Access control in a hierarchy plays an important role in today's communication networks.To guarantee the quality of communication services it is necessary to construct a low-computation dynamic access control scheme for the use to obtain the secure information.Therefore, we propose an efficient identity-based cryptographic key assignment scheme in which the cryptographic key of each user is calculated through a one-way hash function.The key generation and key derivation are quite simple and the number of the public/secret parameters for each authenticated user is small; which will make our scheme very suitable for the hardware-limited users such as mobile units .
