Abstract
Threshold schemes are adaptable cryptographic primitives that distribute tr ust in secret data by requiring k out of n entities to co-operate before th e data can be recovered. An important security management issue relating to threshold schemes is the problem of updating the parameters of a threshold scheme. The paper discusses serious shortcomings in two proposed protocols for threshold parameter update.
