Hierarchical key management scheme using polynomial interpolation
Manik Lal Das, Ashutosh Saxena, Ved Prakash Gulati, Deepak B. Phatak · ACM SIGOPS Operating Systems Review · 2005
We present a hierarchical key management scheme using cryptographic hash function and Newton's polynomial interpolation for users key and system resources management. A similar technique has been proposed in 2002 by Shen and Chen, but their scheme suffers large computational overhead and security weakness. We show that our scheme is secure and efficient in comparisons to the Shen and Chen's scheme.
