Advancing medical image security: a hybrid DNA-AES based cryptosystem
Abstract
In today’s technological age, it is simple to obtain someone’s personal information
via data transmission, especially for those who don’t use sufficient data security
throughout the process. Data breaches are now a significant security concern since
private information is constantly transmitted through the internet around the world.
Healthcare organizations experience data breaches and attacks more frequently than
businesses in other sectors. Therefore, medical information needs to be transferred
securely during the transmission of medical data to protect patients’ sensitive details.
Cryptography defines a secure transmission and communication process that
results from mathematical ideas and rule-based calculation algorithms. This is how
cryptography provides an efficient way for transmitting data in a secure manner
that can protect it from third parties for medical data transmission. In the field
of cryptography, DNA cryptography is a more secure technique because it uses the
biological structure of DNA. It is a technique for hiding data that converts the alphabet
into various combinations using the four bases of human deoxyribonucleic
acid. Although there are many operations in DNA cryptography, the XOR operation
is more versatile. DNA XOR techniques have configurations that are responsive
and distinctive, in contrast to the current binary representation of 0s and 1s. The
suggested encryption and decryption techniques for protecting information and storage
in the sequences of DNA are particularly safe since the sequences of genes are
used as the key parameters for the DNA XOR procedure. Additionally, to further
strengthen security and resolve possible drawbacks of the conventional DNA-based
method, the AES-256-GCM algorithm has been integrated. Comprehensive performance
testing is conducted to assess the hybrid DNA-AES approach’s reliability
and efficiency. This research proposes a novel approach for securing medical data
transmission using the DNA-AES cryptosystem.
