An Analysis of Homomorphic Encryption in Latest Technologies

Karan Chawla

Abstract: A particular time-consuming evaluation algorithm is supported by homomorphic encryption, a type of encryption. This approach enables specific operations to be performed on the ciphertext without the need for a secret key. This review article looks at the most recent technologies that can safeguard data via homomorphic encryption such as Vehicular Ad Hoc Networks, Internet of Things for Mobile and Internet of Things for Cloud Computing and Internet of Medical Things. A safe computing solution for vehicle data has been devised employing partial homomorphic encryption, or Fully Homomorphic Encryption (FHE), for the majority of protocols. Only homomorphic addition or homomorphic multiplication is supported by partial homomorphic encryption, and implementing these operations requires additional rounds of interaction. This is a concern because the unusually long execution time of homomorphic multiplication makes it difficult to maintain real-time communication on VANETs. Use of Partial or Full homomorphic encryption for real-time communication in VANETs might be a good option since it ensures both addition and multiplication to take place an infinite number of times. It is crucial to stress that while permitting third-party cloud computations, data privacy are preserved. However HE comes at a higher expense in terms of processing because of its inherent complexity. Data traffic increases as ciphertext size increases, increasing the cost of transmission in terms of energy utilization and fees per transmitted byte. Activities in IoMT must be performed directly on network nodes that healthcare services manage and that are situated closer to the device layer in order to reduce latency. Similar research is needed to reduce the distance between the healthcare services and the device layer in order to reduce latency. The current study does not address the issue of a secure communication link between the device and base station for the Internet of Medical Things.
