Abstract

In some embodiments, a technique for authorizing a subsequent message comprises receiving a request to authorize a subsequent message, determining whether the request is valid, and authorizing the subsequent message, if it is determined that the request is valid.

Claims

1. A method for revoking an authorization to authorize another party to send a subsequent message, comprising:

receiving an electronic message via an electronic network;

executing program instructions to determine whether the message is unwanted; and

if it is determined that the message is unwanted;

determining that a certificate is associated with the message, wherein the certificate is associated with a delegated authorization to send the message;

determining a certifying party associated with the certificate; and

revoking an authority of the certifying party.

2. The method of claim 1, wherein the message is an email message.

3. The method of claim 1, wherein revoking an authority associated with the certifying party includes revoking the certificate.

4. The method of claim 3, wherein revoking the certificate includes adding the certificate to a list of revoked certificates.

5. The method of claim 1, wherein revoking an authority associated with the certifying party includes altering a power associated with the certifying party.

6. The method of claim 1, wherein revoking an authority associated with the certifying party includes revoking a trusted certification authority status.

7. A system for revoking an authorization to authorize another party to send a subsequent message, comprising:

a processor that is a component of a computing device, configured to;

receive an electronic message via an electronic network;

determine whether the message is unwanted; and

if it is determined that the message is unwanted;

determine that a certificate is associated with the message, wherein the certificate is associated with a delegated authorization to send the message;

determine a certifying party associated with the certificate; and

revoke an authority of the certifying party; and

a memory coupled with the processor, wherein the memory provides instructions to the processor.

8. The system of claim 7, wherein the message is an email message.

9. The system of claim 7, wherein revoking an authority associated with the certifying party includes revoking the certificate.

10. The system of claim 9, wherein revoking the certificate includes adding the certificate to a list of revoked certificates.

11. The system of claim 7, wherein revoking an authority associated with the certifying party includes altering a power associated with the certifying party.

12. The system of claim 7, wherein revoking an authority associated with the certifying party includes revoking a trusted certification authority status.

13. A computer program product for revoking an authorization to authorize another party to send a subsequent message, the computer program product being embodied in a non-transitory computer readable medium and comprising computer instructions for:

receiving an electronic message via an electronic network;

executing program instructions to determine whether the message is unwanted; and

if it is determined that the message is unwanted;

determining that a certificate is associated with the message, wherein the certificate is associated with a delegated authorization to send the message;

determining a certifying party associated with the certificate; and

revoking an authority of the certifying party.

14. The computer program product of claim 13, wherein the message is an email message.

15. The computer program product of claim 13, wherein revoking an authority associated with the certifying party includes revoking the certificate.

16. The computer program product of claim 15, wherein revoking the certificate includes adding the certificate to a list of revoked certificates.

17. The computer program product of claim 13, wherein revoking an authority associated with the certifying party includes altering a power associated with the certifying party.

18. The computer program product of claim 13, wherein revoking an authority associated with the certifying party includes revoking a trusted certification authority status.
