A system to pair devices, comprising: an input output, 10, device configured to be coupled to a computing system ; a secure element to, receive , during a boot process of the system , a first pairing authentication value, receive a message that includes a pairing key, a second pairing authentication value, and a device address of the IO device , and in response to determining that the second pairing authentication value matches the first pairing authentication value, use the pairing key and the device address to establish a trusted channel between the secure element and the IO device ; and a pairing agent to, generate a random pairing authentication value, send , during the boot process, the random pairing authentication value to the secure element , receive, from an operating system module running on the host processor of the computing system , a pairing request that includes the device address of the IO device , generate a random pairing key in response to the pairing request associated with the IO device , send a message to the secure element that includes the pairing key, the previously generated pairing authentication value and the device address of the IO device , send the pairing key to the IO device without making the host operating system software aware of the pairing key, and send a pairing notification to the operating system module . an input output, 10, device configured to be coupled to a computing system ; a secure element to, receive , during a boot process of the system , a first pairing authentication value, receive a message that includes a pairing key, a second pairing authentication value, and a device address of the IO device , and in response to determining that the second pairing authentication value matches the first pairing authentication value, use the pairing key and the device address to establish a trusted channel between the secure element and the IO device ; and receive , during a boot process of the system , a first pairing authentication value, receive a message that includes a pairing key, a second pairing authentication value, and a device address of the IO device , and in response to determining that the second pairing authentication value matches the first pairing authentication value, use the pairing key and the device address to establish a trusted channel between the secure element and the IO device ; and a pairing agent to, generate a random pairing authentication value, send , during the boot process, the random pairing authentication value to the secure element , receive, from an operating system module running on the host processor of the computing system , a pairing request that includes the device address of the IO device , generate a random pairing key in response to the pairing request associated with the IO device , send a message to the secure element that includes the pairing key, the previously generated pairing authentication value and the device address of the IO device , send the pairing key to the IO device without making the host operating system software aware of the pairing key, and send a pairing notification to the operating system module . generate a random pairing authentication value, send , during the boot process, the random pairing authentication value to the secure element , receive, from an operating system module running on the host processor of the computing system , a pairing request that includes the device address of the IO device , generate a random pairing key in response to the pairing request associated with the IO device , send a message to the secure element that includes the pairing key, the previously generated pairing authentication value and the device address of the IO device , send the pairing key to the IO device without making the host operating system software aware of the pairing key, and send a pairing notification to the operating system module . <EOS>
