Enhanced mobile app security for healthcare applications

As the number of mobile device usage continues to rise, the security of mobile apps is becoming an increasingly pressing concern as they have become an integral part of our daily lives. Mobile application, particularly those handling sensitive data like healthcare information, face increasing threats from malicious actors seeking unauthorized access. This paper explores the integration of Advanced Encryption Standard (AES) for data encryption and Elliptic Curve Cryptography (ECC) for key encryption in a healthcare application. The paper demonstrates how AES-ECC encryption can be integrated into the core of the application, creating a fortress of confidentiality and integrity. AES encryption safeguards healthcare data from unauthorized access, ensuring its confidentiality and compliance with regulations like HIPAA while ECC's efficient key management allows for shorter encryption keys, enhancing app performance in mobile app environments with limited storage and computational power. The performance of the AES-ECC setup is also tested, comparing power consumption and CPU time against scenarios where only AES encryption is used. The findings contribute to the advancement of mobile app security practices and offer insights and guidelines for developers to safeguard sensitive data against evolving cyber threats.
