Cryptographic Approaches for Privacy Preservation in Location-Based Services

Emmanouil Magkos
2011 International Journal of Information Technologies and Systems Approach  
This paper surveys the current state of knowledge concerning the use of cryptographic primitives for privacy-preservation in LBS applications.  ...  Current research in location-based services (LBSs) highlights the importance of cryptographic primitives in privacy preservation for LBSs, and presents solutions that attempt to support the (apparently  ...  Based on the principle of identity-based public-key cryptography 1 , LBKs are later used to derive public keys and perform mutually authenticated key establishment with neighboring nodes, while security  ...

Reducing Dependency on Middleware for Pull Based Active Services in LBS Systems [chapter]

Saroj Kaushik, Shivendra Tiwari, Priti Goplani
2012 Lecture Notes of the Institute for Computer Sciences, Social Informatics and Telecommunications Engineering  
The trusted middleware is used to generate the authentication certificates containing the Proxy Identity (also called Pseudonyms) to fulfill the authentication requirements at the LSP servers.  ...  The middleware is the most commonly used solution to address the location privacy.  ...  Here k is the key; ID is the user identity to be encrypted; and P is the pseudonym to be generated as an output.  ...

PRIVACY PRESERVING THROUGH MEDIATOR IN DECENTRALIZED CIPHERTEXT POLICY ATTRIBUTE BASED ENCRYPTION

Varsha Thanaji Mulik .
2016 International Journal of Research in Engineering and Technology  
In the previous cryptographic approach, network security is vigorously relied on user attribute based encryption, multiple authorities and cipher text policies to make it more sheltered to some extent.  ...  In this paper, both user attributes and data attributes are used as security credentials. File security is maintained by protecting data and its location.  ...  In proposed approach, mediator is added as kind of user which enhances the security by adding the level in encryption. It provides secured management of user rights through authorities.  ...

5G-VRSec: Secure Video Reporting Service in 5G Enabled Vehicular Networks

Sang Guun Yoo
2017 Wireless Communications and Mobile Computing  
Despite an imminent arrival of the 5G communication technology, there are only a few research works done using such technology in the field of vehicular networks.  ...  In addition, it does not contemplate the management of multiple geographic/administrative regions (multiple trusted authorities) which is important in real implementations.  ...  This security mechanism will allow only LEA to manage the mapping of the unique identity of DV and 5G_ID DV .  ...

Towards Detecting and Mitigating Conflicts for Privacy and Security Requirements

Duaa Alkubaisy, Karl Cox, Haralambos Mouratidis
2019 2019 13th International Conference on Research Challenges in Information Science (RCIS)  
By using patterns to describe the problem we can propose a solution for each conflict.  ...  We will focus in this study on identification and resolution of conflicts between security and privacy requirements.  ...  Both symmetric and asymmetric algorithms may be used to provide encryption. This kind of encryption works for security requirements (Confidentiality).  ...
