ABSTRACT:
Recent advancement in technology in Healthcare Information Systems has led to a rise in cyber-attacks and data leakages at the data level. Existing data-level protection techniques that are developed to ensure data-level protection in Healthcare Information Systems lack integration of key security models such as Mandatory Access Controls, Role Based Access Controls and database security approaches in the design and development of data protection methods. In this study, science research methodology was used to design and develop a cryptographic algorithm with Base64 512 bits to enhance data protection at the data level. The algorithm was tested in a healthcare information system through experiments and simulations. The performance of the algorithm was tested to evaluate encryption and decryption process, strength on brute force attack and plain text vulnerability. The results of the observations showed that the developed algorithm with Base64, AES with fixed length of 512 bits, achieved optimal performance.

KEY WORDS: mandatory access controls, role based access controls, discretionary access controls, label based access controls, advanced encryption standard, electronic medical records.
