment (UE) can introduce corrupted data points durin
The size of the authentication tag represents a significant overhead for applications that are limited by bandwidth or memory. Hence, some authenticated encryption designs have a smaller tag than the required privacy level, which was also suggested by the NIST lightweight cryptography standardization project. In the ToSC 2022, two papers have raised questions about the IND-CCA security of AEAD sch
Advances in software virtualization and network processing lead to increasing network softwarization. Software network elements running on commodity platforms replace or complement hardware components in cloud and mobile network infrastructure. However, such commodity platforms have a large attack surface and often lack granular control and tight integration of the underlying hardware and software

The digital twin is a rather new industrial control and automation systems concept. While the approach so far has gained interest mainly due to capabilities to make advanced simulations and optimizations, recently the possibilities for enhanced security have got attention within the research community. In this paper, we discuss how a digital twin replication model and corresponding security archit
Efficient protection of huge amount of IoT produced data is key for wide scale data analytic services. The most efficient way is to use pure symmetric encryption as that allows both fast decryption at the analytic engine side as well as energy efficient encryption at the IoT side. However, symmetric encryption can only be performed if there is a way to directly map an encrypted object to the corre
Denna uppsats har undersökt förhållandet mellan tredjestatskontraåtgärder (på engelska third-party countermeasures) enligt statsansvarsreglerna och FN:s säkerhetsråds mandat att vidta åtgärder mot enskilda stater enligt kapitel VII i FN-stadgan. Tredjestatskontraåtgärder innebär att en stat utan att vara skadad av folkrättsbrottet ifråga vidtar kontraåtgärder mot en annan stat som brutit mot förpl

Due to limitations of IoT networks including limited bandwidth, memory, battery, etc., secure multicast group communication has gained more attention, and to enable that a group key establishment scheme is required to share the secret key among the group members. The current group key establishment protocols were mostly designed for Wireless Sensor Network, and they require device interaction, hig
Internet of Things (IoT) firmware upgrade has turned out to be a challenging task with respect to security. While Over-The-Air (OTA) software upgrade possibility is an essential feature to achieve security, it is also most sensitive to attacks and lots of different firmware upgrade attacks have been presented in the literature. Several security solutions exist to tackle these problems. We observe
The growing diversity of connected devices leads to complex network deployments, often made up of endpoints that implement in- compatible network application protocols. Communication between heterogeneous network protocols was traditionally enabled by hardware translators or gateways. However, such solutions are increasingly unfit to address the security, scalability, and latency requirements of m
In this paper, we investigate the security of SNOW-V, demonstrating two guess-and-determine (GnD) attacks against the full version with complexities 2384 and 2378, respectively, and one distinguishing attack against a reduced variant with complexity 2303 . Our GnD attacks use enumeration with recursion to explore valid guessing paths, and try to truncate as many invalid guessing paths as possible
