    摘要： A method, apparatus and computer program product are provided to provide cryptographical key separation for handovers. A method is provided which includes calculating a key based at least in part upon a previously stored first intermediary value. The method also includes calculating a second intermediary value based at least in part upon the calculated key. The method additionally includes sending a path switch acknowledgement including the second intermediary value to a target access point. The method may further include receiving a path switch message including an indication of a cell identification and calculating the encryption key based upon the indication of the cell identification. The method may further include storing the second intermediary value. The calculation of the key may further comprise calculating the key following a radio link handover. Corresponding apparatuses and computer program products are also provided.

    摘要： Message authentication in an ad-hoc network. Upon creation of a message, a message authentication code is created using a key shared with members of a group comprising a subset of nodes of the ad-hoc network. The message authentication code may be created using a cryptographic process having the message and a message identifier as inputs. After or in parallel with broadcast of the message, a pointer to the message is broadcast. The message authentication code is publicly broadcast and those members of the group among which the key has been shared are able to authenticate the message as coming from a particular sender.

    摘要： A method for providing efficient management of certificate revocation may comprise storing a list of identifiers of digital certificates including a revocation list defining a list of revoked certificates in an accumulator, storing a witness value in association with at least some entries in the revocation list in which the witness value provides proof of the membership or non-membership of an identifier in the revocation list, enabling generation of a new accumulator and a new witness value responsive to each insertion or deletion of an entry in the revocation list, and enabling batch updates to the revocation list using a reduced bitlength value generated based on to a ratio of a value generated based on elements added to the revocation list to a value generated based on elements deleted from the revocation list. A corresponding apparatus is also provided. A method for certificate authorities (CA) that use Bloom filters for certificate revocation list (CRL) compression that enables the CA to hash only the entry that is to be un-revoked so that a good compression rate may be provided while avoiding computation of the entire CRL for each un-revocation.
