Privacy enhanced mutual authentication in LTE
2013
In this paper we propose a way to enhance the identity privacy in LTE/LTE-Advanced systems. This is achieved while minimizing the impact on the existing E-UTRAN system. This is important since proposals to modify a widely deployed infrastructure must be cost effective, both in terms of design changes and in terms of deployment cost. In our proposal, the user equipment (UE) identifies itself with a dummy identity, consisting only of the mobile nation code and the mobile network code. We use the existing signalling mechanisms in a novel way to request a special encrypted identity information element. This element is protected using identity-based encryption (IBE), with the home network (HPLMN…
Analysis and Optimization Technique of Secure Smart Grid Communication Network for Sustainable Development
2019
The smart network includes many sub-frameworks, for example, the Home Area Network (HAN), which are at risk and prone to be attacked remotely. A smart grid communication is meant to design a mutual authentication scheme and a key management protocol. This study is aimed with an efficient arrangement for HAN that analyzes a framework set-up for HAN. In this paper, we have analyzed three cases: First, we show the normal execution then execution along with attackers. Using mutual authentication, we overcome attacks. It has introduced a number of routing schemes for grid networks in recent years, and they provide different level of privacy protection at different cost. First, an unspecified key…
Mutual entity authentication for LTE
2011
In this paper we outline the Authentication and Key Agreement protocol (EPS-AKA) found in Long-Term Evolution (LTE) systems. This architecture is the 3GPP version of a 4G access security architecture. The LTE security architecture is a mature evolved architecture, with both strengths and weaknesses. In this paper we propose an amendment to the EPS-AKA protocol to make it a full mutual (online) entity authentication protocol. We also analyze the proposal, highlighting both the improvements and the drawbacks of the new AKA protocol.
A Proposed Access Control-Based Privacy Preservation Model to Share Healthcare Data in Cloud
2020
Healthcare data in cloud computing facilitates the treatment of patients efficiently by sharing information about personal health data between the healthcare providers for medical consultation. Furthermore, retaining the confidentiality of data and patients' identity is a another challenging task. This paper presents the concept of an access control-based (AC) privacy preservation model for the mutual authentication of users and data owners in the proposed digital system. The proposed model offers a high-security guarantee and high efficiency. The proposed digital system consists of four different entities, user, data owner, cloud server, and key generation center (KGC). This approach makes…
Formal Analysis and Model Checking of a Group Authentication Protocol by Scyther
2016
Scyther [1] is designed to check the security and vulnerabilities of security protocols. In this paper, we use Scyther to analyze two discrete logarithm problem (DLP) based group authentication protocols proposed in [2]. These two protocols are claimed to satisfy several security requirements, but only part of them have been checked because of the properties and limitations of Scyther. Some positive results have been gained and show that the protocols provide mutual authentication and implicit key authentication and are secure against impersonation attack. An important innovation in this paper is that we have extended the expressing ability of Scyther by giving some reasonable assumption du…
