CRYPTOGRAPHY AND COMPUTER COMMUNICATIONS SECURITY M.I. ADEKA PHD UNIVERSITY OF BRADFORD 2015 CRYPTOGRAPHY AND COMPUTER COMMUNICATIONS SECURITY Extending the Human Security Perimeter through a Web of Trust Muhammad Ibn-Umar ADEKA BSc., MSc. Submitted for the Degree of Doctor of Philosophy Faculty of Engineering and Informatics University of Bradford 2015 Abstract Muhammad Ibn-Umar Adeka CRYPTOGRAPHY AND COMPUTER COMMUNICATIONS SECURITY Extending the Human Security Perimeter through a Web of Trust Keywords Human Factor; Cryptology; Cybersecurity; Communication; Risk; Authentication; Security Perimeter; Web of Trust; Secret Sharing; Cloud Data Repository This work modifies Shamir’s algorithm by sharing a random key that is used to lock up the secret data; as against sharing the data itself. This is significant in cloud computing, especially with homomorphic encryption. Using web design, the resultant scheme practically globalises secret sharing with authentications and inherent secondary applications. The work aims at improving cybersecurity via a joint exploitation of human factors and technology; a human-centred cybersecurity design as opposed to technology-centred. The completed functional scheme is tagged CDRSAS. The literature on secret sharing schemes is reviewed together with the concepts of human factors, trust, cyberspace/cryptology and an analysis on a 3-factor security assessment process. This is followed by the relevance of passwords within the context of human factors. The main research design/implementation and system performance are analysed, together with a proposal for a new antidote against 419 fraudsters. Two twin equations were invented in the investigation process; a pair each for secret sharing and a risk-centred security assessment technique. The building blocks/software used for the CDRSAS include Shamir’s algorithm, MD5, HTML5, PHP, Java, Servlets, JSP, Javascript, MySQL, JQuery, CSS, MATLAB, MS Excel, MS Visio, and Photoshop. The codes are developed in Eclipse IDE, and the Java-based system runs on Tomcat and Apache, using XAMPP Server. Its code units have passed JUnit tests. The system compares favourably with SSSS. Defeating socio-cryptanalysis in cyberspace requires strategies that are centred on human trust, trust-related human attributes, and technology. The PhD research is completed but there is scope for future work. i Acknowledgements In the words of Isaac Newton (5 February 1657), if one does not stand on the shoulders of giants, one would not achieve greater heights. Since I could not have been exempted from this golden rule, let me expend some lines to recognise a few of those who made it possible for me to be talking of a PhD Thesis at this stage of my earthly struggle. From the home base, Nigeria, I am greatly indebted to the former Chief of Army Staff (COAS), Nigerian Army (NA), Lieutenant General AB Dambazau (PhD, retired), as well as his Director of Military Intelligence (DMI), Major General AT Umaru (retired) for their moral, psychological and other supports till date. I would also like to acknowledge the roles of the Petroleum Technology Development Fund (PTDF), Abuja, Nigeria, for its scholarship, and the NA for releasing me. Specifically, mention must be made of the Executive Secretaries, PTDF, Dr Muttaqha Rabe Darma, Dr Oluwole Oluleye, Mr Femi Ajayi, Mr Aminu Ahmed Galadima and their staffs at all levels from the various departments; especially training, finance, protocol and security departments. I must also mention the former Chief of Defence Staff, Air Chief Marshal O Petinrin, former COAS, Lieutenant General OA Ihejirika and his Principal Staff Officers; especially Major General LP Ngubane (Training and Operations) and Major General SY Audu ( former DMI). I am also greatly indebted to the current COAS, Lieutenant General TY Buratai, for his interventions at critical moments. Here in the UK, I am greatly indebted to Dr M.J. Ngala of Heaton Education, Bradford, for his various facilitating efforts at linking me up with the University of Bradford, and his continuous effort to make me feel at home in Bradford; ditto to our friend, Engr. Bako Wakili, of NCC, Abuja, Nigeria. Rightly or wrongly, the success or failure of a research effort could be a reflection of the quality of supervision and other facilities; in addition to the personal disposition of the research student. It is in this context that I would like to express my profound gratitude to my supervisors, Prof. Simon J. Shepherd and Prof. Raed A. Abd- Alhameed, both of the School of Electrical Engineering and Computer Science (SoEECS), University of Bradford; for their diligence and understanding. Similarly, I am greatly indebted to the Library, ICT, Hub Research and other services of the University of Bradford, just as I am to various colleagues and staff of the SoEECS. To Dr Kelvin O. Anoh and other fellow research students, especially those in B3.26 Labs, Chesham Building, I say thank you for your positive colleagueship. Finally, my wife, Saudat, and all the children/wards – Ayatullah, Saadiq, Mawaddah, Mardiyyah, Raheemah, Muhammad, Ishaq and ‘Uncle’ Dogo; may Allah reward you all for your various supports. Ultimate gratitude is due to Allah, the Creator of His Creation; the only One that makes whatever happens to happen – out of His Wisdom. ii Dedication My wife, children, parents, brothers/sisters, teachers, friends and those who perceive themselves as enemies; those who made positive contributions to the making of Nigeria and the Nigeria Project; those who stand for humanity against the workers of iniquity from the Big Bang till Eternity; and ultimately, the Heir of all inheritors. iii Table of Contents Abstract …………………………………………………………………………………..i Acknowledgements ……. ………………………………………………………………….ii Dedication ………………………………………………………………………………....iii List of Figures …………………………………………………………………………..ix List of Tables …………………………………………………………………………..xii List of Acronyms ………………………………………………………… ……………..xiii Chapter 1 ………………………………………………………………………………….1 Introduction ………………………………………………………………………………….1 1.1 Study Background ............................................................................................ 