Digital Signature Algorithm (DSA) is a variant of the Schnorr and ElGamal signature algorithm, which was used as a DSS (DigitalSignature Standard) by the United States NIST. The following parameters are applied in the algorithm: p:l bits are primes. L is a multiple of 64, the range is 512 to 1024;q:p-1 of the 160bits factor; g:g = h^ ((p-1)/q) mod p,h satisfies h < p ...

Section III encryption algorithm 1, RSA algorithm It is the first algorithm that can be used both for data encryption and digital signature. It is easy to understand and operate, and very popular. The name of the algorithm is named after the inventor: Ron Rivest, Adi Shamir and Leonard Adleman. But the security of RSA has not been proved theoretically. It has undergone various attacks and has not yet been completely breached. RSA algorithm: First, find out three number, p,q,r, where P,q is two different prime numbers, R is with (p-1) (q-...
