A method for hydrophilifying the surface of a substrate by taking advantage of photocatalytic action. The substrate has a photocatalytic titania coating (10). The surface of the photocatalytic coating (10) bears the solid acid that increases a hydrogen bond component ( gamma Sh) in the surface energy in the solid / gas interface of the coating. Photoexcitation of the photocatalyst enhances the hydrogen bond component ( gamma Sh) in the surface energy of the photocatalytic coating (10), accelerating the physical adsorption of molecules of water in the atmosphere through a hydrogen bond (16) onto hydrogen atoms in a terminal OH group (12), bonded to a titanium atom, and a bridge OH group (14) on the surface of the coating. This results in the formation of a high density, physically adsorbed water layer (18) on the surface of the photocatalytic coating (10), thus permitting the surface of the substrate to be easily hydrophilified. The method is applicable to antifogging, antifouling, selfcleaning and cleaning of articles.

In yet another embodiment a pad is placed either periodically or continuously in the windings of the buffer tube to provide an absorbing layer for the residual stresses existing in the buffer tube as it is reeled and after the reeling is complete, combined with re-reeling the buffer tube onto a second reel after the buffer tube has cooled (after manufacture), where the pad is removed during the re-reeling process. Additionally, the present invention can have the layers of buffer tube separated with rigid, cylindrical panels separating the layers. The present inventive method also combines any, or all, of the above steps to aid in achieving a substantially uniform excess fiber length along the length of the reeled buffer tube.

A shared-key encryption scheme that uses identically keyed block-cipher calls, low additional overhead, supports the encryption of arbitrary-length strings, produces a minimal-length-ciphertext, and is fully parallelizable. In one embodiment, “OCB”, a key shared between communicating parties is mapped to a key variant using the block cipher. The key variant is mapped into a sequence of basis offsets using shifts and conditional xors. To encrypt a message using a nonce, a nonce-dependent base offset is formed, and then a sequence of offsets is constructed by starting with the base offset and then xoring, for each offset, an appropriate basis offset. The message is partitioned into message blocks of the same length as the block length of the block cipher, along with a message fragment that may be shorter. Each message block is combined with a corresponding offset, enciphered, and then combined again with the offset, yielding a ciphertext block. The message fragment is xored with an appropriately computed pad to give a ciphertext fragment. A checksum is formed using the message blocks, the message fragment, and the pad. The checksum is combined with an offset and enciphered to yield a tag. The encrypted message includes the ciphertext blocks, the ciphertext fragment, and the tag.

A method of securely accessing at a client device content from a server without using the non-volatile memory of the client device is disclosed. The bypassing of non-volatile memory lessens the security risk of unauthorized viewing of the server originated content. An transport mechanism is initiated on a client device and creates a document container. Downloaded documents from a server are mapped into the document container and saved within the document container in volatile memory. Substitute menus are generated within the container to replace application menus. User documents are saved directly to the originating server via the substitute menus. The downloaded copies in volatile memory automatically delete when the document container is destroyed thereby reducing security concerns of unauthorized viewing of the content at the client device.
