Abstract

Aspects of the present disclosure relate to techniques for deriving cryptographic keys. Embodiments include using a key encapsulation mechanism to encrypt various data items transferred between a first remote server and a client device during a key derivation process. In some embodiments, the encrypted data items include a blinding value and a client key. Embodiments further include using a hybrid post-quantum key exchange technique to securely store and transfer keys used by the remote servers as part of the key derivation process.
