Abstract: WBNs are the sensors that are used for extracting patient health related information. But due to less computational power and limited storage of these devices, these devices are amalgamated with cloud for storage that further helps in real time monitoring of the patient’s health. This in turn helps in providing early diagnosis of the patient and saves the patient’s life. This transmission of sensitive data to cloud faces various security challenges. This research focuses on designing and implementation of Certificateless Secured Signature Scheme (CSSS) which provides a great level of security to the sensitive data in transit. Signcryption scheme is implemented which performs encryption and signing in a single logical step. As small key size in ECC provides a high level of security so keys are generated using ECC and data is encrypted using AES algorithm. Our secured scheme is proficient to achieve various security parameters such as confidentiality, authentication, integrity, unforgeability and forward secrecy and non-repudiation. Our scheme improves computational cost and provides a high level of security.
