A , (m  ) n threshold secret sharing scheme is a method for distributing a secret amongst a group of participants. In a , (m  ) n threshold secret sharing scheme any m participants recover the secret, but no ) 1 (  m participants can [6]. Each of participants is allocated a share of the secret. The secret can only be reconstructed when the shares are combined together [2]. In this paper, we ...

We first explain the notion of secret sharing and also threshold schemes, which can be implemented with the Shamir’s secret sharing. Subsequently, we review social secret sharing [6,10] and its trust function. In a secret sharing scheme, a secret is shared among a group of players who can later recover the secret. We review the construction of a social secret sharing scheme and its application ...

The ancient mutualism between fungus-growing ants and the fungi they cultivate for food is a textbook example of symbiosis. Fungus-growing ants' ability to cultivate fungi depends on protection of the garden from the aggressive microbes associated with the substrate added to the garden as well as from the specialized virulent garden parasite Escovopsis. We examined ants' ability to remove alien...

A (t, n)-threshold secret sharing scheme is a method to distribute a secret among n participants in such a way that any t participants can recover the secret, but no t − 1 participants can. In this paper, we propose two secret sharing schemes using non-abelian groups. One scheme is the special case where all the participants must get together to recover the secret. The other one is a (t, n)-thr...
