| 20090313136 | Stateless Methods for Resource Hiding and Access Control Support Based on URI Encryption - An apparatus and method are disclosed for enabling controlled access to resources at a resource provider server. The invention may encrypt or decrypt a portion of a uniform resource identifier (URI), according to a stateless method for hiding resources and/or providing access control support. Upon receipt of a URI having an encrypted portion, the invention decrypts the encrypted portion using a predetermined key to obtain a decrypted segment, extracts additional information from the decrypted segment and forms a decrypted URI, before the decrypted URI is forwarded to a resource producer server. The invention may also encrypt a URI from a resource provider server before it is sent to a client in response to a client request. | 12-17-2009 |
