MOBILE DEVICE USER STRONG AUTHENTICATION FOR ACCESSING PROTECTED NETWORK RESOURCES

Systems and methods for strong user authentication for accessing protected applications by mobile computing devices. An example method may comprise: receiving, by a mobile computing device, a cryptographic nonce via a first communication interface; transmitting, via a second communication interface, an authentication request using the cryptographic nonce, to an authentication server via an HTTP proxy server; receiving a resource access token from the authentication server; and transmitting a computing resource access request using the resource access token.
