XML Security — A Comparative Literature Review <s> XML Security for LBS <s> Location-based services refers to value-added service by processing information utilizing mobile user location. With the rapidly increasing wireless Internet subscribers and world LBS market, the various location based applications are introduced such as buddy finder, proximity and security services. As the killer application of the wireless Internet, the LBS has reconsidered technology about location determination technology, LBS middleware server for various application, and diverse contents processing technology. However, there are fears that this new wealth of personal location information will lead to new security risks, and invasion of the privacy of people and organizations. In this paper, we suggest security acceleration methods for fast open LBS using XML signcryption mechanism. And proposed secure LBS security protocols allows a client to offload mobile certificate handling to the server and to enable the central administration of privacy policies. The idea is to create a signcryption technique for software based XML signature acceleration. <s> BIB001 </s> XML Security — A Comparative Literature Review <s> XML Security for LBS <s> This paper describes the open security architecture for LBS (Location- based Services) platform ensuring interoperability among the wireless networks and various location-based application services and the functional security requirements for the LBS platform. The goal of this paper is to investigate how well the most limited wireless devices can make use of LBS security services. In this paper, we suggest security acceleration methods for high speed open LBS using XML signcryption mechanism. And proposed secure LBS security protocols allows a client to offload mobile certificate handling to the server and to enable the central administration of privacy polices.

The Korean Information Security Research Division of the Electronic and Telecommunication Research Institute (ETRI) is working on the integration of XML Security with Location Based Systems (LBS). In section 4.1, a short introduction in this technology and the arising performance problems was given. Despite these problems  ) develops a key management system based on XKMS and Web Services. Trust is established by a one-time activity per session (Single-Sign On) or by evaluating dynamically on every request. For simulation Single-Sign On was selected and implemented by using SAML. The transaction model consists of the three main actors: LBS application, SAML processor and XKMS Service. Simulation results show that up to a number of 45 clients the system runs stably under the defined conditions. Thereby XML Signature requires 60% of the whole operating time. For this reason BIB002 and BIB001 deal with the development of a method to accelerate this process. Both articles tackle the "Signcryption mechanisms", a combination of XML Signature and Encryption already discussed in chapter 4.1. For this purpose the architecture was taken from  ). An implementation of this mechanism with JCE (Java Crypto Extension) and SAX supplies better performance compared to the traditional method while integrity and confidentiality are still preserved. This field seems to be a promising application area in the future as well.
