Abstract: Computer science and telecommunications technologies have been experiencing rapid advancements in recent years to protect sensitive data or information from potential harm, misuse, or destruction. By enhancing data security through various methodologies and algorithms, data can be better protected against attacks that may compromise its confidentiality, particularly in the case of text messages. Linear cipher is one of the earliest forms of cryptographic systems which operates by shifting letters that may not provide the highest level of security but adds a layer of complexity to the initial encryption process. Rivest-Shamir-Adleman algorithm represents a more advanced and rigorous approach to encryption that resistant to more sophisticated attacks. The Rivest-Shamir-Adleman algorithm utilizes the mathematical properties of large prime numbers to establish a secure communication channel. The combination of both algorithms or hybrid algorithms employed for data security, the security of text messages is significantly improved, ensuring the confidentiality of the text messages during its transmission. Hence, this research proposes two types of hybrid algorithms, namely Gradatim LRSA and Optimized LRSA, which ensure the confidentiality of the text message using encryption and decryption processes. The results also show that the Optimized LRSA performs with less computation compared to the Gradatim LRSA.

Keywords: Confidentiality; data encryption; hybrid encryption; linear cipher; RSA algorithm; Gradatim LRSA; Optimized LRSA
