Secure electronic tendering

Du, Rong (2007) Secure electronic tendering. PhD thesis, Queensland University of Technology.


Tendering is a method for entering into a sales contract. Numerous electronic

tendering systems have been established with the intent of improving the efficiency

of the tendering process. Although providing adequate security services

is a desired feature in an e-tendering system, current e-tendering systems are

usually designed with little consideration of security and legal compliance.

This research focuses on designing secure protocols for e-tendering systems.

It involves developing methodologies for establishing security requirements, constructing

security protocols and using formal methods in protocol security verification.

The implication is that it may prove suitable for developing secure

protocols in other electronic business domains.

In depth investigations are conducted into a range of issues in relation to establishing

generic security requirements for e-tendering systems. The outcomes are

presented in a form of basic and advanced security requirements for e-tendering

process. This analysis shows that advanced security services are required to secure

e-tender negotiation integrity and the submission process.

Two generic issues discovered in the course of this research, functional difference

and functional limitations, are fundamental in constructing secure protocols

for tender negotiation and submission processes. Functional difference identification

derives advanced security requirements. Functional limitation assessment

defines how the logic of generic security mechanisms should be constructed. These

principles form a proactive analysis applied prior to the construction of security


Security protocols have been successfully constructed using generic cryptographic

security mechanisms. These protocols are secure e-tender negotiation

integrity protocol suite, and secure e-tender submission protocols. Their security

has been verified progressively during the design. Verification results show that

protocols are secure against common threat scenarios. The primary contribution of this stage are the procedures developed for the complex e-business protocol

analysis using formal methods. The research shows that proactive analysis has

made this formal security verification possible and practical for complex protocols.

These primary outcomes have raised awareness of security issues in e-tendering.

The security solutions proposed in the protocol format are the first in e-tendering

with verifiable security against common threat scenarios, and which are also practical

for implementation. The procedures developed for securing the e-tendering

process are generic and can be applied to other business domains. The study

has made improvements in: establishing adequate security for a business process;

applying proactive analysis prior to secure protocol construction; and verifying

security of complex e-business protocols using tool aided formal methods.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
