NETWORK SECURITY ENHANCEMENT FOR E-HEALTH SYSTEMS THROUGH DUAL ENCRYPTION TECHNIQUES
Main Article Content
Abstract
The increased use of e-health systems requires better methods for keeping patients’ sensitive information private, complete, and available.In this study, we propose the use of a dual encryption model which encompasses the RC4 stream cipher and the CBC-Twofish block cipher for providing end-to-end security in electronic health record (EHR) real-time transmissions as well as their storage.The encryption of RC4 is fast because it is also known for being extremely light in terms of computation. Therefore, this encryption uses the fastest means possible and still leaves room open if there are any other kinds of problems arising in connection with information transmissions.Physiological data is encrypted with a lightweight, high-speed cipher called RC4, which ensures that there is little delay when sending it over a communication link and the like.This cross-interference is important for additional protection measures because it hampers the smooth flow of information within block units. hence, It enhances overall system security,The proposed system has undergone evaluation through the NIST suite analysis tool to establish randomness as well as their performance measurements like encryption speed vis-à-vis scalability, among others.It is evident from the results that this framework has superior cryptographic strength and is more efficient than the usual AES or DES algorithmic encryption methods.The dual encryption approach guarantees end-to-end data confidentiality without Compromising security, Compromising the required performance specifications of real-time healthcare systems.This method can be seamlessly integrated into contemporary e-health infrastructures; hence providing effective means through which confidentiality of patient records may be achieved even in cases where medical facilities are located far from each other.
