Counter-based security mechanism between mobile application and API services

This study aims to develop an innovative security mechanism called 'cTrust', focusing on the widespread use of mobile devices and the security challenges it brings, to enhance secure communication between mobile applications and Application Programming Interface (API) services. The counter-based security mechanism provides an effective strategy for mobile applications to communicate securely with API services. The developed mechanism initiates authentication processes for mobile applications and generates a one-time token (cToken), offering a continuously changing authentication process. The counter information used in the authentication process is encrypted with a secret key and decrypted only by the API service, thereby enhancing the effectiveness of the one-time authentication mechanism. This strategy stands out as an effective solution to enhance the security of API services. The study aims to provide a secure interaction between mobile applications and API services by offering an alternative perspective to existing security approaches. The counter mechanism adds a unique security layer in addition to traditional security methods, creating a more resilient structure against attacks. In this context, it aims to enhance security between mobile applications and API services and provide an alternative security mechanism in digital communication. Consequently, the security of mobile applications and API services holds critical importance today. The cTrust counter-based security mechanism offers an effective solution to enhance security and holds the potential to comply with industry security standards. While aiming to enhance security between mobile applications and API services, this study also aims to provide an alternative and independent security strategy.
