In this paper, we propose practical solutions for constructing a family of strong one way permutations such that when a member is chosen uniformly at random, with a high probability we get a one way permutation ., with .(log .), the maximum number of simultaneous hard bits

The various concepts behind SIFF are presented together with a construction of SIFF from any one-way function. Applications of SIFF to many practical problems are also discussed. These include

In this paper, we propose solutions to handle the generalized secret sharing policy. In addition, we investigate two different models for the group: one with a mutually trusted party in the group

Finally, the main result of the work is presented which proves that the concatenation of two layers of modified L-R randomizers is a perfect randomizer.
