摘要: Abstract: Secret sharing schemes are very important techniques for the key management. To
provide more efficient and flexible alternatives for the applications of secret sharing, this
paper presents a dynamic multi-secret sharing scheme. A significant characteristic of the
proposed scheme is that each participant has to keep only one master secret share which
can be used to reconstruct different group secrets according to the number of threshold
values. By applying successive one-way hash functions and the exclusive OR (XOR)
operation, the proposed scheme is secure against the notorious conspiracy attack even
though the pseudo secret shares are compromised. Further, when one of the group secrets
is updated with a new one, each participant’s master secret share is still unchanged, i.e.,
these master secret shares are truly multi-use instead of one-time-use.
