Abstract: An encryption method is provided to protect information efficiently and safely in an application environment requiring ultra lightweight and low power consumption by using very simple structure like XOR, addition, and cyclic transition. A whitening key and a sub key are generated by receiving a master key. A plain sentence is received and converted into an initial round function value(120) by using the whitening key. A plurality of round functions are processed by using the initial round function value and the sub key. An encrypted sentence is generated by using the round function value, which is generated by processing the round functions, and the whitening key. The master key comprises eight sub master keys, the length of the sub master key is eight bits, and the length of the master key is 16 bits. The master key is formed by connecting the sub master keys.
Abstract translation: 通过使用XOR，加法和循环转换等非常简单的结构，提供了一种加密方法，可在需要超轻量级和低功耗的应用环境中高效安全地保护信息。 通过接收主密钥来生成白化密钥和副密钥。 通过使用白化密钥接收纯语句并将其转换为初始轮函数值（120）。 通过使用初始轮函数值和子密钥来处理多个循环函数。 加密句子通过使用通过处理圆函数而生成的舍入函数值和白化密钥来生成。 主密钥包括8个子主密钥，子主密钥的长度为8位，主密钥的长度为16位。 主密钥由连接子主密钥形成。
