Mobile health (m-Health) system architectures are typically based on mobile and wireless communications, and use mobile devices with data exchange supported by Web services (WS). Although m-Health systems offer mobility as a potential and precious resource they also present several challenged issues and constraints, such as, battery and storage capacity, broadcast constraints, interferences, disconnections, noises, limited bandwidths, and network delays. Furthermore, constant mobility and often-required Internet connectivity also exposes and compromises the privacy and confidentiality of the m-Health system information. This paper proposes a novel data encryption solution for mobile health systems, considering a novel and early-proposed cooperation strategy. This encryption solution, tries to guarantee the best confidentiality, integrity, and authenticity of m-Health systems users data. The paper also presents a performance evaluation study comparing the performance an m-Health application with and without the DE4MHA.
