Abstract: Inventive aspects include a device including storage media. The device includes a PMU, and a controller communicatively coupled to the PMU. The PMU determines that an operating power of the device exceeds a threshold, and transmits a signal to the controller to trigger a power reduction operation. The controller throttles one or more operations until the operating power goes below the threshold. Some embodiments include a method for controlling performance of a storage device. The method includes measuring, by a PMU, a power consumption associated with a storage device. The method includes determining, by the PMU, whether the power consumption is greater than a threshold. In response, the method may include setting a performance throttle. The method may include determining, by the PMU, whether the power consumption is less than the threshold. In response, the method may include releasing the performance throttle.

Abstract: A method for managing security keys for an I/O device may include loading a first security key from a primary memory to a security engine, performing a first data transfer operation between a host and the I/O device using the first security key with the security engine, loading a second security key from a secondary memory to the security engine, and performing a second data transfer operation between the host and the I/O device using the second security key with the security engine. The method may further include storing the first security key in the primary memory based on a frequency of use of the first security key. The frequency of use of the first security key may be determined by a pattern of transfers between the host and the I/O device.

Abstract: Various aspects include a continuous authentication system for a storage system. The continuous authentication system includes a host having an encryption unit. The continuous authentication system includes a storage device having a decryption unit. The continuous authentication system includes a first physical connection between the host and the storage device. The first physical connection may be configured to transfer I/Os. The continuous authentication system may include a second physical connection between the host and the storage device. The encryption unit may be configured to encrypt a continuous authentication signal. The host may be configured to transmit the continuous authentication signal through the second physical connection. The storage device may be configured to receive the continuous authentication signal through the second physical connection. The decryption unit may be configured to decrypt the continuous authentication signal. When the second physical connection is tampered with, the storage device may stop processing the I/Os.
