Table 13: Comparative Analysis of SPAC for HMCC, AES, and DES. suitable for lightweight cryptography on resource-constrained devices. The searchable encryption-based technique employed is capable of direct access to information on the cloud irrespective of the size of data stored on the cloud, and also conserves space by avoiding data redundancy in the cloud in an attempt to use FHE. The scheme also reduces the complexity involved in computation in FHE implementation in [59]. It can, therefore, be said that the proposed IoMT-based model is provably secure and preserves the privacy of critical user data. The manuscript was written through the contributions of all authors.
