  • Abstract:

Information security encompasses the protection of digital privacy strategies which
are used to stop illegal access to information, records, and computing devices. This paper applied an
algorithm based on Caesar Cipher and DNA Sequences. In the proposed system, a method of
generating DNA Sequences with keys to secure data with encryption and decryption methods were
implemented. The algorithm utilized large hidden keys values during the encryption process for
shifting in the Caesar Cipher algorithm and DNA sequencing applied the uniqueness of DNA
characteristics. The system achieved an effective level of security for data compared to existing algorithms
as the Cryptanalysis of the Caesar Cipher decrypted texts with Chi-Squared values around 150. The
enhanced Caesar Cipher with DNA Sequences decrypted texts with Chi-Squared values far above
150 which showed that the system is less vulnerable to hackers and unauthorized access.
