Techniques are provided for dynamically establishing and managing trust relationships. A first principal initially requests a community list. The community list includes identities of one or more second principals with which the first principal can establish trusted relationships with. The community list is associated with a trust specification. The trust specification defines the policies and access rights associated with interactions between the first principal and the second principals during any active trusted relationships. The first principal can dynamically subdivide, manage, and modify entries of the community list and the trust specification, assuming any such modifications are permissible according to global contracts and policies associated with the first principal.

Techniques are provided for preserving and managing identities within an audit log. Initial entries into a log do not include an explicit and direct reference to an agent that performs a transaction; rather, the agent acquires a temporary transaction identity for the transaction and an indirect reference to the transaction identity is written to the log while the transaction is pending. Once the transaction completes a direct reference to the transaction identity is written to the log, the identity of agent remains transparent until the identity of the agent expires, if at all.

Techniques are provided for allocating resources over a network. A resource consumer requests access to a resource over a network. As part of that request, the resource consumer acquires information that permits it to securely communicate with a resource provider. The resource provider controls the resource and once satisfied with the security of a request from a resource consumer allocates the resource for access by the resource consumer.

Techniques are provided for dynamically establishing and managing authentication and trust relationships. An identity service acquires and evaluates contracts associated with relationships between principals. The contracts permit the identity service to assemble authentication information, aggregated attributes, and aggregated policies which will drive and define the various relationships. That assembled information is consumed by the principals during interactions with one another and constrains those interactions. In some embodiments, the constraints are dynamically modified during on-going interactions between the principals.

Techniques for attesting to content received from an author (sender) are provided. A sender's content is represented by a message digest. The message digest is signed by an identity service. The signed message digest represents an attestation as to the authenticity of the content from the sender. The sender transmits the signed message digest and content in a message to a recipient. The recipient verifies the signature and message digest to authenticate the content from the sender.

Techniques for providing role-based security with instance-level granularity are provided. A security service detects a request made by a principal for access to a resource. Access to the resource is conditioned on a status of a role. The role is associated with the request, the principal, and the resource. The security service evaluates a constraint associated with the role to determine the status. The status is subsequently consumed to determine whether access to the resource for the purposes of satisfying the request is permissible.

Techniques for the remote authorization of secure operations are provided. A secure security system restricts access to a secure operation via an access key. An authorization acquisition service obtains the access key on request from the secure security system when an attempt is made to initiate the secure operation. The authorization acquisition service gains access the access key from a secure store via a secret. That is, the secret store is accessible via the secret. The secret is obtained directly or indirectly from a remote authorization principal over a network.

Techniques for federating and for attesting to online reputations are provided. A variety of reputation sources supply portions of reputation information about a principal. The portions are aggregated and optionally weighted to form a summary of reputation information. The summary is then represented as an attestation and optionally signed by the service providing the attestation.
摘要:
Crafted identities are provided. A statement is provided to the principal for using a crafted identity. The statement includes an identifier that provides access to a resource when presented by the principal to the resource. The statement also includes one or more roles and permissions for the crafted identity when accessing the resource.

Techniques are provided for establishing privileged paths for data packets over a network. A data packet is received with a header; the header includes a route selector. The route selector assists in resolving a privileged path for the data packet. The data packet is injected into the network over the resolved privileged path.
