NETWORK SECURITY ENHANCEMENT FOR E-HEALTH SYSTEMS THROUGH DUAL ENCRYPTION TECHNIQUES

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.
