A Marketplace for Efficient and Secure Caching for IoT Applications in 5G Networks
As the communication industry is progressing towards
fifth generation (5G) of cellular networks, the traffic it
carries is also shifting from high data rate traffic from cellular
users to a mixture of high data rate and low data rate traffic
from Internet of Things (IoT) applications. Moreover, the need
to efficiently access Internet data is also increasing across 5G
networks. Caching contents at the network edge is considered
as a promising approach to reduce the delivery time. In this
paper, we propose a marketplace for providing a number of
caching options for a broad range of applications. In addition,
we propose a security scheme to secure the caching contents
with a simultaneous potential of reducing the duplicate contents
from the caching server by dividing a file into smaller chunks.
We model different caching scenarios in NS-3 and present the
performance evaluation of our proposal in terms of latency and
throughput gains for various chunk sizes
Securing library information system: Vulnerabilities and threats
Threats and vulnerabilities in computers and networks are common nowadays since computers are widely used by the
public. The risks of computer threats and vulnerabilities are high since most computers are connected to the internet.
Library Information Systems is also vulnerable to attack since it is a public access institution. Majority of users are naive when it comes to computer and network securities. Some breaches in Library Information System are intentional and some are unintentional. Risks analysis should be done to find the threats and risks in designing the Library Information System. Threats are made possible due to lack of proper procedures, software flaws and policies. The administrators should anticipate all the possible attacks and their mitigation techniques. In this paper, we will try to address various issues arise from this vulnerabilities and threats. We will also describe how we can reduce and overcome this vulnerabilities and threats
