资源受限的计算设备（诸如射频识别（RFID）标签、传感器节点、工业控制器和智能卡）的利用如今非常普遍。从台式机到小型设备的转变使生活变得稳定，并带来了广泛的安全和隐私问题。有加密算法来确保数据和用户的安全性和隐私性。大多数情况下，任何加密算法的安全性都取决于轮函数中使用的替换盒。本文提出了一种新的分组密码SAT_Jo，它适用于物联网（IoT）中基于标签的应用。本文利用24阶伽罗瓦域计算了一个4×4的S盒。置换被解释为从集合到自身的双射映射。子密钥计算是在每个阶段都有变化的情况下进行的。加密算法用数学图解说明。
The utilization of resource constrained computing devices such as Radio-Frequency IDentification (RFID) tags, sensor nodes, industrial controllers and smart cards is very common today. The move from desktop computers to small devices made life stability to mobility and brings a wide range of security and privacy concerns. There come the cryptographic algorithms to ensure the security and privacy of the data and the users. Mostly, security of any cryptographic algorithms depends on the substitution boxes that are used in the round function. This paper proposes a new block cipher, SAT_Jo, which is suitable to the tag based applications of the Internet of Things (IoT). This paper computes a 4×4 S-box by the Galois field of order 24. Permutation is explained as a bijective map from the set to itself. Sub key computation is carried out with a change in each phase. The encryption algorithm is explained with a mathematical illustration.
