Assignee:

CoActive Technologies, Inc. - Newton MA

International Classification:

H01H 9/00

US Classification:

200314, 200516

Abstract:

In an embodiment, a membrane switch may include a flexible light guide having a first refractive index. The flexible light guide may include a first wall, an opposing second wall, and one or more additional walls. One or more of the first wall, the second wall and the additional walls may be disposed adjacent to a substance including a second refractive index that is lower than the first refractive index.

International Classification:

H04L 9/08

US Classification:

380278

Abstract:

In one embodiment, a storage device stores a content encryption key, content encrypted with the content encryption key, and a super-distribution key. To re-distribute the content, the storage device creates a super-distribution token by encrypting the content encryption key with the super-distribution key and provides the encrypted content and the super-distribution token to a host device for storage in a target storage device. To access the encrypted content on the target storage device, the target storage device provides the super-distribution token to a server via the host device. The server generates an activation token from the super-distribution token, wherein the activation token contains the content encryption key. The target storage device receives the activation token from the server via the host device, retrieves the content encryption key from the activation token, and decrypts the encrypted content using the retrieved content encryption key.

Abstract:

In one embodiment, a host device creates a super-distribution token by encrypting a content encryption key with a super-distribution key and stores the super-distribution token and encrypted content retrieved from a source storage device in a target storage device. In another embodiment, a host device provides a super-distribution token to a server, wherein the server is configured to generate an activation token from the super-distribution token, receive the activation token from the server, retrieve a content encryption key from the activation token, and decrypt encrypted content received from a storage device using the content encryption key retrieved from the activation token.
