The rapid evolution of technologies like Internet of Things (IoT) and Cloud computing which handle
big-scale data through the operations operate, store and manage. Besides, the technology facilitates
with operations related to safety and confidentiality concerns. Moreover, the increasingly accessible
cryptosystems offer the security concerns by IoT and cloud computing at several segments. In addition, the provision of third-party cloud process and analytics service contributors creates a privacy challenges to the consumer data. The current evolutions in the homomorphic encryption permits the computations on the data even when its encrypted. Therefore, a substantial research has been conducted on homomorphic encryption since few decades. However, the requirement of realtime implementation is essential for homomorphic encryption methods for achieving better improvements. Thus, the survey introduces the innumerable schemes for homomorphic encryption, advancements, and developments for decades, and its future progression for the implementation in real-time scenario.
