Ensuring telecommunication network security through cryptology: a case of 4G and 5G LTE cellular network providers

This paper aims to present the details regarding telecommunication network security through cryptology protocols. The data was based on scientific data collection and the quantitative method was adopted. The questionnaire was developed and the primary respondents were approached who were working in 4 telecommunication networking companies namely Huawei, Ericsson, SK Telecom and Telefonica. The sample size of the research was 60 participants and the statistical analysis was used to analyze research. The finding shows that cryptology protocol such as SSH, SSL, Kerberos PGP and SET are implemented within the companies in order to secure network

Public key cryptography in resource-constrained WSN

In this paper we present a detailed review of the works on public key cryptography (PKC) in wireless sensor networks (WSNs). In the early days of sensor networks, public key cryptography was thought to be completely unfeasible considering its computational complexity and energy requirements. By this time, several works have proved that the lightweight versions of many well-known public key algorithms can be utilized in WSN environment. With the expense of a little energy, public key based schemes could in fact be the best choice for ensuring data security in high-security demanding WSN applications. Here, we talk about the notion of public key cryptography in WSN, its applicability, challenges in its implementation, and present a detailed study of the significant works on PKC in WSN

Secure Mutual Self-Authenticable Mechanism for Wearable Devices

YesDue to the limited communication range of wearable devices, there is the need for wearable devices to communicate amongst themselves, supporting devices and the internet or to the internet. Most wearable devices are not internet enabled and most often need an internet enabled broker device or intermediate device in order to reach the internet. For a secure end to end communication between these devices security measures like authentication must be put in place in other to prevent unauthorised access to information given the sensitivity of the information collected and transmitted. Therefore, there are other existing authentication solutions for wearable devices but these solutions actively involve from time to time the user of the device which is prone to a lot of challenges. As a solution to these challenges, this paper proposes a secure point-to-point Self-authentication mechanism that involves device to device interaction. This work exploits existing standards and framework like NFC, PPP, EAP etc. in other to achieve a device compatible secure authentication protocol amongst wearable device and supporting devices.

Enhancement the security of WSN using ALARM protocol to Prevention from Reply Attack

The wireless Ad hoc network is the self configuring type of network. In self configuring type of networks mobile nodes can leave or join the network when they want .In such type of networks many inside and outside attacks are possible. Inside and outside attacks are broadly classified as active and passive attacks. To prevent inside and outside attacks trust relationship between the mobile nodes must be maintained. The trust relationship between the mobile nodes is provided by mutual authentication. ALARM is the protocol for providing trust relationship between the mobile nodes. In this protocol the clocks of the mobile nodes are weakly synchronized by using GPS. In such case reply attack is possible. To prevent reply attack clocks of the mobile nodes must be strongly synchronized. In our new proposed technique, we are enhancing t the ALARM protocol to provide strong clock synchronization between the mobile nodes. Our new technique will be based on the NTP (network time protocol). Keywords— ALARM, Attacks, clock Synchronization, GPS, NT

Access Point Security Service for wireless ad-hoc communication

This paper describes the design and implementation of a security solution for ad-hoc peer-to-peer communication. The security solution is based on a scenario where two wireless devices require secure communication, but share no security relationship a priori. The necessary requirements for the security solution described here comprise topics such as energy efficiency, security standards and ad-hoc networks. The devised solution is called Access Point Security Service (APSS). APSS is able to provide security by delivering a symmetric key to two wireless devices that require ad-hoc peer-to-peer communication. The main principle of APSS is that it makes use of an existing security relationship between a network provider and its customers. The existing security relationship enables the network provider to deliver security to two or more communicating parties in the form of a shared key. An implementation of APSS is provided making use of the existing Wi-Fi security standards
