Abstract: Transport Layer Security (TLS) connection establishment between a client and a server for a new session is enabled using an ephemeral (temporary) key pair. In response to a request, the server generates a temporary certificate by signing an ephemeral public key using the server's private key. A certificate chain comprising at least the temporary certificate that includes the ephemeral public key, together with a server certificate, is output to the client by the server, which acts as a subordinate Certificate Authority. The client validates the certificates, generates a session key and outputs the session key wrapped by the ephemeral public key. To complete the connection establishment, the server applies the ephemeral private key to recover the session key derived at the client for the new session. The client and server thereafter use the session key to encrypt and decrypt data over the link. The ephemeral key pair is not reused.

Abstract: Disclosed is an instrument for balancing a knee. The instrument has a first plate (10) coupled to a second plate (50) by a plurality of adjusters (152A, 152B, 152C). The adjusters are actuatable to vary the gap between the first and second plates. Each adjuster is coupled to the second plate by a joint having at least two degrees of freedom. Also disclosed is an outrigger (300). The outrigger includes a body featuring a connection component configured to be received and held by a slot (34) of the instrument. The slot is arranged to align a blade of a surgical saw with a portion of a knee to be cut. Also disclosed is a method of balancing a knee using the instrument and a method of fabricating the instrument.
