Abstract
Homomorphic encryption (HE) is gradually gaining popularity. It ensures computation on encrypted data without compromising confidentiality. Despite its potential, the implementation of HE faces challenges. Notably among them is the lack of uniformity and standardization.
The purpose of this study is to develop a standardized model for implementing HE in various application areas. A star model was developed with evaluation at the centre. With this structure, activity at each stage is evaluated before moving to the next stage.
The model was tested with the West African Examination Council (WAEC) and the Ghana Education Service (GES) School Placement System. Data from WAEC was encrypted homomorphically and transmitted to GES. The GES system then used the encrypted data to place candidates into various Senior High and Technical Schools. This ensured computation on encrypted data whilst maintaining confidentiality. The result of the study showed that the use of the model ensured standardization. The proposed model should, therefore, be used when implementing HE in various application areas.
