Security in telemedicine has been of great interest in recent years due to the personal and
confidential information that is used, since it is sent or stored through insecure channels,
which generates a security problem such in telemetry, where biomedical signals (ECG, EEG,
SpO2) are used for diagnosis of diseases. In this work, a chaos-based cryptographic
algorithm is proposed using two-dimensional Badola map implemented in an embedded
system based on a 32-bit microcontroller to provide confidentiality of biomedical signals …
