摘要： A method for managing data in a preferably non real-time sensor network, wherein the network comprises a multitude of sensor nodes to sense data, wherein the network is divided into clusters with each consisting of several sensor nodes, wherein within each cluster a sensor node acts as aggregator node to aggregate the sensed data of the rest of the sensor nodes of the cluster, and wherein always a pre-configurable number of neighbored clusters are combined to groups and the data aggregated within a cluster are stored by the aggregator node of the cluster itself and in addition by another aggregator node of a cluster of the respective group is characterized in that the data is encrypted with homomorphic methods before being stored persistently.

摘要： This invention provides a user friendly, email encryption system allowing users to send and receive encrypted messages for registered and unregistered users. Encrypted messages can be sent to registered or non-registered users by transmitting the encrypted message to cloud system servers. The cloud system servers acquire certificates from certificate authorities or any end-to-end exchange of keys between the sender and the recipient of the encrypted message. For registered users, messages sent by senders are encrypted by the sender and sent to the cloud system servers which decrypt the message and re-encrypt the message with the recipient's key. For non-registered users, once the encrypted message is decrypted at the cloud system servers, another message is sent to the non-registered informing them that an encrypted message awaits them if they select a link in the message which allows them to log into the cloud system servers and view the original message.
