Executable applications on a gaming machine are verified before they can be executed, for security purposes and to comply with jurisdictional requirements. Unlike in prior systems for authenticating the executable applications, embodiments allow for new executable applications to be provided and verified over time with different private and public key pairs, even after the operating code of the gaming machine is certified by the jurisdiction and deployed in the field.

Methods and systems for creating and managing certificates for gaming machines in a gaming network using a portable memory device. A gaming machine creates a certificate signing request which is stored on a portable memory device at the machine. Then, the memory device is coupled with an appropriate CA server. A certificate batch utility program on the server downloads and processes the CSRs. A certificate services program on the server issues gaming machine certificates according to the CSRs. In one embodiment, the certificates are uploaded onto the memory device, along with copies of certificate authority server certificates, including a root CA certificate. Then, the memory device is coupled with the gaming machine and software on the machine identifies and downloads its certificate based on the certificate file name.

Gaming machine certificate creation and management

Methods and systems for creating and managing certificates for gaming machines in a gaming network using a portable memory device are described. A gaming machine creates a certificate signing request which is stored on a portable memory device at the machine by an operator. The memory device is handed over to a certificate authority (CA) security officer at the casino and is coupled with an appropriate CA server. A certificate batch utility program on the server downloads and processes the CSRs. A certificate services program on the server issues gaming machine certificates according to the CSRs. In one embodiment, the certificates are uploaded onto the memory device, along with copies of certificate authority server certificates, including a root CA certificate. The CA security officer hands the memory device to the casino floor operator. At the machine, the operator inserts or couples the device and software on the machine identifies and downloads its certificate based on the certificate file name. The machine also downloads copies of the CA server certificates which it may use in a certificate chain validation procedure. In another embodiment, the certificates are placed in a shared file on the CA server and retrieved by the gaming machines over a gaming network.

A defogger for the objective lens of a laparoscope provides a channel in a longitudinal direction of the laparoscope. Gas from an insufflator is supplied to the channel exteriorly of a body being operated upon. A deflector is provided at or adjacent the opposite end of the gas flow channel to deflect insufflating gas across the objective lens for maintaining said objective lens clean within said body.
