a new ciphertext corresponding to a result of some operation on the plaintexts can be generated without knowledge of the secret key. We focus on addition as the operation. That is, by using two ciphertexts\(c_1 = \mathsf {Enc}(m
Akbal, Barua, Dogan, Tuncer, and Acharya (2022) introduced a data encryption standard cipher model - DesPatNet25 which utilized a novel hand-modeled automated system and was evaluated on a public construction site monitoring (CSM) sound dataset. An accurate fire learning model was proposed by ...
