Abstract:

The work addresses the problem of cheating prevention in secret sharing. For any integer , strictly - cheating immune secret sharing scheme under the unconditionally secure is given. It is concluded that the defining function of strictly secret sharing scheme is -resilient and also is -strengthened propagation criterion. Furthermore, its degree is high. So it has better cryptographic properties than that of the known results.

Key words: secret sharing, (strengthened) propagation criterion, correlation immune functions, resilient functions
