A Private Scheme for distributed ,Shared Secret Generation
Date: June 20 - June 25, 1999
We present a scheme for shared secret generations by n members that combines the contributions the members in a fashion such that the individual contribution of each member is not exposed to anyone- including other members. We note that for an external attacker trying to break the n L-bit secrets of the members, the effective search space dimension is nL, meaning that all n keys must be broken simultaneously in order to crack system integrity. We also note that the scheme provides “Unconditional Secrecy”.
