Molecular self-assembly appears to be a promising route to bottom-up fabrication of complex objects. Two major obstacles are how to create structures with more interesting organization than periodic or finite arrays, and how to reduce the fraction of side products and erroneous assemblies. Algorithmic self-assembly provides a theoretical model for investigating these questions: the growth of ar...

As the computing systems become more and more complex, new technology and approach are desired to construct the system, so as to make them more reliable or self-healable. A modeling framework to generating selfhealing system is proposed in this paper. The model framework consists of function model, fault model, self-healing model, model composition mechanism for integration of the function mode...

In this talk we consider an extended failure model for communication software: Instead of having to handle only external failures like lost or corrupted data packets, invalid routes and crashing nodes, we request the software to also handle internal errors. Internal errors can be the unfaithful execution of some instructions or the partial loss of the code base. We then ask whether software is ...

In the problem of reliable multiparty computation (RC), there are n parties, each with an individual input, and the parties want to jointly compute a function f over n inputs. The problem is complicated by the fact that an omniscient adversary controls a hidden fraction of the parties. We describe a self-healing algorithm for this problem. In particular, for a fixed function f , with n parties ...

Unattended wireless sensor networks (UWSNs) operating in hostile environments face the risk of compromise. Unable to off-load collected data to a sink or some other trusted external entity, sensors must protect themselves by attempting to mitigate potential compromise and safeguarding their data. In this paper, we focus on techniques that allow unattended sensors to recover from intrusions by s...

Synthetic materials that are capable of autonomous healing upon damage are being developed at a rapid pace because of their many potential applications. Despite these advancements, achieving self-healing in permanently cross-linked hydrogels has remained elusive because of the presence of water and irreversible cross-links. Here, we demonstrate that permanently cross-linked hydrogels can be eng...

Self-healing systems tackle the issue of ever increasing complexity of software and its management. Selfhealing systems provide solutions for the software systems to manage themselves and recover from errors. There are multiple approaches to self-healing systems ranging from agent based solutions to frameworks. The self-healing process is usually enclosed into a separate layer or components in ...

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 ...
