This paper proposes a new concept of the genetic robot which has its own robot genome, in which each chromosome consists of many genes that contribute to defining the robotpsilas personality. The large number of genes also allows for a highly complex system, however it becomes increasingly difficult and time-consuming to ensure reliability, variability and consistency for the robotpsilas personality while manually initializing values for the individual genes. To overcome this difficulty, this paper proposes an evolutionary algorithm for a genetic robotpsilas personality (EAGRP). EAGRP evolves a gene pool that customizes the robotpsilas genome so that it closely matches a simplified set of features desired by the user. It does this using several new techniques. It acts on a 2 dimensional individual upon which a new masking method, the Eliza-Meme scheme, is used to derive a plausible individual given the restricted preference settings desired by the user. The proposed crossover method allows reproduction for the 2-dimensional genome. Finally, the evaluation procedure for individuals is carried out in a virtual environment using tailored perception scenarios.

Sensor networks are resource-constrained, which makes developing efficient key distribution scheme a challenging problem. In general, many key distribution techniques are designed to address the trade-off between limited resources and security, no key distribution technique is ideal to all the scenarios where sensor networks are used. In this paper, we primarily focus on storage requirements of several key distribution schemes in sensor networks, and obtain their lower bounds on the amount of information each user has to keep secret by modeling the key distribution schemes with an information theoretic framework.

We investigate the impact of node capture attacks on the confidentiality and integrity of network traffic. We map the compromise of network traffic to the flow of current through an electric circuit and propose a metric for quantifying the vulnerability of the traffic using the circuit mapping. We compute the vulnerability metric as a function of the routing and the cryptographic protocols used to secure the network traffic. We formulate the minimum cost node capture attack problem as a nonlinear integer programming problem. Due to the NP-hardness of the minimization problem, we provide a greedy heuristic that approximates the minimum cost attack. We provide examples of node capture attacks using our vulnerability metric and show that the adversary can expend significantly less resources to compromise target traffic by exploiting information leakage from the routing and cryptographic protocols.

A key pre-distribution scheme is a method by which initially an off-line trusted authority T A distributes pieces of information among a set of users. Later, each member of a group of users can compute a common key for secure communication. In this paper we present a Keying Material Based Key Pre-distribution Scheme, i.e., a group of users, using secret information preloaded in their memory and some public information retrieved from a keying material server, can compute a common key. We first formally define the keying material based key pre-distribution scheme in terms of the entropy, and give lower bounds on the amount of information each user has to keep secret. Then, we describe its applications for sensor networks.

Bill Gates mentioned in Scientific America that robot will enter every home in ten year the same as personal computers have entered into almost every home in ten year. This project is to response to this trend, and to think about how robot can enhance learning, for example, robot can be as learning tools, teaching tools, learning companions, teaching partner, or some other models to enhance learning.

A Novel Quantitative Analysis Model for Information System Survivability Based on Conflict Analysis

This paper describes a novel quantitative analysis model for system survivability based on conflict analysis, which provides a direct-viewing survivable situation. Based on the three-dimensional state space of conflict, each player’s efficiency matrix on its credible motion set can be obtained. The player whose desire is the strongest in all initiates the moving and the overall state transition matrix of information system may be achieved. In addition, the process of modeling and stability analysis of conflict can be converted into a Markov analysis process, thus the obtained results with occurring probability of each feasible situation will help the players to quantitatively judge the probability of their pursuing situations in conflict. Compared with the existing methods which are limited to post-explanation of system’s survivable situation, the proposed model is relatively suitable for quantitatively analyzing and forecasting the future development situation of system survivability. The experimental results show that the model may be effectively applied to quantitative analysis for survivability. Moreover, there will be a good application prospect in practice.

Role-Based Access Control (RBAC) model is naturally suitable to organizations where users are assigned organizational roles with well-defined privileges. However, due to the large number of users in nowadays online services of organizations and enterprises, assigning users to roles is a tiresome task and maintaining user-role assignment up- to-date is costly and error-prone. Additionally, with the increasing number of users, RBAC may have problems in prohibiting cheat and changing roles of users. In order to categorize information and formulate security policies, human decision making is required which is naturally fuzzy in the real world. This leads using a fuzzy approach to address the issue in order to provide a more practical solution. In this paper, applicability of fuzzy set theory to RBAC has been investigated by identifying access control building blocks which are fuzzy in essence. An existing RBAC model is extended to allow imprecise access control policies, using the concept of trustworthiness which is fuzzy in nature. We call the extended model as Fuzzy RBAC. Applicability of the extended model has been evaluated through some case studies. © 2007 IEEE.

As a security principle, separation of duty (SoD) is widely considered in computer security. In the role-based access control(RBAC) model, separation of duty constraints enforce conflict of interest policies. There are two main types of separation of duty policies in RBAC, Static SoD (SSoD) and Dynamic SoD (DSoD). In RBAC, Statically Mutually Exclusive Role (SMER) constraints are used to enforce Static Separation of Duty policies. Dynamic Separation of duty policies, like SSoD policies, are intended to limit the permissions that are available to a user. However, DSoD policies differ from SSoD policies by the context in which these limitations are imposed. A DSoD policy limits the availability of the permissions over a users permission space by placing constraints on the roles that can be activated within or across a users sessions. Like SMER, in RBAC Dynamically Mutually Exclusive Role (DMER) constraints are used to enforce DSoD policies. We investigated using of a fuzzy approach to address the issue in order to provide a more practical solution. In this paper, we propose a model to express the separation of duty policies in RBAC using the fuzzy set theory. The concept of trustworthiness, which is fuzzy in nature, is used to express this model. In comparison with non-fuzzy methods, our method is more pragmatic and more consistent with the real world. The expressiveness of our method is higher than the nonfuzzy ones. We show expression of some constraints in our method which cannot be expressed by non-fuzzy methods. Applicability of the method is shown through an example of the real world. © 2007 IEEE.
