Abstract

A method for publicly verifiable symmetric cryptography is disclosed. The method includes: obtaining an initial encrypted key and a homomorphic public key; obtaining a first message and an initial signature; calculating an initial hashed value of the first message; setting a cryptographic function of the initial hashed value of the first message and an initial private key; generating an evaluated value based on the cryptographic function, the homomorphic public key, the initial encrypted key, and the initial hashed value of the first message; and transmitting, at the verifier, a verification result based on a hashed value of the initial signature and the evaluated value. Other aspects, embodiments, and features are also claimed and described.
