AI Technical Summary
Existing encryption algorithms such as AES are complex to manage and transmit in IoT terminal devices. The position substitution rule is not easy to describe and requires multiple keys. Iterative encryption is complex and difficult to apply on multi-user platforms.
Information position replacement is performed using a sequence based on an exponential integer field. An exponential integer field is generated by sharing a pair of positive integers, and the information is divided into a circular translation sequence. Local or global position replacement is then performed. The circular translation sequence is used to perform one-to-one correspondence and position replacement to form encrypted transmission.
It achieves low-complexity information location replacement, enhances password security, reduces key management complexity, is suitable for multi-user platforms, and provides greater password space and flexibility.
