The security of 5G networks includes a combination of encryption, authentication and access control mechanisms to protect data and ensure the integrity and confidentiality of communication. Encryption, such as AES, plays an important role in protecting the privacy and integrity of data transmitted over 5G networks. The purpose of the paper is to design a custom encryption algorithm for educational purposes and to present a more detailed implementation that follows the AES specification exactly. The design of a custom AES encryption algorithm with implementation of AES-128 encryption in Cipher Block Chaining (CBC) mode and key expansion can be considered as the main contribution and achieved result. For the purpose of the task, we used the pycryptodome library and created a Python script for AES-128 encryption.
