摘要:
In a method of provisioning a virtual machine (VM) to a computing network (401), a VM manager or provisioner (403, 408) encrypts a virtual machine using a key bound to at least one security profile indicative of one or more security requirements that a computing resource (402) of the computing network (401) must satisfy in order to be able to decrypt the VM. A key for use in decrypting the VM has previously been sealed into multiple (and preferably into all) computing resources (402) in the network into which the VM is to be provisioned, and has been sealed such that a computing resource can obtain the key only if it is in a state that satisfies the security profile, or at least one security profile, to which the key is bound The VM manager or provisioner (403, 408) creates a VM launch package that includes the encrypted VM and that also includes a key that may be used in decrypting the encrypted VM. When the VM launch package is received at a computing resource (402), the computing resource will not be able to recover the key for use in decrypting the VM—and hence will be unable to decrypt the VM—unless the computing resource satisfies the security requirements indicated by the security profile. The VM manager or provisioner can thus be sure that the VM will not be launched on a computing resource that does not meet the desired security profile. Alternatively the VM manager or provisioner (403, 408) may send a token corresponding to a desired security profile with an encrypted VM. A computing resource uses the token to obtain a key to decrypt the VM but the computing resource will not be able to recover the key unless the computing resource satisfies the security requirements indicated by the token.

The present invention aims at an effective approach to radio access system attachment in a heterogeneous communication network environment. According to the present invention, cooperation between different radio access systems is executed to advertise one radio access system in another. After receipt of a secure advertisement from a control unit of the advertising radio access system, a broadcasting unit of the receiving radio access system broadcasts advertisement information in relation to the secure advertisement in the communication network. Therefore, according to the present invention, a user terminal may at any time receive broadcasted advertisement information while establishing a trusted relationship with advertiser.

A method is presented of establishing communications with a Virtual Machine, VM, in a virtualised computing environment using a 3GPPcommunications network. The method includes establishing a Machine-to-Machine Equipment Platform, M2MEP, which comprises a Communications Module, CM, providing an end-point of a communication channel between the 3GPP network and the VM. A virtual Machine-to-Machine Equipment is established that comprises a VM running on the M2MEP and a downloadable Subscriber Identity Module, associated with the CM. The Subscriber Identity Module includes security data and functions for enabling access via the 3GPP network. The CM utilises data in the Subscriber Identity Module for controlling communication over the communication channel between the VM and the 3GPP network.

The present invention relates to methods and devices for detecting persistency of a first network node (12). In a first aspect of the invention, a method is provided comprising the steps of monitoring (S101), during a specified observation period, whether the first network node has established a connection to a second network node (13), and determining (S102) a total number of sessions of connectivity occurring during said specified observation period in which the first network node connects to the second network node. Further, the method comprises the steps of determining (S103), from the total number of sessions, a number of sessions comprising at least one communication flow between the first network node and the second network node, and determining (S104) inter-session persistence of the first network node on the basis of the total number of sessions and the number of sessions comprising at least one communication flow.

摘要:
A framework for providing cluster-wide cryptographic operations, including: signing, sealing, binding, unsealing, and unbinding. The framework includes an interface module (a.k.a., HAT agent) on each of a plurality of nodes in the cluster. Each HAT agent is configured to respond to an application's request for a cluster crypto operation by communication with other HAT agents in the cluster and utilizing a trusted platform module local to the node where the HAT agent resides.

A system, method, and node for protecting a telecommunication system against a mobile and multi-homed attacker, MMA (10). The telecommunication system includes one or more correspondent nodes, CN, (102, 104) for transferring data packets. A mobile and multi-homed network node, MMN, (108) associated with the MMA communicates and receives data packets with the CN. An access router, AR, (106) transferring data between the MMN and the CN performs a reachability test with the MMN to determine if the MMN is still reachable. The AR sends a message to the CN to flush cached information associated with the MMN if the MMN is not reachable by the AR. The CN, upon receiving the message to flush cached information, flushes binding cache entries associated with the MMN from the CN.
