Abstract: A method to exchange and manage a key is provided. The method includes receiving, at a computational storage device (CSD), a user certificate (CAuser) that is generated based on a public key of a user (PUuser);extracting, at the CSD, the PUuser using a public key of the certificate authority (PUca); generating, at the CSD, an encryption program key; encrypting, at the CSD, the encryption program key using the PUuser to generate an encrypted encryption program key; and storing, at the CSD, the encrypted encryption program key.
