Samsung patents storage setup that processes encrypted data on a separate chip
Samsung describes a storage system where a main drive encrypts data before sending it to a separate reconfigurable logic chip. This second chip processes the data while it remains encrypted and sends the results back to the storage drive.
In the filing’s own words
A storage device set includes a storage device configured to communicate with a host, the storage device including a controller configured to generate encrypted input data by encrypting data; and a reconfigurable logic chip configured to receive the encrypted input data from the storage device, generate processed data by processing the encrypted input data according to a configuration, and generate encrypted output data by encrypting the processed data.
What exactly they claim (claim 1)
1. A method of operating a storage configured to communicate with a host via a first port and communicate with a reconfigurable logic chip via a second port such that the reconfigurable logic chip is only indirectly connected to the host via the storage, the method comprising: receiving, via the first port of the storage, a host command from the host, the host command including a data processing request; storing, in a non-volatile memory included in the storage, non-encrypted data received from the host via the first port of the storage; reading the non-encrypted data stored in the non-volatile memory included in the storage; encrypting the read non-encrypted data to generate encrypted input data; transmitting, via the second port of the storage, the encrypted input data and a first command to the reconfigurable logic chip, the first command commanding data processing with respect to the encrypted input data; and receiving, via the second port of the storage, encrypted processed data from the reconfigurable logic chip.
