| Abstract | It is no secret that modern computer systems are vulnerable to threats such as side-channel attack or reverse engineering whereby sensitive data or code could be unintentionally leaked to an adversary. It is the premise of this work that the mitigation of such security threats can be achieved by leveraging the inherent complexity of emerging chaos-based computing (computer systems built from chaotic oscillators). More specifically, this paper considers a chaos-based arithmetic logic unit which consists of many unique implementations for each possible operation. Generalizing to a chaos-based computer, a large number of implementations per operation can enable the obfuscation of critical code or data. In such a system, any two functionally equivalent operations are unique in terms of control parameters, power profiles, and so on. Furthermore, many possible implementations for each operational code can be leveraged to compile a program that is uniquely defined in terms of what the user knows -- such knowledge which itself could be protected via encryption. The frequencies of the various operations are shown to approach that of a probabilistic system as the circuit is allowed to evolve in time. Further, the difficulty of a successful attack is assumed to be directly related to the number of unique op-code sets possible which is shown to grow exponentially with allowed evolution time for the proposed chaos-based arithmetic logic unit. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
