    摘要: Information can be added to the headers of email messages to ensure the messages are delivered using encryption, without the user having to manage keys or perform the encryption. A user can select an option in an email program that causes a flag to be added to the message header. Each mail server along the delivery path can provide (or expose) information about the type(s) of encryption supported, and if the encryption is not sufficient then the message will not be delivered to that server. This ensures the transport will remain encrypted before delivering the message to the next hop along the path. If the message cannot be delivered encrypted then the message will not be transmitted past that point. An end user then only needs to click a button or perform another such action to ensure encrypted message delivery.

    摘要: System load, such as load caused by a denial of service attack, is managed by requiring those requesting access to the system to provide proof of work. A system receives, from a requestor, a request for access to the system. Before the request can be processed, the system provides a challenge to the requestor. The requestor obtains a solution to the challenge and provides proof of having obtained the solution. The system verifies the correctness of the solution and, if the correct solution is verified, the system services the request.

    摘要: Systems, methods, and computer readable media are described for validating objects stored in a web cache. In one embodiment, a computing device caches objects received while accessing networked content over a network. The computing device generates a description of conditions associated with the caching of the objects. When the computing device accesses networked content via a second network, the computing device or a remote server connected thereto utilizes the description to determine whether an object in the cache is trusted or untrusted. The server manages a policy that defines rules for making the determination. The policy can be generated based on descriptions received from a plurality of devices.
