Interactive surgical systems with condition handling of devices and data capabilities

A surgical hub configured to authenticate data communications with surgical devices, the surgical hub comprising a control circuit configured to:

• detect that a surgical device is communicatively coupled to the surgical hub;
• transmit a public key associated with the surgical hub to the surgical device;
• receive a message from the surgical device, wherein the message is encrypted using the public key associated with the surgical hub, wherein the encrypted message comprises a shared secret associated with the surgical device and a checksum function associated with the shared secret, and wherein the shared secret comprises an identifier assigned to the surgical device;
• decrypt the encrypted message, using a private key associated with the transmitted public key, to reveal the shared secret and the checksum function;
• receive data communications from the surgical device, wherein each data communication is encrypted using the shared secret received from the surgical device, and wherein each data communication comprises a checksum value, derived via the checksum function, based on the data of each received data communication;
• decrypt each data communication using the shared secret until the surgical device is decoupled from the surgical hub, wherein an integrity of each data communication is verifiable based on its associated checksum value;
• and
• transmit each data communication received from the surgical device to the cloud-based system, wherein each data communication is encrypted using the shared secret received from the surgical device to allow the cloud-based system to decrypt each data communication using the shared secret until the surgical device is decoupled from the surgical hub.

A surgical hub configured to authenticate surgical devices coupled to the surgical hub, the surgical hub comprising:

• a processor;
• and
• a memory coupled to the processor, the memory storing instructions executable by the processor to:
• detect that a surgical device is communicatively coupled to the surgical hub;
• receive an encrypted identifier and a source ID from the surgical device;
• transmit a first message from the surgical hub to a server of a surgical device manufacturer associated with the source ID, wherein the first message comprises the encrypted identifier, and wherein the first message is encrypted using a public key associated with the surgical device manufacturer;
• receive a second message from the server of the surgical device manufacturer, wherein the second message is encrypted using a second public key associated with the surgical hub, and wherein the encrypted second message comprises a shared secret associated with the encrypted identifier of the surgical device;
• decrypt the encrypted second message using a private key associated with the second public key used to encrypt the second message to reveal the shared secret associated with the encrypted identifier of the surgical device;
• decrypt the encrypted identifier of the surgical device using the shared secret to reveal a unique identifier to authenticate the surgical device and its manufacturer;
• and
• transmit a record of the coupling of the surgical device and the surgical hub to at least one of a cloud-based system or a plurality of other surgical hubs communicatively coupled to the cloud-based system in a surgical system, wherein the record links the unique identifier assigned to the surgical device to a unique identifier assigned to the surgical hub.
