Ensuring data security and integrity is vital for achieving optimal protection and performance in modern cyber-physical systems (CPS). Authenticated encryption with associated data (AEAD) provides an efficient and secure method for data encryption, guaranteeing both confidentiality and authenticity. TinyJambu cipher is a lightweight authenticated encryption algorithm tailored for resource-constrained environments such as Internet of Things (IoT) devices, radio frequency identification (RFID) tags, and embedded systems. This paper presents optimised architectures of TinyJambu cipher, focusing on round-based and area-optimised implementations to enhance performance and efficiency on various field programmable gate array (FPGA) platforms. These designs achieve a balance between high throughput and minimal resource usage. Comparative analysis with other AEAD ciphers highlights the superior efficiency of TinyJambu cipher and performance, confirming its suitability for modern lightweight cryptographic applications.
