Abstract: A method includes receiving, at a controller of a computational storage (CS) device, a request to allocate computational storage to an application of a host device. The request includes a resource set ID associated with the application. The method further includes identifying a memory range within a memory region of the CS device. The method further includes storing, in a data structure associated with the resource set ID, an association between a memory range identifier (ID) of the memory range, the memory region, and an offset within the memory region. The method further includes sending the memory range ID to the host device.

Abstract: Systems and methods for parameter management. In some embodiments, a method includes: receiving, by a computational storage device, a program, and a first parameter type descriptor; receiving, by the computational storage device, a program execute instruction including a second parameter type descriptor; determining, by the computational storage device, that the second parameter type descriptor matches the first parameter type descriptor; and executing, by the computational storage device, the program.

Abstract: A computational storage device (CSD) and a method thereof are provided. The method includes receiving, from a user device, a computational storage (CS) request, identifying the CS request as an attack, comparing a total attack value of the user device to a threshold, wherein the total attack value is based on a number of attacks received from the user device, and identifying the user device as an attacker based on the comparison.

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.

Abstract: A Key-Value (KV) storage device is disclosed. The KV storage device may include storage for objects, each object including data associated with a key. A host interface layer may receive requests to read data associated with a key from the storage, to write data associated with a key to the storage, and a boot request to get boot data from the storage. A boot request processor may process the boot request using the storage.
