    摘要： A system including a pseudo-random number generator having a register to store an extended state having a reduced state and a dynamic constant, an initialization module to initialize a part of the extended state based on a Key and/or an Initial Value, a state update module to update the reduced state, an output word module to generate output words, the state update module and the output word module being adapted to operate through cyclical rounds, each round including updating the reduced state and then generating one of the output words, and an update dynamic constant module to update the dynamic constant, wherein in a majority of the rounds, updating of the reduced state and/or generation of the output word is based on the dynamic constant, and the dynamic constant is only updated in a minority of the rounds. Related apparatus and method are also described.

    摘要： A block cipher system for encrypting a plurality of blocks from plaintext to ciphertext, each of the blocks being associated with a constant root key, the system including an encryption key module to determine an input key for each of blocks based on a function having a plurality of inputs including the root key and an initialization vector, for a first one of the blocks, and the plaintext of at least one of the blocks which was previously encrypted and the root key, for the blocks other than the first block, and an encryption module to encrypt each of the blocks based on the input key determined for each of the blocks, respectively. Related apparatus and methods also included.

    摘要： A method for granting a grace period entitlement, the method comprising receiving a grace period entitlement message, establishing whether a grace period flag indicates that a grace period may be granted, granting a grace period to an expired entitlement based, at least in part, on the grace period entitlement message, only if the grace period flag is “off”, and setting the grace period flag to indicate that the grace period has been granted. Related methods and apparatus are also described.
