    Enhancing the Security of Electronic Medical Records Using Forward Secure Secret Key Encryption Scheme
    (2016) Kapis, Kosmas; Kambo, Edwin
    Electronic Medical Records (EMRs) pose a number of security challenges. Conventional cryptographic solutions have been used to protect the patients EMRs but with one major weakness; in an event where there is an exposure of a secret key, the secrecy of past and future encrypted data is void. This work concentrated on integrating the concept of forward secrecy in the protection of EMRs. In order to come up with the right integration, an experimental simulation has been carried out to evaluate the performance of forward secure and non-forward secure secret key encryption schemes. The study shows that only few cryptographic schemes that have implemented forward secrecy are used in the protection of EMRs, and very few of them use the forward secure secret key encryption scheme (FSSKES). The experiment also shows that the cost of running forward secure symmetric encryption is closely related to that of running non-forward secure symmetric encryption scheme (NFSSKES).
