Digital contact tracing solutions have aided humanity in the first line of de-fense against the COVID-19 pandemic, but not without major technical drawbacks such as attacks against digital contact tracing technology and loss of privacy and security. The most popularly used digital contact tracing system is the decentralised DP-3T protocol and it suffers from the replay attack. A re-play attack involves taking contact tracing data from one location and re-transmitting it to another location and c...

Cybersecurity is the study of protecting information and systems. One of the most secure ways of protecting information online is through cloud services when used appropriately. In St. Mary’s university, cloud computing adaption has rapidly grown and evolved over the years. However, the protection and safety of students and staff’s information is still unsteady, which prompted the evaluation and survey of this research. In this paper, a risk analysis is performed on one of the university’s cloud...

The rising popularity of mobile payments can be attributed to the widespread use of smartphones and their applications. Despite its potential to simplify our lives, its adoption in African countries has been limited. This paper aims to enhance our understanding of the critical factors that influence the acceptance of mobile payments in Nigeria by exploring the impact of “network externalities” in addition to conventional technology acceptance factors. It posits that performance expectancy, effor...

The digital currency Hubee is an equivalent tool for all digital assets to provide a safe and convenient mobility and storage serve. Mobility (payment) or storage (settlement) of digital assets is easy to solve separately, even with traditional technologies, but when to solve both simultaneously, new technologies are needed. Therefore, in this paper, the necessary functions of digital currency are analyzed and discussed. The biggest technical difficulty in the design of digital currency is the a...

Recently, the U.S. Federal government and the Department of Defense announced the “Zero Trust” reigniting the debate on the logic of trust. Subject authentication is the core technology of cyber security. The traditional system is based on the reasoning logic of trust. The trust logic is the product of the situation that the authenticity of the subject cannot be proved, and the authenticity of the subject is remedied by a third party’s certificates. However, the authenticity of certificates stil...

Subject authentication is the core technology of cyber security. There are two existing technologies: one is PKI public key system based on trust logic, another is CPK public key system based on truth logic. In this paper, the different characteristics of trust-based PKI and evidence-based CPK different mechanisms were discussed from Four aspects: decentralized or centralized key generation, trust-based or evidence-based authentication logic, different usages of DSS signature protocol, and funct...

The majority of recently demonstrated Deep-Learning Side-Channel Attacks (DLSCAs) use neural networks trained on a segment of traces containing operations only related to the target subkey. However, when the number of training traces is restricted such as in the ASCAD database, deep-learning models always suffer from overfitting since the insufficient training data. One data-level solution is called data augmentation, which is to use the additional synthetically modified traces to act as a regul...

This paper introduces the working principle of CPK (Combined Public Key) and the general method of constructing identifier-based public key, which can not only solve the problem of key distribution, but also solve the authentication problem of identifier claimed by the subject. As basic functions, identifier authentication, identifier password, digital signature and key encryption are introduced. Where Identifier authentication is a new concept, and a separate authentication protocol is formulat...
