Abstract: According to an exemplary embodiment a method for securely storing a message comprises dividing a first message into a first plurality of shares, and storing the first plurality of shares on a storing host together with a second plurality of shares of at least a second message, wherein the storing is performed in a mixed manner.

Abstract: Method of and device for querying of protected data structured in the form of a tree. A corresponding tree of node polynomials is constructed such that each node polynomial evaluates to zero for an input equal to an identifier assigned to a node name occurring in a branch of the data tree starting with the node in question. A tree of blinding polynomials and a tree of difference polynomials are constructed such that each polynomial in the tree of node polynomials equals the sum of the corresponding polynomial in the tree of blinding polynomials and the corresponding polynomial in the tree of difference polynomials. The blinding tree is given to a client, the difference tree to a server. By combining the outcomes of the evaluations of the client and the server, it is possible to identify nodes that match a given query.

Abstract: A height-adjustable workstation main frame includes a pair of telescoping, adjustable legs and a rigid yet efficient fixing frame carried by the upper portions of the legs to provide lateral stability, increased weight bearing capacity and functional flexibility. The same telescoping leg structure is adaptable to receive a motor drive, a manual crank lift or a manually adjusted mechanism for establishing the desired height of the table top. Fore and aft stability is increased by the shape and interengagement of the telescoping inner and outer leg weldments and the use of duplicate, laterally aligned bearing slide assemblies interconnecting the inner and outer leg weldments of each telescoping leg.

Abstract: A combination hammer and casement window opening and closing mechanism operator for use by a framing carpenter includes a head unit having two impact surfaces and a socket in the handle. The socket is used to operate the crank of a casement window opening and closing mechanism, and one of the two impact surfaces is used when the hammer must be used in small, confined areas.
