The enormous developments in the Internet and communications applications present new security challenges, such as sensitive data collection of IoT devices. Cipher algorithms play a key role in IoT applications, countless cryptosystems are presented for securing such applications. Various challenges were intensely presented due to the vast increase in the developments of IoT applications and the requirements of the cipher algorithms which are considered the main challenges for adapting lightweight cryptosystems. Thus, in this study, different cipher algorithms are reviewed and analyzed based on lightweight cryptosystems. Moreover, various features are examined and discussed through the most common cipher algorithms for designing cipher algorithms to be efficient in IoT applications. The result showed the major challenges and factors that should be undertaken when designing cryptosystems of IoT applications. The challenges are experimented with parameters such as key size, computational cost, time, etc. This work would be referenced for developing an efficient cipher algorithm for IoT applications which presents the main factors and challenges that should be considered when designing such cryptosystems.
