Automatic Privacy-Preserving Contact Tracing of Novel Coronavirus Infection by Cloud-Enabled WBAN using Blockchain
Anupam Pattanayak, Subhasish Dhal, Sourav Kanti Addya
Applications
Governments and policy makers are finding it difficult to curb the enormous spread of pandemic Covid-19 till the vaccine is invented and becomes available for use. When a person is detected to be infected with Novel coronavirus, the task of identifying the persons who have come across the victim in past fortnight is a challenging task. Identifying these contact persons manually is a hilarious task and often yields incomplete data. Some governments have used digital technology for contact...
Cryptanalysis of an Anonymous Authentication and Key Agreement Protocol for Secure Wireless Body Area Network
Mohammad Amin Rakeei, Farokhlagha Moazami
Cryptographic protocols
Recently, Kumar and Chand proposed an
anonymous authentication protocol for wireless body area
network. They claimed that their scheme meets major security
requirements and is able to resist known attacks. However, in this
paper we demonstrate that their scheme is prone to traceability
attack. Followed by this attack, an attacker can launch a man-in-the-middle attack and share a session key with the victim node,
and hence the scheme does not achieve secure authentication. Also,
we show that...
