EHC-BGV hybrid homomorphic encryption algorithmic sequences for processing authenticated role based secure keys

The algorithm is designed to show the step-by-step procedure of the proposed methodology which experimented with four test cases: first one initiated with creation of multiple tenants in cloud architecture; second one with integration of uploading a file on cloud server on real-time; third one initiated end user request for accessing a file and last one processed self-key mutation in case of an attack. It integrated with key mapping parity rules and 14 multi-authentications, dependable, and non-dependable parameters which tuned with initiated variables based parameters which initiated and implemented at sender and receiver side for restricting unauthorized access. The methodology tested for 161 end-users, 10 multi-tenants, 8 head-tenants and 3 enterprise levels, and achieved 95 percentages of data transmission and access control rate.
