发明名称 CREATING AND VALIDATING CRYPTOGRAPHICALLY SECURED DOCUMENTS
摘要 Aspects of the subject matter described herein relate to creating and validating cryptographically secured documents. In aspects, documents are encrypted to protect them from unauthorized access. An entity having namespace ownership rights may create a document in an authorized namespace and sign the document with a private key. Other entities may validate that the document was created by an authorized namespace owner by using a public key available in security data associated with a parent document of the document. For a root document, the public key may be available from a directory service. A namespace owner may change the namespace owner(s) that are allowed to create children of a document.
