A Decentralized BYOD Authentication System secure against ReEntrancy Attacks
Mohd Mamoon, Mohammad Abu Huraira Saim, Ilma Shah, Abdus Samad · 2023
The concept of BYOD has been around in the corporate world for a while now which allows employees to bring and use personal devices for organizational work. However, the onset of such a trend also brought major security issues leading to compromise in the organization’s data and resources. Current solutions to such security issues do exist, nevertheless, most of them are bound by constraints and may also face backlash from the workforce community. Blockchain technology has the potential to address the security threats associated with BYOD by providing decentralized authentication, immutable records and employing signature-based algorithms. In this paper, an Ethereum-based blockchain application has been proposed using smart contracts to authenticate employees’ devices and detect unauthorized access. This paper also explains how blockchain can be adopted to address the issue of ReEntrancy attacks where a malicious user can exploit vulnerabilities in smart contracts and steal funds from decentralized applications.
