US 11,907,382 B2 · Secure access to accessory device resources

Abstract

An accessory device receives authentication information from a host computing device connected thereto and determines whether the authentication information is valid. If the authentication information is valid, the accessory device applies a first access policy that specifies whether the accessory device can provide the host computing device with access to none, some, or all of various computing resources of the accessory device. If the authentication information is not valid, the accessory device applies a second access policy that is different than the first access policy. The accessory device can also be provisioned with access policies by a host computing device if the host computing device successfully authenticates with the accessory device. In either case, authenticating the host computing device may include verifying a digital signature of a certificate provided by the host computing device using a public key of a certificate authority that has been provisioned to the accessory device.

Dependent claims

A method performed by an accessory device, comprising:

receiving a host access policy management command and authentication information from a host computing device that is connected to the accessory device, the host access policy management command indicating that a host access policy be set on, modified on, or removed from the accessory device, the host access policy specifying whether a host computing device that is subsequently connected to the accessory device is to be provided access to each of one or more computing resources accessible to the accessory device;
determining whether the authentication information is valid;
in response to at least determining that the authentication information is valid, executing the host access policy management command;
and
in response to at least determining that the authentication information is not valid, denying execution of the host access policy management command.

2 more elements

An accessory device, comprising:

a processor circuit;
and
a memory that stores program code that, when executed by the processor circuit, performs operations, the operations comprising:
receiving a host access policy management command and authentication information from a host computing device that is connected to the accessory device, the host access policy management command indicating that a host access policy be set on, modified on, or removed from the accessory device, the host access policy specifying whether a host computing device that is subsequently connected to the accessory device is to be provided access to each of one or more computing resources accessible to the accessory device;
determining whether the authentication information is valid;
in response to at least determining that the authentication information is valid, executing the host access policy management command;
and
in response to at least determining that the authentication information is not valid, denying execution of the host access policy management command.
