One of the simplest and most often utilized forms of communication for sending and receiving messages is Short Message Services (SMS). Since SMS does not offer security measures by itself, security is a crucial consideration when using it to communicate sensitive data and information. Encryption has been found as a way to safeguard SMS messages both in transit and at rest, as sending SMS via a GSM network is not a secure method. For SMS and information security, numerous researchers have created and proposed a number of encryption techniques. Comparing the effectiveness of popular symmetric encryption methods on SMS security is the goal of this research. Three algorithms—AES, SALSA20, and fernet—are used in this research. The results demonstrate that, in terms of processing time, the SALSA 20 algorithm performs better than the other algorithms. This also brings up another point: AES runs faster than every other algorithm, with the exception of SALSA 20. Here, a third thing to note is that AES outperforms other FERNETs in terms of throughput and time consumption. Ultimately, despite using a small key size, it is discovered that FERNET performs poorly and has low throughput when compared to the other two algorithms. The results demonstrate that, in terms of processing time, the SALSA 20 algorithm performs better than the other algorithms. AES has an edge over other FERNET in terms of time consumption and throughput, as can be seen in this instance, as it requires less time than all algorithms except SALSA 20. Ultimately, despite using a small key size, it is discovered that FERNET performs poorly and has low throughput when compared to the other two algorithms.
