Abstract:

The cryptographic model of cheating immune secret sharing Function is introduced. By using injective functions, it proposes anew method for the construction of cheating-immune secret sharing which has the form (x,y)=x•π(y). It gives a sufficient and necessary condition for a quadratic Boolean function to be cheating-immune. It improves the conclusions given by Josef Pieprzyk

Key words: cryptography, Boolean function, secret sharing, resilient function
