Self-healing supramolecular block copolymers.
Polymer, heal thyself! Supramolecular ABA triblock copolymers formed by dimerization of 2-ureido-4-pyrimidinone (UPy) end-functionalized polystyrene-b-poly(n-butyl acrylate) (PS-b-PBA) AB diblock copolymers have been synthesized, resulting in a self-healing material that combines the advantageous mechanical properties of thermoplastic elastomers and the dynamic self-healing features of supramol...
متن کاملSelf-healing Group Key Distribution
In this paper we propose the self-healing feature for group key distribution through Subset Difference (SD) method proposed by D. Naor et al. The subset difference method is one of the efficient proposals for group key distribution, however, recently a polynomial based solution for key distribution was proposed by D. Liu et al., which has the similar message size but also provides self-healing ...
متن کاملSelf-healing Key Distribution Schemes with Sponsorization
In a self-healing key distribution scheme a group manager enables a large and dynamic group of users to establish a group key over an unreliable network. The group manager broadcasts in every session some packet of information in order to provide a common key to members of the session group. The goal of self-healing key distribution schemes is that, even if the broadcast is lost in a certain se...
متن کاملA New Self-Healing Key Distribution Scheme
A self-healing key distribution scheme enables a group of users to establish a group key over an unreliable channel. In such a protocol, a group manager, to distribute a session key to each member of the group, broadcasts packets along the channel. If some packet gets lost, then users are still capable of recovering the group key using the received packets, without requesting additional transmi...
متن کاملSelf-Healing Key Distribution with Revocation
We address the problem of establishing a group key amongst a dynamic group of users over an unreliable, or lossy, network. We term our key distribution mechanisms self-healing because users are capable of recovering lost group keys on their own, without requesting additional transmissions from the group manager, thus cutting back on network traffic, decreasing the load on the group manager, and...
