The evolving area of the upcoming technology in the era of “Mobile Security” is a 5G network. The aim of this technology is to provide security to the mobile nodes for the load balancing, for the voice security, capacity, quality of services, secure end-to-end communication, connectivity of the devices in a highly mobile network with reliable and scalable networks. The enhancement towards technology leads to connect home appliances with IoT devices, industries, business. Therefore, security-related issues will also increase. In wireless communication, devices want to connect all the time, which primes the vulnerabilities, increases network traffic at the device side on the channel, and creates the backdoor for the hacking and cracking mechanisms for the wireless devices.
TopIntroduction
5G is not individual around “quicker, superior or improved” networks, it is all about distressing approximately every characteristic of our subsists and empowering an assorted innovative customary of amenities. Nevertheless, 5G have their potential, that is, its applications must be distributed very strongly and sanctuary matters essential remain dispensed through the system foundation since from the self-same commencement towards defending equally the systems and clients. Along with 5G, the mobile network takes that security on another close with an extensive diversity of innovative, forward-thinking precautions (McKeown N et.al.,2008). This Chapter pronounces those precautions in deepness, as well as the susceptibilities and bout paths, they are intended towards moderate. Safeguarding mutual equal level of security for all tenders which shape slicing notion, in this case, can also be difficult. There are several features of slicing i.e., isolation and protection might create attack methods such as weak isolation will lead to another resource with better parameters, lower cost. From the industry point of view, following eight major necessities of 5G are recognized (Ericsson,2015):
- •
1~10 Gbps data rates in physical networks: This data rate is almost 10 times faster than the existing LTE networks that are 150 Mbps.
- •
Round trip latency is 1 ms: It is almost 10 times faster than 4G’s RTT.
- •
High bandwidth in the unit area: It will increase the connectivity of the devices with very high bandwidth.
- •
An enormous number of connected devices: It will connect thousands of devices in one go.
- •
Availability of network: 99.99% network will be available in 5G.
- •
Coverage of network anytime, any ware: Network should be available anytime as per user location.
- •
Energy consumption should be reduced: Development of technology will lead the usage of 5G network energy consumption is reduced by almost 99%
- •
High battery life: It is very important in the emerging 5G network is that it reduce power consumption.
Many of the wireless industries, university, and research officialdoms have started working in 5G wireless systems such as Ericsson, Qualcomm, Docomo, Huawei, Nokia Solution Networks, METIS, Samsung electronics, 5G training, 5G Forum, 5GNOW. Visions of these companies discussed in the table 1 and reference in table 2 (Ericsson,2015):
