A Privacy-Preserving Secure Service Discovery Protocol for Ubiquitous Computing Environments
نویسندگان
چکیده
Recently, numerous service discovery protocols have been introduced in the open literature. Unfortunately, many of them did not consider security issues, and for those that did, many security and privacy problems still remain. One important issue is to protect the privacy of a service provider while enabling an end-user to search an alternative service using multiple keywords. To deal with this issue, the existing protocols assumed that a directory server should be trusted or owned by each service provider. However, an adversary may compromise the directory server due to its openness property. In this paper, we suggest an efficient method of membership verification to resolve this issue and analyze its performance. Using this method, we propose a privacy-preserving secure service discovery protocol protecting the privacy of a service provider while providing multiple keywords search to an end-user. Also, we provide performance and security analysis of our protocol.

A Lightweight, Privacy Preserving and Secure Service Discovery Protocol in Ubiquitous Computing Environment
During service discovery, preserving privacy of end users and service providers is one of the challenging research issues in ubiquitous computing environment (UCE). To solve this issue, we define service group and classify it into two cases: public service and private service. End users’ privacy is important in public service group while privacy of end users and service providers are important ...

Recently, the technologies for child care and safety have been developing rapidly, together with the various IT convergence services. In particular, several mobile operators (e.g., SKT, KTF, and LGT) in Korea and Gangnam province in Seoul provide their own child-care services. However, someproblems such as incorrect location information, privacy violation, and difficulty of an end-user to contr...
متن کاملPrivacy Preserving Collaborative Filtering using Biclustering in Ubiquitous Computing Environments
Privacy concerns are a major hurdle in the success of personalized services in ubiquitous computing environments. Personalized recommendations are usually served using Collaborative Filtering techniques. In this paper, we propose a framework for privacy preserving collaborative filtering in ubiquitous computing environments. The proposed framework is based on a biclustering algorithm which empl...
متن کاملNinja: Non Identity Based, Privacy Preserving Authentication for Ubiquitous Environments
Most of today’s authentication schemes involve verifying the identity of a principal in some way. This process is commonly known as entity authentication. In emerging ubiquitous computing paradigms which are highly dynamic and mobile in nature, entity authentication may not be sufficient or even appropriate, especially if a principal’s privacy is to be protected. In order to preserve privacy, o...
متن کاملA Privacy-Aware Service Protocol for Ubiquitous Computing Environments
In a ubiquitous computing environment, every service should have the characteristic of context-awareness and location information is an important factor to grasp a user’s context. Thus, location privacy is an major security issue of ubiquitous computing environment. Most research on location privacy is focused on protecting the location information itself. However, not only prohibiting acquirem...
