This thesis introduces the digital signature technology involved in PKI. First, we introduces two important concepts of public key cryptosystem and trapdoor function related to digital signature. Then we explains the conditions that the digital signature scheme should meet, gives the basic idea and mathematical description of the digital signature scheme, and analyzes the two classic digital signature algorithms, RSA and DSA, and introduces the methods for these two digital signature algorithms. Finally, we use some attacks to further prove the universality of the mathematical description of digital signature schemes, and summarize several commonly used digital signature schemes.
