  • Publication number: 20240250815
    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.

  • Publication number: 20220056684
    Abstract: A regenerative stormwater conveyance (RSC) system for treating and dispersing stormwater runoff is disclosed which includes an upstream entry point where water enters the system and an entry pool downstream from the entry point that collects water from the entry point. The RSC system includes one or more shallow aquatic beds that receive water from the entry pool in a serial manner and each of which includes a filtration structure for filtering water from the aquatic bed. Riffle weir grade control structures are positioned between the aquatic beds and transition water overflowing from each upstream aquatic bed to a downstream aquatic bed. Accordingly, collected stormwater runoff traverses the series of aquatic beds and riffle weir grading structures and is treated and safely detained, thus, conveying stormwater to groundwater through infiltration.

  • Publication number: 20220025632
    Abstract: A system and method for restoring wetland habitats and providing a platform on which indigenous and transplanted plant species can thrive. Water from a source, such as, stormwater run-off is captured and filtered through a combination of sand berms and riffle weirs to a series of aquatic beds, thus creating nutrient-rich environment.
