As the sensitive use of SMS grows every day, researchers have been devising ways to secure it. However, some of the algorithms proposed by researchers or solutions that have flooded the market have not fully aided SMS security, making it difficult to choose appropriate solutions that align with users' needs, which is key to protecting sensitive information. Finding the right solution to secure SMS is still a problem today in sectors like banking, E-commerce and even individual usage. The idea of using encryption is not new, but employing the right solution to secure SMS is yet to be achieved by all. In this thesis, we analyzed and evaluated AES, Camellia and RC6 algorithms for securing SMS on Android platform and over the network. A comparative study was carried out on these algorithms using performance metrics: Encryption, decryption, and key generation time. The result shows that Camellia with key sizes 128, 192 and 256 bits was the fastest to encrypt a text while RC6 with key sizes 128, 192 and 256 bits was the fastest to decrypt a text. Camellia and RC6 with key sizes 128, 192 and 256 bits generate keys at almost the same speed. AES of key sizes 128, 192 and 256 bits was slower in generating keys, encrypting and decrypting a message when compared to Camellia and RC6. The findings from this research support the idea of using Camellia and RC6 more often for SMS encryption.

The banking sector is undergoing a significant transformation in the work environment, driven by the widespread adoption of technological tools and remote work models, particularly in the wake of the COVID-19 pandemic. This study highlights the perspectives and experiences of bank managers in navigating this digital shift, examining the effectiveness of technological tools in supporting remote work and the challenges faced by administrative leaders in managing virtual teams. The research employed a mixed-methodology approach, including in-depth interviews with a sample of bank managers and an extensive online survey. The findings revealed a strong consensus among managers regarding the pivotal role of digital communication and collaboration tools in maintaining the continuity of banking operations. These tools were found to facilitate seamless team communication and improve workflow coordination. However, the study also identified major challenges related to cybersecurity and data privacy, necessitating additional investments and heightened attention from senior management. From a leadership perspective, the study underscored a fundamental shift in traditional management practices, with digital leadership and virtual team management skills becoming critical for success in the new banking environment. Managers emphasized the urgent need to develop new performance evaluation methods and build trust in the absence of face-to-face interaction, while balancing flexibility and accountability in remote employee management. This study asserts that digital transformation in the banking sector is not merely about adopting new technologies but requires a comprehensive reevaluation of organizational culture and leadership models. It provides valuable insights for practitioners and decision-makers on the key factors ensuring the success of flexible work strategies in financial institutions. Additionally, it highlights the need for further research to keep pace with rapid technological advancements and their implications for the future of banking
