    Abstract: Method and apparatus for controlling the routing of data packets in an IP network (200). A DNS system (202) stores a packet admission policy configured for a first end-host (B) that dictates conditions for allowing other end-hosts to get across data packets to the first end-host or not. A routing voucher is defined which is required for routing data packets to the first end-host. The routing voucher is distributed to routers (R) in the IP network. When an address query is received at the DNS system (202) from a second end-host, the voucher is supplied to the second end-host if the configured policy allows the second end-host to convey data packets. Otherwise, the voucher is not supplied. If allowed, the second end-host will add the routing voucher to any data packets directed to the first end-host. When a valid routing voucher is present in a packet at a router (204) in the network, the packet will be forwarded to the next router in the IP network. The router will otherwise discard the packet.

    Abstract: A method and arrangement is disclosed for managing session keys for secure communication between a first and at least a second user device in a communications network. The method is independent of what type of credential each user device implements for security operations. A first user receives from a first key management server keying information and a voucher and generates a first session key. The voucher is forwarded to at least a responding user device that, with support from a second key management server communicating with the first key management server, resolves the voucher and determines a second session key. First and second session keys are, thereafter, used for secure communication. In one embodiment the communication traverses an intermediary whereby first and second session keys protect communication in their respective leg to said intermediary.

    Abstract: A communications apparatus includes a mobile device. The apparatus includes a receiver for receiving at the mobile device a plurality of signals carrying information including received signals which provides randomly varying data related to location of the mobile device. The apparatus includes a random number generator which generates a random number as a function of the data. The apparatus includes a cryptographic key generator which generates a cryptographic key using the random number. A method to establish at a mobile device a random number for cryptographic operations includes the steps of receiving at the mobile device a plurality of signals carrying information including received signals which provides randomly varying data related to location of the mobile device. There is the step of estimating signal entropy for at least one of the received signals in dependence of location where the signals are received by the mobile device. There is the step of selecting the at least one entropy estimated signal having estimated entropy satisfying a predetermined property. There is the step of generating from the at least one entropy estimated signal the random number.

    Abstract: A method of processing binary data representing field elements of an odd-characteristic finite field GF(pk) is described. The method comprises storing binary data representing at least a portion of a field element of an odd-characteristic finite field GF(pk) in a register, p being an odd prime number, the field element comprising k coefficients in accordance with a polynomial-basis representation, the binary data comprising plural groups of data bits, wherein each group of data bits represents an associated one of the k coefficients. The method also comprises executing at least one operation on contents of the register such that the plural groups of data bits are processed in parallel. An apparatus comprising a memory and a processing unit coupled to the memory to carry out the method is also described.
