XML-Signcryption Based LBS Security Protocol Acceleration Methods in Mobile Distributed Computing

Intelligent XML Tag Classification Techniques for XML Encryption Improvement

“…XML Encryption is one of their leading security standards to provide the required data confidentiality by encrypting selected parts or the entire document. Flexibility of selecting specific parts of the document to be encrypted gives us the advantage to select which parts to be processed saving time and resources, However, some publications included criticism focusing on performance and representation issues [12,13] which will be discussed in literature review section…”

“…Models tend to protect XML messages in a proper way ensuring data confidentiality and authenticity, but due to the variations of XML threats [19] XML parser by sending mass amount of data To cover all mentioned threats it was challenging for proposed security models, however it can be achieved by XML Encryption [3] which can secure the whole XML document or parts within the XML message covering sensitive information from being exposed to achieve data confidentiality. Some publications showed a performance issues [13], presentation problem [21], and use of canonicalization [20] "Continue"…”

XML security – A comparative literature review

“…But not only the signature is affected by this problem, also XML Encryption suffers in the same way from the use of Canonicalization (Imamura, Clark & Maruyama 2002, Yang, Ng, Lau & Cheng 2006. (Park, Kim, Chung, Sohn & Won 2006) on the other hand refers the performance problem to the self descriptive structure of XML itself. Due to the inefficient representation of the data, XML based messages are larger and need more operating time than existing protocols as RMI, RMI/IIOP or CORBA/IIOP.…”

“…Apart from this general work on improvement of the performance, other application-specific ideas could be found. (Park, Moon, Kim, Chung & Sohn 2005) and (Park et al 2006) outline the mergence of XML Signature and Encryption for Location Based Services (LBS) in mobile environment.…”

“…Thereby XML Signature requires 60% of the whole operating time. For this reason (Park et al 2006) and (Park, Moon, Kim, Chung & Sohn 2005) deal with the development of a method to accelerate this process. Both articles tackle the "Signcryption mecha-nisms", a combination of XML Signature and Encryption already discussed in chapter 4.1.…”
