Abstract
Embodiments of the present disclosure may include a key generation device of a lattice-based public key cryptosystem. In some embodiments, the key generation device may include a communication unit, a storage unit, and a processor that may be configured to control the key generation device to perform operations. In some embodiments, the operations may include generating a public key by using a public key polynomial, where the public key polynomial may belong to a first polynomial ring. In some embodiments, the operations may additionally include generating a secret key that may correspond to the public key. In some embodiments, the secret key may be generated by using a secret key polynomial that may belong to a second polynomial ring. In some embodiments, the operations may additionally include storing the public key and the secret key.
