Abstract
Cloud computing is a technology that holds great promise and has potential to revolutionize
the healthcare sector. Many security and privacy issues are brought up by the cloud’s centralization of data for both patients and healthcare professionals. There is a need for maintaining
secrecy in communication in exchanging medical data between the sender and the receiver,
which can be done by cryptography. This article presents a cryptographic algorithm (encryption
and decryption) to have a secure communication of digital health care confidential data using
DNA cryptography and Huffman coding. The interesting property is the cipher size obtainedfrom
our algorithm is equal to the size of the cipher obtainedfrom the character set of given data. Security analysis is provided to show the security of data when stored and transmitted to the cloud.
The cryptographic requirements, key space analysis, key and plain text sensitivity, sensitive score
analysis, sensitivity and specificity, optimal threshold, randomness analysis, uniqueness of implementation, entropies of binary bits, DNA bases, DNA bases with Huffman code, Huffman encoded binary bits and cloud service provider’s risk are analyzed. The method proposed is compared with other cryptographic methods and results that it is more secure and stronger than other methods.
