No proof of security for the Schnorr signature scheme is known under standard cryptographic assumptions.

Schnorr groups are useful in discrete log based cryptosystems including Schnorr signatures and DSA.

One round: Alice selects and sends out together with a zero-knowledge proof (using for example Schnorr signature) for the proof of the exponent .

Claus P. Schnorr provided an attack on blind Schnorr signatures schemes, which were argued to be secure by Pointcheval and Stern.

In cryptography, a Schnorr signature is a digital signature produced by the Schnorr signature algorithm.

Some widely known cryptosystems include RSA encryption, Schnorr signature, El-Gamal encryption, PGP, etc.

The company published the standards to promote the use of the cryptography techniques to which they had patents, such as the RSA algorithm, the Schnorr signature algorithm and several others.
