According to the 2013 record, about 80,000,000,000 mobile apps have been downloaded and the number is expected to double in the next four years.

Such a large number of apps are competing for the user's energy, which is bound to lead to a decrease in user time for each app. This is a big problem for mobile apps that require new users to register.

In order to write, read, and modify the code easily, it is best to reduce the number of different objects, and can be a large number of widely used objects uniformly expressed
^ 103 mod 143 = 85
After receiving the digital signature of Party B, Party A uses the Public Key (n, e) = (143,7) of Party B to calculate the code representing the identity of Party B:
C = m ^ e mod n = 85 ^ 7 mod 143 = 123
The sender of the verified information is B. Because only Party B has the private key (n, d) to calculate the encoding 123 representing its own identity. Without knowing the private key (n, d) of Party B, No one will calculate the signature 85 to impersonate Party B. H
