A method, system, and computer program product for selectively encrypting one or more elements of a document using style sheet processing. Disclosed is a policy-driven augmented style sheet processor (e.g. an Extensible Stylesheet Language, or “XSL”, processor) that creates a selectively-encrypted document (e.g. an Extensible Markup Language, or “XML”, document) carrying key-distribution material, such that by using an augmented document processor (e.g. an augmented XML processing engine), an agent can recover only the information elements for which it is authorized. The Document Type Definition (DTD) or schema associated with a document is modified, such that the DTD or schema specifies a reference to stored security policy to be applied to document elements. Each document element may specify a different security policy, such that the different elements of a single document can be encrypted differently (and, some elements may remain unencrypted). The key distribution material enables a document to be encrypted for decryption by an audience that is unknown at the time of document creation, and enables access to the distinct elements of a single encrypted document to be controlled for multiple users and/or groups of users. In this manner, group collaboration is improved by giving more people easier access to information for which they are authorized, while protecting sensitive data from unauthorized agents. A key recovery technique is also defined, whereby the entire document can be decrypted by an authorized agent regardless of how the different elements were originally encrypted and the access protections which were applied to those elements.

A system and method of handling historical activities for membership changes in group collaboration is presented. A membership manager uses a register service to log group actions that components send to user groups. As such, when the register service receives a member change notification corresponding to a user group, the register service sends action redistribution requests to the components that instruct each of the components to resend the group actions to a new user group member. In one embodiment, the membership manager allows a user to select particular group actions to redistribute to a new member. In this embodiment, the user may also select whether to instruct a component to send event information corresponding to events that have passed, such as a prior month's team meeting notifications, or to only send upcoming event information.

A wireless sensor network virtual MIMO communication strategy based on cooperative groups is called as group collaboration MIMO (GCMIMO). A method similar to the CMIMO is adopted to carrying out clustering on a network for the GCMIMO, and each cluster is managed by two cluster heads, namely a main cluster head and a secondary cluster head. The main cluster heads are used for dividing information source nodes in the corresponding clusters into a plurality of cooperative groups, each cooperative group is composed of two adjacent information nodes, is equivalent to a virtual double-antenna sending end and is used for sending information source data of the cooperative groups, the secondary cluster heads and the main cluster heads are considered as one cooperation group which is called as a main cooperative group and used for receiving and forwarding the data of other cooperative groups, and therefore multi-hop virtual MIMO transmission is achieved. Different from an existing virtual MIMO communication strategy, the GCMIMO does not need to collect information source data through the cluster heads and directly sends the information source data through the cooperative groups, so that the forwarding frequency of the information source data is reduced and the energy efficiency of intra-cluster communication stages is improved. In a simulation experiment, energy consumption analysis of each communication stage of the GCMIMO proves that the GCMIMO effectively lowers the energy consumption of intra-cluster communication and network maintenance frequency, and improves energy efficiency.
