Abstract5G is the next generation of mobile communication systems. As it is being finalized, the specification is stable enough to allow giving an overview. This paper presents the security aspects of the 5G system specified by the 3 rd Generation Partnership Project (3GPP), especially highlighting the differences to the 4G (LTE) system. The most important 5G security enhancements are access agnostic primary authentication with home control, security key establishment and management, security for mobility, service based architecture security, inter-network security, privacy and security for services provided over 5G with secondary authentication.
The 5 th Generation (5G) of mobile communication systems will bring massive changes in the dynamics of the Information and Communication Technology (ICT) industry. The applications of 5G technology are well-positioned to address the ever-increasing demand for enhanced service experience. With digitization on its way to touch every part of life, Internet of Things (IoT) will be integral part of 5G from the very beginning; this is unlike 4G where IoT came later. However, open issues such as market demand, technical viability, economic feasibility of adopting 5G and related business dynamics do exist. This paper discusses such issues and more importantly, the security considerations in the world where everything will be connected.
Mobile communication systems are ubiquitous nowadays. The main requirements of these networks are privacy and security of the subscriber as well as a high performance. To provide these properties the 3GPP (Third Generation Partnership Project) developed the LTE (Long Term Evolution) mobile communication network which is deployed worldwide.In this paper, we give a brief overview of the LTE Network Architecture as well as a look on the security mechanism as defined by 3GPP. We describe the security architecture and discuss possible threats and attacks on the core and on the access network. Due to these possible attacks we developed a program which is able to extract certain security relevant information out of the message flow in real time and to detect a possible attach flood attack. Finally, we validate the function of the program with three test cases and discuss the impact of such flood attacks on the LTE network and other future work to extend it to other protocol exchanges.
This paper reports a design and fabrication of a functional nano robot “Sootha Vennai Parpamcutâvanai – Parpam – SVP” of 150-200 nm size which behaves more or less like a human physician in nano form inside the body. This nanorobot is a medicine which has artificial intelligence i.e. the distinguishing ability, decision making ability and some basic behavioral properties such as target detection ability, self-propelling capability and handling the infection in the case of breast cancer. This nanorobot can also aid in cancer therapy, site-specific or target drug delivery, and tissue repair.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
