Abstract: An architecture integrates spreadsheet functionality into tables commonly used in word processing programs and HTML documents. The architecture presents a table user interface (UI) that resembles a table when not being edited and adds spreadsheet elements to the table when being edited. Underlying the table UI, the architecture separates data handling functions from presentation functions. The architecture includes a table appearance manager to manage how the table appears in a document including such characteristics as table resizing, selection, cut, copy, paste, split, merge, table formatting and so on. The architecture also has a spreadsheet functionality manager to manage the spreadsheet functions for the table, such as recalculation, formula handling, sorting, referencing, and the like.

Abstract: Systems and methods that allow the formation and distribution of session keys amongst a dynamic group of users communicating over an unreliable, or lossy, network.

Abstract: A method and system for encrypting a first piece of information M to be sent by a sender [100] to a receiver [110] allows both sender and receiver to compute a secret message key using identity-based information and a bilinear map. In a one embodiment, the sender [100] computes an identity-based encryption key from an identifier ID associated with the receiver [110]. The identifier ID may include various types of information such as the receiver's e-mail address, a receiver credential, a message identifier, or a date. The sender uses a bilinear map and the encryption key to compute a secret message key gIDr, which is then used to encrypt a message M, producing ciphertext V to be sent from the sender [100] to the receiver [110] together with an element rP. An identity-based decryption key dID is computed by a private key generator [120] based on the ID associated with the receiver and a secret master key s.

Abstract: A browser remotely retrieves electronic documents from a remote computer network for viewing by a user. For enhancing responsiveness, the browser initially displays an electronic document without a background image so that the electronic document is initially displayed more quickly. The browser also prioritizes downloading of embedded images of the document by their incorporation in the currently visible portion of the electronic document. Further, the browser dynamically creates additional connections for retrieving resources incorporated into the electronic document from the remote computer network.
