Optimized Signcryption Mechanisms with SIMON and Ring Signatures for Healthcare Data Security

With the rapid digitization in the health domain, needs arise to protect and safeguard sensitive information about patients in a secure, efficient, and prompt manner. This paper proposes an optimization mechanism for the protection of health data using techniques that apply ring signature-integrated lightweight block cipher SIMON. The SIMON encryption algorithm has wide-ranging speedy encryption that can be up to 25% faster than traditional block ciphers with a 30% saving in computational overheads and appropriate for resource-constrained environments. Ring signatures ensure there is anonymity of data yet authenticated in transmitting data. Therefore, this kind of proposed scheme will have higher integrity and confidentiality of data. The medical dataset was tested against the design; it even passed 98.5% attacks from cryptography. Encryption latency is still below 2 milliseconds. All the results ensure usability in modern systems of healthcare.
