    Abstract: A computer-implemented method for obscuring network services may include (1) identifying a local network comprising at least one client and at least one host, where the host provides a service that is not bound to any routable address on the local network and the client is expected to send messages to the service, (2) provisioning the client with a proxy that intercepts the messages directed to the service by the client, identifies the host that provides the service, and adds at least one layer of encryption to the messages, (3) configuring the proxy to route the messages through an onion routing network within the local network that comprises at least one onion routing node, and (4) configuring the onion routing network to remove the at least one layer of encryption from the messages before forwarding the messages. Various other methods, systems, and computer-readable media are also disclosed.

    Abstract: A process for accessing a data storage device of a cloud computer system CCS through a gateway computer system GCS includes setting up a protected connection over the Internet between a first piece of terminal equipment of the user and the GCS by inputting the URL of the CCS into a program of the piece of terminal equipment, and using a modified DNS for name resolution of the URL, so that the protected connection is set up with the GCS instead of with the CCS; transferring a file over the protected connection from the terminal equipment to the GCS; setting up a session over the network between the GCS and the cloud computer system; encrypting the file by the GCS using the cryptographic key; transferring the encrypted file through the session from the GCS to the CCS; and storing the encrypted file in the data storage device of the CCS.

    Abstract: Preventing enterprise or other protected content data from “leaking” from being under secure management on a device, for example by virtue of being viewed using an untrusted app on the device, is disclosed. An indication is received that a content to be provided to a first mobile application on a mobile device is to be protected against unauthorized access at the mobile device using unauthorized applications other than the first mobile application. The content is encrypted while in transit to the mobile device, using a key associated with a second mobile application authorized to be used to access the content at the mobile device.

    Abstract: A server apparatus according to an embodiment generates a random number on receiving from a user apparatus a notification showing that a re-encryption key should be updated, and calculates re-encryption key data on the basis of the re-encryption key stored and the random number generated. The server apparatus transmits the re-encryption key to the user apparatus and receives, from the user apparatus, the user private key not updated yet and re-encryption key updating data calculated from the re-encryption key data on the basis of the user private key updated. The server apparatus calculates the re-encryption key updated, on the basis of the re-encryption key updating data and the random number, and replaces the re-encryption key stored in the storage device with the updated re-encryption key.
