1. A method for lightweight post-quantum authentication comprising:
receiving a message at a signer device;
generating a security parameter;
generating a number of seeds associated with the signer device, the number of seeds being at least two seeds and corresponding in number to a set of at least two servers, based on the security parameter;
transmitting the at least two seeds to each server of the at least two servers;
determining via the signer device a private key based on the security parameter or the at least two seeds, the private key corresponding to a public key generated in a distributed manner by the at least two servers based on the at least two seeds; and
generating, via the signer device, on the message, a signature based on the private key.
