A method of digital rights management (DRM), comprising the steps of:
- receiving content at a client computer, wherein the content is encrypted with an encryption key;
- the client computer requesting the encryption key from a server using a digital certificate, wherein the server is remote from the client computer;
- the server receiving the request;
- and
- determining if the digital certificate is valid.
A system for digital rights management comprising:
- a client computer, wherein the client computer includes software comprising instructions for:
- receiving content, wherein the content is encrypted with an encryption key;
- and
- requesting the encryption key from a digital rights management (DRM) server using a digital certificate, wherein the server is remote from the client computer;
- and
- the server, wherein the server includes software comprising instructions for:
- receiving the request;
- and
- determining if the digital certificate is valid.
A computer-readable medium comprising instructions for digital rights management, by:
- receiving content at a client computer, wherein the content is encrypted with an encryption key;
- and
- requesting the encryption key from a digital rights management (DRM) server using a digital certificate, wherein:
- the server is remote from the client computer;
- the server receives the request;
- and
- the server determines if the digital certificate is valid.
A computer-readable medium comprising instructions for digital rights management, by:
- receiving a client computer request, at a digital rights management (DRM) server, for an encryption key using a digital certificate, wherein the client computer receives content that is encrypted with the encryption key;
