Major security requirements for securing communication between WBAN and external users.
Security requirements
Description
Data confidentiality, authenticity, integrity, and availability
Data must be transmitted in encrypted frames and measures have to be provided against message modification, privacy disclosure, and Dos attack.
Access control
Besides identifying attackers, differences in professional knowledge among the patient, doctor, and nurses may have influence on the patients treatment; thus fine-grained access control policy has to be enforced to define the users access privileges.
Nonrepudiation
The origin of data (i.e., patient or medical personnel) cannot be denied for having sent or received the messages.
