The paper presents the secure delivery of firmware updates to Internet of Things (IoT) devices. Additionally, it deals with the design of a safe and secure bootloader for an Ultra High Frequency Radiofrequency Identification (UHF RFID) reader. A software implementation of a secure firmware update solution is performed. The results show the implementation of the Advanced Encryption Standard (AES) encryption into existing IoT devices, e.g. UHF RFID reader, requires at least 49.7 kB of flash
