| 20210036869 | ESTABLISHING TRUST ON A DATA STORAGE NETWORK - A trust relationship may be established between a host system and a storage system. An asymmetric key pair including a private key unique to a host system and a public key may be generated. During provisioning of the host system to the storage system, the host system may send the public key to the storage system. The storage system may be configured to record the public key for the host system, for example, in a masking table that defines I/O connectivity for logical storage units between a host system and the storage system. The public key may be used later to validate the host system to the storage system. The private key may be stored on the host system and be unreadable, or may be encrypted with an unreadable encryption key stored on the host system. | 2021-02-04 |

After verification, the host device compares the subset of the master revocation list with the revocation list of the host device to determine if the subset of the master revocation list includes a new entry. The new entry is included with the revocation list of the host device. | 2021-02-04 |
| 20210036871 | PROPRIETOR'S IDENTITY CONFIRMATION SYSTEM, TERMINAL MANAGEMENT SERVER, AND PROPRIETOR'S IDENTITY CONFIRMATION METHOD - A terminal A transmits an owner identity confirmation start request to a terminal B, including owner server association information capable of identifying an owner of the terminal and a terminal management server A of the terminal. The terminal B transmits an owner identity confirmation request to the terminal management server B of the terminal, the owner identity confirmation request including the owner server association information received and the owner server association information including information of the terminal B. The terminal management server B transmits, to the terminal management server A, an inter-server owner identity confirmation request including the identity confirmation information of the owner of the terminal B and the owner server association information of the terminal A. The terminal management server A compares the identity confirmation information of the owner of the terminal A with the identity confirmation information received, and confirms the owner identity of the two terminals. | 2021-02-04 |
