Security in Next Generation Mobile Payment Systems: A Comprehensive Survey
It addresses security concerns in mobile payment systems for users and developers, but it is incremental as it is a survey without new experimental results.
This paper surveys security models for mobile payment systems, exploring various technologies, comparisons, and mechanisms like encryption and authentication, while also discussing current challenges and future directions.
Cash payment is still king in several markets, accounting for more than 90\ of the payments in almost all the developing countries. The usage of mobile phones is pretty ordinary in this present era. Mobile phones have become an inseparable friend for many users, serving much more than just communication tools. Every subsequent person is heavily relying on them due to multifaceted usage and affordability. Every person wants to manage his/her daily transactions and related issues by using his/her mobile phone. With the rise and advancements of mobile-specific security, threats are evolving as well. In this paper, we provide a survey of various security models for mobile phones. We explore multiple proposed models of the mobile payment system (MPS), their technologies and comparisons, payment methods, different security mechanisms involved in MPS, and provide analysis of the encryption technologies, authentication methods, and firewall in MPS. We also present current challenges and future directions of mobile phone security.
