The privacy and security issues of information message dissemination have been well researched in typical wearable sensores. However, cloud computing paradigm is merely utilized for secure information message dissemination over wearable sensors. Sharing encrypted data with different users via public cloud storage is an important functionality. Therefore, many researchers proposed new cloud based user authentication scheme for secure authentication of medical data. Newly A.K.Das et al proposed a new user authentication scheme in which a legal user registered at the BRC will be able to mutually authenticate with an accessible wearable sensor node with the help of the CoTC. Though A.K.Das et al scheme counterattacks key cryptographic attacks, on subsequent in-depth analysis, we validate that their scheme has security downsides such as failure to counterattack ‘privileged insider attack’, which int
