Abstract
Some embodiments are directed to a public-key encryption device () and a private-key decryption device (). The public-key encryption device is configured to compute a second public-key matrix (u), the second public-key matrix (u) having fewer matrix elements than the first public-key matrix (b) of the private-key decryption device. This reduces computation and bandwidth requirements at the side of the public-key encryption device.
