Abstract

Systems and methods are provided for implementing encryption of data-in-motion and/or otherwise stored data using a key server and a secure enclave of a Network Interface Card (NIC). The NIC acts as a passthrough between the client device and the shared infrastructure of the supercomputer system to help ensure data security in a massively scaled and distributed system. For example, in response to an enrollment process that stores a decrypted key in the secure enclave of a NIC, the NIC can receive a data packet from a client device. The NIC can transmit a key request to a key server that includes an encrypted key corresponding to the decrypted key. The key server can look up the previously stored private/public key pair to authenticate the NIC. The key server can provide private/public key pair to the NIC to allow the NIC to later encrypt data-in-motion.
