Abstract EN
Current trends of mobile technology have seen a tremendous growth in its application in smart healthcare.
This has resulted in the adoption and implementation of mobile health (m-health) systems by providing health assistance to the aging population.
Despite its advantageous benefits, its computational complexities cannot be overlooked.
M-health devices are portable processing tiny equipment with limited computational capabilities thereby making them complex for the implementation of public key cryptosystems.
In spite of this, an Offline-Online signature scheme called the MHCOOS has been proposed to solve the difficulties in the computational ability.
The scheme enjoys the following benefits by splitting the signing part into both offline and online phases.
The offline phase performs heavy computations when a message is absent, whereas lighter computations are performed at the online stage when a message is present.
Secondly, the online computations are extremely fast due to the already computed offline signature value and lighter pairings involved.
Our performance analysis demonstrates how the proposed scheme outperforms other schemes.
Finally, the hardness of the scheme is proven under the Bilinear Diffie–Hellman (BDH) and Computational Diffie–Hellman (CDH) problem in the random oracle model.
