With the development of Internet of Things technology, the lightweight cryptographic algorithm has become a research hot topic in recent years. Power analysis attack is the most security threat to the cryptographic chip. It has theoretical and practical value from the system security problem research of lightweight cryptographic related structure and evaluation.The novel lightweight block cryptographic algorithm with its own ability of resisting power analysis attack ability is proposed. In order to achieve this goal, the following three sub goals are needed to be researched. First of all, we ...
