The aim of this reprint focuses on the latest protocol research, software/hardware development and implementation, and system architecture design in addressing emerging security and privacy issues for modern wireless communication networks. Relevant topics include, but are not limited to, the following: deep-learning-based security and privacy design; covert communications; information-theoretical foundations for advanced security and privacy techniques; lightweight cryptography for power constrained networks; physical layer key generation; prototypes and testbeds for security and privacy solutions; encryption and decryption algorithm for low-latency constrained networks; security protocols for modern wireless communication networks; network intrusion detection; physical layer design with security consideration; anonymity in data transmission; vulnerabilities in security and privacy in modern wireless communication networks; challenges of security and privacy in node–edge–cloud computation; security and privacy design for low-power wide-area IoT networks; security and privacy design for vehicle networks; security and privacy design for underwater communications networks
Blown to Bits: Your Life, Liberty, and Happiness After the Digital Explosion
382 p.Libro ElectrĂłnicoEach of us has been in the computing field for more than 40 years. The book is the product of a lifetime of observing and participating in the changes it has brought. Each of us has been both a teacher and a learner in the field.
This book emerged from a general education course we have taught at Harvard, but it is not a textbook. We wrote this book to share what wisdom we have with as many people as we can reach. We try to paint a big picture,
with dozens of illuminating anecdotes as the brushstrokes. We aim to entertain you at the same time as we provoke your thinking.Preface

Development of a secure multi-factor authentication algorithm for mobile money applications
A Thesis Submitted in Fulfillment of the Requirements for the Degree of Doctor of Philosophy in Information and Communication Science and Engineering of the Nelson Mandela African Institution of Science and TechnologyWith the evolution of industry 4.0, financial technologies have become paramount and mobile
money as one of the financial technologies has immensely contributed to improving financial
inclusion among the unbanked population. Several mobile money schemes were developed but,
they suffered severe authentication security challenges since they implemented two-factor
authentication. This study focused on developing a secure multi-factor authentication (MFA)
algorithm for mobile money applications. It uses personal identification numbers, one-time
passwords, biometric fingerprints, and quick response codes to authenticate and authorize mobile
money subscribers. Secure hash algorithm-256, Rivest-Shamir-Adleman encryption, and Fernet
encryption were used to secure the authentication factors, confidential financial information and
data before transmission to the remote databases. A literature review, survey, evolutionary
prototyping model, and heuristic evaluation and usability testing methods were used to identify
authentication issues, develop prototypes of native genuine mobile money (G-MoMo)
applications, and identify usability issues with the interface designs and ascertain their usability,
respectively. The results of the review grouped the threat models into attacks against privacy,
authentication, confidentiality, integrity, and availability. The survey identified authentication
attacks, identity theft, phishing attacks, and PIN sharing as the key mobile money systems’
security issues. The researcher designed a secure MFA algorithm for mobile money applications
and developed three native G-MoMo applications to implement the designed algorithm to prove
the feasibility of the algorithm and that it provided robust security. The algorithm was resilient to
non-repudiation, ensured strong authentication security, data confidentiality, integrity, privacy,
and user anonymity, was highly effective against several attacks but had high communication
overhead and computational costs. Nevertheless, the heuristic evaluation results showed that the
G-MoMo applications’ interface designs lacked forward navigation buttons, uniformity in the
applications’ menu titles, search fields, actions needed for recovery, and help and documentation.
Similarly, the usability testing revealed that they were easy to learn, effective, efficient,
memorable, with few errors, subscriber satisfaction, easy to use, aesthetic, easy to integrate, and
understandable. Implementing a secure mobile money authentication and authorisation by
combining multiple factors which are securely stored helps mobile money subscribers and other
stakeholders to have trust in the developed native G-MoMo applications
