The paper describes an implementation of Shamir secret sharing schemes based on exponentiation in Galois fields. It is shown how to generate shares so that the scheme has disenrollment capability. A family of conditionally secure Shamir schemes is defined and its disenrollment capability is described. We also examine the problem of covert channels which are present in any secret sharing scheme.
