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.