2 1.2 Motivation and Statement of the Research Problem ........................................ 4 1.3 Aim and Objectives .......................................................................................... 6 1.4 Scope of the Research ..................................................................................... 6 1.5 Research Philosophy ....................................................................................... 7 1.5.1 Pragmatism and Mixed Methods Research Approaches ..................... 10 1.5.2 Research Methodology ........................................................................ 10 1.6 Importance and Contributions of the Research .............................................. 12 1.6.1 Key Contributions ................................................................................. 12 1.6.2 Contributions Relative to the General Research Work ......................... 14 1.7 Layout of the Thesis ....................................................................................... 15 Chapter 2 ………………………………………………………………………………..17 Trusted Secret Sharing within the Framework of Cybersecurity and Cryptology…………………………………………………………………………… …...17 2.1 Requisite Theoretical Background on Secret Sharing Schemes .................... 17 2.1.1 The Theoretical Basis for the (k, n)-Threshold Schemes .................... 17 2.1.2 An Overview of Secret Sharing Schemes ............................................ 26 2.1.3 Cryptographic Key Management .......................................................... 42 2.1.4 Key Recovery in Cryptography ............................................................. 42 2.2 A Comparative Analysis of the Various Secret Sharing Methods ................... 48 2.2.1 Classification of Secret Sharing Schemes ........................................... 49 2.2.2 The Issues Arising from Active Adversarial Models ............................. 50 2.2.3 Schemes Designed to Counter the Effects of Active Adversaries ........ 51 iv 2.2.4 Comparative Performance Analyses of Secret Sharing Schemes ....... 53 2.3 Extending the Human Security Perimeter through a Web of Trust ................. 55 2.3.1 Zimmermann’s Web of Trust ............................................................... 56 2.3.2 Human Factors and Human Infrastructure in the Context of Trust ....... 58 2.3.3 Adeka’s Web of Trust .......................................................................... 62 2.3.4 Other Models for Measuring

  • Best Practice Human Factors Guidance for Control Room/HMI Design
    Highways Consultancy Group - Highways Research Group Best Practice Human Factors Guidance for Control Room/HMI Design Contract Reference: 2/1308 Task Reference: 166(1308)MOTT Project Sponsor: Stuart White Date: November 2010 Executive Summary Control room, plant and equipment design can have a huge impact on human performance. Designing tasks, equipment and work stations to suit the user can reduce human error, accidents and ill-health. Failure to observe human factors principles can have serious consequences for individuals and for the whole organisation. Effective consideration of human factors will make work safer, healthier and more productive. The fundamental and consistent philosophy of human factors is to ensure that the human element, or user, is of principle concern within the design process. This approach promotes the inclusion of user (and operator) needs, capabilities, limitations and goals into the design process. This document contains guidance to summarise the best practice human factors approach to system/product design and development, within the general project lifecycle, in order to provide support to Highways Agency in creating more cost effective and usable designs. This guidance should prove useful to both Highways Agency project sponsors/managers and human factors specialists involved in Highways Agency system/product design and development projects. This document also contains a simple flowchart and checklist to allow the reader to determine whether the guidance is relevant to their project, and if so, which parts of the guidance should be focused on. The guidance presented in this document provides some simple steps that you can include within the project plan and supports the reader in this through raising a number of questions for consideration.

  • D2.1 – Dynamic Worker Model
    D2.1 – Dynamic worker model D2.1 –Dynamic worker model Empowering and Participatory Adap- tation of Factory Automation to Fit for Workers Abstract Smart factories are characterized by increasing automation and increasing customization. In these dynamic environments flexible and adaptive work organization is crucial, both for productivity and work satisfaction. The Factory2Fit project will support this development by developing adaptation solutions with which people with different skills, capabilities and preferences can be engaged, motivated and pro- ductive members of the work community in manufacturing industries. This deliverable describes the development of a work-related abstract profile of an employee, called Worker Model, and the development of a more dynamic worker model, Adaptive Worker Model. These models include worker characteristics and their relations with task-related, machine-related and contextual characteristics, respectively. Methodologies, standards and theories for user mod- elling development are also introduced in this deliverable. Alongside, this document provides a fur- ther analysis of the wearable measurement equipment that can be used for worker monitoring and the online worker monitoring and off-line measurements acquired from these devices. These meas- urements will be used for the definition of worker characteristics. Furthermore, an analysis of data storage mechanism that will be developed is provided.
