Short Message Service (SMS) architecture It can be seen from Figure 1 that a text message must go through various destinations before it reaches its target recipient. First, a cellular tower called BTS will receive the message and forward it to Base Station Controller (BSC). In turn, BSC will forward the messages through Mobile Switching Center (MSC) where it is passed to Short Message Service Center (SMSC). SMSC has the responsibility of checking whether the recipeint has cellular signal or not. This can be done by using Home Location Register (HLR) protocol. In the case the recipient mobile phone is out of reach, SMSC will keep the message indefinitely until the network has been restored. Finally, SMSC will forward the messages to the Mobile Switching Center (MSC) of the designated recipient, and the above process is repeated in reverse order before the text message reaches the recipient.

Despite the popularity of social media and Internet-based messaging services, Short Message Service (SMS) is still widely used by a lot of people worldwide. However, in this modern era, Short Message Service (SMS) is not a secure way of sending and receive text messages. Anyone with the right privilleges can easily read all the messages sent using...

... a combination with AES will result in much better security while still not being too resource heavy and maintaining a reasonable process time. Figure 1 below describes the Short Message Service (SMS) architecture commonly used today. In turn, BSC will forward the messages through Mobile Switching Center (MSC) where it is passed to Short Message Service Center (SMSC). ...

Cryptographic algorithms are used to ensure confidentiality, integrity and authenticity of data in information systems. One of the important areas of modern cryptography is that of symmetric key ciphers. They convert the input plaintext into ciphertext, representing it as a random sequence of characters. S-boxes are designed to complicate the input...
