Abstract: A plurality of computer messages are classified into clusters according to the behavior of the computer messages in the context of a computer resource. For a new message of the plurality of computer messages, it is determined whether the cluster to which the new computer message is classified has been seen previously. A measure is then obtained of the probability that the cluster to which the next new message will be classified has been seen previously.

Abstract: A method of establishing secure groups of trusted contacts with access rights in a secure communication system. The method includes establishing secure groups of trusted contacts in the secure communication system; storing information corresponding to the trusted contacts of a secure group as a secure group in a database; and determining access rights of the secure group and storing the access rights in the database with the stored information corresponding to the secure group.

Abstract: A method of establishing a multiplicity of shared secrets at two mutually authenticated end points in a network. The method includes authenticating a first end point in the network based on an asymmetric key pair and authenticating a second end point based on an asymmetric key pair. Upon successful authentication of the first and second end points, the end points negotiate a shared secret. Multiple shared secret keys are generated from the negotiated shared secret and session keys are computed from the multiple shared secret keys.

Abstract: A communication system including one or more end points, each end point interconnected to a wireless network. The communication system also includes a media network system, the network system contains a registration server for registering device IDs of the end points in the communication system, a database for storing device IDs, one or more media servers for routing calls between end points and a signaling server for selecting one or more media servers to route a call between end points in the communication system based on an algorithm that evaluates one or more predetermined conditions.

Abstract: A plurality of computer messages are classified into clusters according to the behavior of the computer messages in the context of a computer resource. For a new message of the plurality of computer messages, it is determined whether the cluster to which the new computer message is classified has been seen previously. A measure is then obtained of the probability that the cluster to which the next new message will be classified has been seen previously.

Abstract: A communication system providing point to point data encryption including one or more mobile end points, each mobile end point includes mobile equipment and an encryption module. The communication system also includes a network, a first gateway coupled to a Private Branch Exchange (PBX) telephone system, and a second gateway coupled to a Public Switch Networking System (PSTN). The PBX telephone system is connected to a telephone, a conference service and a voicemail service, and the PSTN is connected to a telephone. The network interconnects the one or more mobile end points, first gateway and the second gateway. The first gateway and second gateway each include an encryption module to provide seamless data encryption.

Abstract: A method of establishing trusted contacts with access rights in a secure communication system. The method includes establishing the trustworthiness of an untrusted call received from another end point in a secure communication system and storing information corresponding to the end point as a trusted contact entry in a database if the trustworthiness of the end point is established. Access rights of the trusted contact are determined and stored in the database and any time restrictions are determined and stored in the database.

Abstract: A computer message that is being sent from a consumer to a computer resource is checked to determine whether the computer message meets all of a set of one or more specified conditions. If so, the computer message is compared with a baseline, the baseline containing a set of computer messages which have been classified according to whether or not each of the computer messages of the set represents acceptable behaviour in the context of the computer resource. If the comparison with the baseline determines that the computer message represents acceptable behaviour in the context of the computer resource, the computer message is permitted to be passed to the computer resource.
