US Patent 11934323 Diversifying a base symmetric key based on a public key

A symmetric key that is stored at a device may be received. A public key from a remote entity may also be received at the device. Furthermore, a derived key may be generated based on a one way function between the symmetric key that is stored at the device and the public key that is received from the remote entity. The derived key may be encrypted with the public key and transmitted to the remote entity. The encryption of the derived key with the public key may provide secure transmission of the derived key to an authorized remote entity with a private key that may be used to decrypt the encrypted derived key.
