• A novel cryptographic key assignment scheme for dynamic access control in a user hierarchy is presented. Based on Rabin's public key system and Chinese remainder theorem, each security class SC_i is assigned a secret key K_i and some public parameters. In our scheme, a secret key is generated in a bottom-up manner so as to reduce the computation time for key generation and the storage size for public parameters. We also show that our proposed scheme is not only secure but also efficient.
