Towards Secure and Legal E-Tendering

Tendering processes are considered to be a suitable mechanism for governments to fairly assign contracts for construction projects and procurement. The demand for efficiencies to be created in the process has resulted in a significant number of governments implementing e-tendering systems. E-tendering systems generally involve the submission of tender offer documents to a secure system hosted by the government (principal). An electronic environment presents obvious opportunities for collusion between principal and certain tenderers, fraud by tenderers and a minefield of legal uncertainties for fuelling protracted disputes. Critical examination of the security and legal requirements for e-tendering systems does not appear in the current literature. This paper identifies key security and legal issues to be addressed in the design of e-tendering systems, which may be included in e-procurement software, and proposes a new e-tendering architecture, using distributed trusted third parties which may be suitable for secure large scale operations such as the construction industry

Electronic Tendering : Guidelines and Recommendations for Successful Implementation and Uptake

Misuse case modeling for secure e-tendering system

Tendering process is utilized by principal to invited capable tenderer to participate in competitive bid for winning a large project.Due to advent of IT infrastructure, E-tendering is introduced and adopted in many countries. Yet, an electronic environment did not promise curbing collusion between principal and certain tenderers. Other than common threats to system like security breaches by malicious parties, security issue related to ethical issue like fraud and repudiation issue where no evidence existed to denied it.In this paper, common threats for e-tendering process altogether with security countermeasure are described. This three interrelated attribute (consist of tender phase, threat and security countermeasure) are illustrated in misuse case for better understanding of the risk that may occurs in particular tender phase. Furthermore, it sought to ease the system developer for designing and constructing a secure e-tendering system

A Secured Model of E-Tendering Using Unified Modeling Language Approach

E-Tendering systems remain uncertain on issues relating to legal and security compliance, in which unclear security framework is one of the issues. In te current situation, tendering systems are lacking in addressing integrity, confidentiality, authentication, and non-repudiation. Thus, ensuring the system requirements, consider security and trust issues has to be regarded as one of the challenges in developing an e-Tendering system. Therefore, this paper a model of a secured e-Tendering system using Unified Modeling Language (UML) approach. The modelling process begins with identifying the e-Tendering process, which is based on Australian Standard Code of Tendering (AS 4120-1994). It is followed by identifying the security threats and its countermeasure. The use case approach has been proven reliable in determining appropriate requirements for handling security issues. Having considered that, the outcome of this paper is a secured e-Tendering model. The model can guide developers as well as other researchers

Fair and Transparent Blockchain based Tendering Framework - A Step Towards Open Governance

Society is in constant transition to keep up with technological advancement, we are seeing traditional paradigms being increasingly challenged. The fundamentals of governance are one such paradigm. As society's values have shifted, so have expectations of government shifted from the traditional model to something commonly referred to as 'open governance'. Though a disputed term, we take open governance to mean a concept, which encourages and facilitates openness, accountability, and responsiveness to citizens. For the success of open governance initiatives, there are some technologies, such as the internet, that are crucial. These technologies enable access to both the data and to engagement activities between citizens and government. There are also other technologies, like blockchain and smart contacts, which could be utilised to assist open governance. A sound starting point would be moving from a system where information is tediously released by a government, on an 'as they please' basis, to an infrastructure where critical actions are captured with strong integrity, non-repudiation and evidential guarantees. With an added dimension that facilitates these actions record be accessible to public scrutiny in near real-time. One candidate technology for capturing such actions is blockchain. The blockchains utility is being recognised through smart contracts - potentially a vital building block to realising open and transparent government activities. In this paper, we employ the concept of smart contracts to government tendering activities. The proposed scheme is based on smart contracts, enabling a fair, transparent and independently verifiable (auditable) government tendering scheme. The scheme is then implemented on the Ethereum platform to evaluate the performance and financial cost implications, along with an evaluation of the potential security and auditability challenges.Comment: 9 Pages, 9 Figures, 4 Tables, 5 Algorithms, Conferenc

Electronic Tendering: Recognising a More Effective Use of Information Communications Technology in the Irish Construction Industry

When undertaking a traditional tender in Ireland, computer applications are heavily relied upon. Documents, from drawings to Bills of Quantities, are created with an array of computer applications. These documents are subsequently exchanged from surveying firms to a number of main contractors and, additionally, from the main contractors to subcontractors. However, even though the documents have originated in an electronicform, the majority of the documents are communicated in a paper format. Therefore, with each new communication between the parties more paperwork is created. This system of communication is inefficient and process gains can be made through the utilization of already existing Information Communication Technologies (ICT) . The thesis initially provides an analysis of the literature relating to the existing traditional tender process in the Irish construction industry. These findings are then compared with techniques being undertaken in other parts of the world, where ICT is implemented to a greater degree in the tender process. An observation study, subsequently, reveals a clearer picture of the tender process to the author. In particular, the tasks a contractor completes when pricing a competitive tender are clarified. The communication methods used by the contractor between both the PQS and subcontractors are also investigated. This investigation shows that a relatively low level of eCommunication is being undertaken by the individuals within the industry. A survey carried out by the author in the summer of 2008, establishes the current level of ICT usage in Irish construction companies with respect to the tendering process. These results show that there is a similar level of eTendering uptake to that of other countries. However, this uptake is significantly discouraged by a number of barriers identified by the author.Finally, the thesis presents an industry led pilot project. This pilot projectclarifies the potential cost savings that the Irish construction industry achieved through the application of integrated ICT tools in the construction tendering proces
