Abstract
A transport layer security (TLS) connection is established between a signature device and the host computer via an interface (e.g., a universal serial bus (USB) interface). The signature device acts as a TLS server, and the host computer acts as a TLS client. Data such as pen data, control data, or image data may be received or transmitted via a USB bulk transfer mechanism. In one aspect, the host computer sends a command via the interface to the signature device to generate a new key pair, receives a certificate signing request (CSR) from the signature device via the interface, sends the CSR to a user certificate authority, receives a public key certificate from the user certificate authority, and sends the public key certificate to the signature device via the interface.
