AI summary

Disclosed is a commutative encryption and watermarking method utilizing deoxyribonucleic acid (DNA) base complementary dynamic encryption for a high-definition map. According to the method, on the basis of a DNA base pair complementary principle and data features of the high-definition map in the OpenDRIVE format, a commutative encryption and watermarking algorithm based on base pair complementary dynamic encryption for a high-definition map. In an encryption method, cubic curve parameters configured to denote elevation elements and lane widths in data are encrypted through a nucleotide base complementary principle in DNA. In a watermarking method, a number of elevation elements and lanes is not influenced by encryption, and the invariant feature is used to generate a zero-watermark. Interchangeability of encryption and watermarking is obtained.
