Abstract
In a general aspect, a parameter is refreshed in a lattice-based cryptography system. In some aspects, a first value of a public parameter is obtained. The first value of the public parameter may have been previously used in an execution of a lattice-based cryptography protocol. A second value of the public parameter is generated based on the first value of the public parameter and random information. The second value of the public parameter is used in an execution of the lattice-based cryptography protocol.
