Technologies for authentication and single-sign-on using device security assertions

A method for remote device authentication, the method comprising:

• receiving, by a computing device, an authentication request from a client computing device;
• transmitting, by the computing device, an authentication challenge to the client computing device in response to receiving the authentication request;
• receiving, by the computing device, an authentication challenge response from the client computing device in response to transmitting the authentication challenge, wherein the authentication challenge response includes a resource access token indicative of a security assertion of the client computing device;
• determining, by the computing device, whether the client computing device is trusted based on the resource access token of the authentication challenge response;
• and
• transmitting, by the computing device, a successful authentication response to the client computing device in response to determining that the client computing device is trusted.

One or more computer-readable storage media comprising a plurality of instructions that in response to being executed cause a computing device to:

• receive an authentication request from a client computing device;
• transmit an authentication challenge to the client computing device in response to receiving the authentication request;
• receive an authentication challenge response from the client computing device in response to transmitting the authentication challenge, wherein the authentication challenge response includes a resource access token indicative of a security assertion of the client computing device;
• determine whether the client computing device is trusted based on the resource access token of the authentication challenge response;
• and
• transmit a successful authentication response to the client computing device in response to determining that the client computing device is trusted.
