Abstract

Methods and systems for faster and more efficient smart card logon and for giving a client device full domain access in a remote computing environment are described herein. Components used to implement fast smart card logon may also be used to implement a federated full domain logon. A virtual smart card credential, which may be ephemeral, may be issued based on the acceptance of an external authentication event. Example external authentication events include logon at a Security Assertion Markup Language (SAML) Identity Provider, smart card authentication over TLS or SSL, and alternative authentication credentials such as biometrics or one-time password (OTP) without AD password. Moreover, the certificate operation interception components from fast smart card logon may be used to enable interaction with the virtual smart card without fully emulating a smart card at the PC/SC API level. The virtual smart card may be created locally at the authentication server or on a separate server that may be highly protected.

First claim

What is claimed is:

1. A method comprising:
storing a certificate at a credential mapper of a server device;
corresponding, by the server device, a token to the certificate stored at the credential mapper;
receiving, at the server device and from a client device, the token;
determining, at the server device, whether the client device has authenticated with an identity providing device based on the token received from the client device;
in response to determining that the client device has authenticated with the identity providing device based on the token, generating a temporary certificate based on the certificate stored at the credential mapper;
after generating the temporary certificate based on the certificate stored at the credential mapper, sending, to the client device, the temporary certificate for granting the client device access to a domain;
encrypting, using the temporary certificate, a reference to a credential managed by the credential mapper; and
sending the encrypted reference to a virtualization agent managing one or more virtual resources.

2. The method of claim 1 , wherein determining whether the client device has authenticated with the identity providing device comprises:
sending, by the server device to the identity providing device, information from the token received from the client device; and
receiving, from the identity providing device, confirmation that the client device has authenticated with the identity providing device.

3. The method of claim 1 , wherein determining whether the client device has authenticated with the identity providing device comprises performing one or more of the following:
determining, by the credential mapper of the server device, whether the token received from the client device corresponds to a token issued by the identity providing device;
determining, by a gateway service of the server device, whether the token received from the client device corresponds to the token issued by the identity providing device; or
determining, by an application store of the server device, whether the token received from the client device corresponds to the token issued by the identity providing device.

4. The method of claim 1 , further comprising:
linking the temporary certificate to a proof key at the client device, wherein the sending the temporary certificate comprises sending the temporary certificate in response to a determination that the client device has the proof key.

5. The method of claim 1 , wherein the temporary certificate comprises a time-limited certificate.

6. The method of claim 1 , wherein the credential managed by the credential mapper comprises a virtual smart card managed by the credential mapper, and wherein the temporary certificate comprises a smart card class certificate.

7. An apparatus comprising:
a processor; and
memory storing computer-executable instructions that, when executed by the processor, cause the apparatus to:
store a certificate at a credential mapper of the apparatus;
correspond a token to the certificate stored at the credential mapper;
receive, from a client device, the token;
determine whether the client device has authenticated with an identity providing device based on the token received from the client device;
in response to determining that the client device has authenticated with the identity providing device based on the token, generate a temporary certificate based on the certificate stored at the credential mapper;
after generating the temporary certificate based on the certificate stored at the credential mapper, send, to the client device, the temporary certificate for granting the client device access to a domain;
encrypt, using the temporary certificate, a reference to a credential managed by the credential mapper; and
send the encrypted reference to a virtualization agent managing one or more virtual resources.

8. The apparatus of claim 7 , wherein determining whether the client device has authenticated with the identity providing device comprises:
send, to the identity providing device, information from the token received from the client device; and
receive, from the identity providing device, confirmation that the client device has authenticated with the identity providing device.

9. The apparatus of claim 7 , wherein determining whether the client device has authenticated with the identity providing device comprises performing one or more of the following:
determining, by the credential mapper of the apparatus, whether the token received from the client device corresponds to a token issued by the identity providing device;
determining, by a gateway service of the apparatus, whether the token received from the client device corresponds to the token issued by the identity providing device; or
determining, by an application store of the apparatus, whether the token received from the client device corresponds to the token issued by the identity providing device.

10. The apparatus of claim 7 , wherein the memory stores computer-executable instructions that, when executed by the processor, cause the apparatus to:
link the temporary certificate to a proof key at the client device, wherein the sending the temporary certificate comprises sending the temporary certificate in response to a determination that the client device has the proof key.

11. The apparatus of claim 7 , wherein the temporary certificate comprises a time-limited certificate.

12. The apparatus of claim 7 , wherein the credential managed by the credential mapper comprises a virtual smart card managed by the credential mapper, and wherein the temporary certificate comprises a smart card class certificate.

13. A method comprising:
sending, by a client device and to an identity providing device, credentials for authenticating the client device with the identity providing device;
receiving, at the client device and from the identity providing device, a token indicating that the client device is authenticated with the identity providing device;
sending, by the client device and to a server device, the token;
receiving, by the client device and from the server device, a temporary certificate for accessing a domain, wherein the temporary certificate is generated based on a certificate stored at a credential mapper of the server device; and
in response to the client device receiving the temporary certificate for accessing the domain sending, by the client device and to a virtualization agent managing one or more virtual resources, the temporary certificate for accessing the domain.

14. The method of claim 13 , wherein the server device uses the token to determine whether the client device is authenticated with the identity providing device.

15. The method of claim 13 , wherein the token is linked to the certificate stored at the credential mapper of the server device.

16. The method of claim 13 , wherein the temporary certificate comprises a time-limited certificate.

17. The method of claim 13 , wherein the temporary certificate comprises a smart card class certificate.

18. The method of claim 1 , wherein the token received at the server device and from the client device comprises a token modified by the identity providing device.

19. The apparatus of claim 7 , wherein the token received from the client device comprises a token modified by the identity providing device.

20. The method of claim 13 , wherein the token sent by the client device to the server device comprises a token modified by the identity providing devic
