Abstract
In the context of the rapid growth of security threats to mobile devices, information protection becomes a critically important task. The article is an overview of modern advanced technologies used for the development of secure mobile communication devices and crypto-smartphones. A bibliometric analysis was conducted using the Bibliometrix tool. The main principles for organizing secure communication have been classified. Innovative approaches are being considered to ensure data integrity and confidentiality. The latest achievements in the field of mobile communication security are also being analyzed. During the research, an informational and patent search for inventions in the field of mobile communication protection was conducted, and a comparative analysis of the advantages and limitations was carried out. The analysis conducted showed that some decisions create a false sense of security, as they propose the adoption of unconventional methods that do not align with well-established and widely accepted safety recommendations. The article describes the main crypto smartphones, each possessing unique characteristics and designed for specific user needs based on their functional capabilities. The provided examples of successful implementations and research demonstrate the significance of innovative solutions for enhancing the security of mobile communications and protecting personal data in the context of the modern digital world.
