Binary rewriting and call interception for efficient runtime protection against buffer overflows

Buffer overflow vulnerabilities are one of the most commonly and widely exploited security vulnerabilities in programs. Most existing solutions for avoiding buffer overflows are either inadequate, inefficient or incompatible with existing code. In this paper, we present a novel approach for transparent and efficient runtime protection against buffer overflows. The approach is implemented by two tools: Type Information Extractor and Depositor (TIED) and LibsafePlus. TIED is first used on a binary executable or shared library file to extract type information from the debugging information inserted in the file by the compiler and reinsert it in the file as a data structure available at runtime. LibsafePlus is a shared library that is preloaded when the program is run. LibsafePlus intercepts unsafe C library calls such as strcpy and uses the type information made available by TIED at runtime to determine whether it would be ‘safe’ to carry out the operation. With our simple design we are able to protect most applications with a performance overhead of less than 10%. Copyright © 2006 John Wiley & Sons, Ltd.

Generalized Post Embedding Problems

The Regular Post Embedding Problem extended with partial (co)directness is shown decidable. This extends to universal and/or counting versions. It is also shown that combining directness and codirectness in Post Embedding problems leads to undecidability.

Analyzing the Impact of Bootstrapped ADC with Augmented NMOS Sleep Transistors Configuration on Performance Parameters

This paper represents an efficient bootstrapped analog to digital converter with augmented NMOS sleep transistors. The newly designed MOS-based bootstrapped circuit is implemented to provide controlled input supply for analog to digital converter to develop the enhancing capability of circuit. This will reduce the effective leakage of the circuit. In the second stage, the NMOS sleep transistors are augmented as pull-up and pull-down transistors. Due to augmentation of transistors, controlled power supply ( \(V_{\mathrm{DD}})\) is obtained. Because of this, current driving capability in MOS transistors is improved and minimum sub-threshold leakage current is formed. Due to this, reduction of leakage power dissipation occurs much effectively. The whole simulation has been done at 45 nm (nanometer) technology. It is realized that the leakage power is reduced till 50 % approximately and delay performance is improved. It means that speed is improved using bootstrapped circuit with augmented sleep transistors NMOS. In this paper, different consecutive designs with Analog to Digital converter are represented.     

Kriging Surrogate Based Multi-objective Optimization of Bulk Vinyl Acetate Polymerization with Branching

Despite the established superiority in finding the global as well as well-spread Pareto optimal (PO) points, the need of more numbers of function evaluations for population based evolutionary optimization techniques leads to a computationally demanding proposal. The case becomes more miserable if the function evaluations are carried out using a first principle based computationally expensive model, making the proposal not fit for online usage of the application. In this work, a Kriging based surrogate model has been proposed to replace a computationally expensive model to save execution time while performing an optimization task. A multi-objective optimization study has been carried out for the bulk vinyl acetate polymerization with long-chain branching using these surrogate as well as expensive models and Kriging PO solutions similar to those found by the first principle models are obtained with a close to 85% savings in function evaluations.

Exploring Blockchain and Smart Contract Technology for Reliable and Secure Land Registration and Record Management

The most significant issue in the government registry department is the duplicate registry of land in the current scenario. These kinds of problems are increasing day by day by day, which necessitates the advancement of the existing registry process system. It is a manual process that a typical stamp-based or newly not secure online process (only a few places). Use of a manual process, there are many issues in the duplicate registry of a particular land. The final registry, where the landlord has a stamp paper copy and sale deed or a specific number of the property. One receipt copy at the land registry department for their record. Blockchain has emerged as a new technology to resolve or handle the above-said issue of the current system, a distributed ledger that is a timestamp and immutable. Being immutable, forgeries related to the particular land during the registry are not allowed. This concept provides trust and consensus among all entities in the network or system. In this paper, we propose a framework for automated maintains a record of registry papers. This framework will also resolve the most effort to loan clearance operations and provide transparency in government e-governance. The system handled by the blockchain network, instead of existing typical manual processor online registry record maintain the process, it includes: An authentication scheme at multiple levels to make the blockchain-based framework secure, a quick verification for all the stack holders (bank, registry department, buyer, and seller), and apply Smart Contract to automate check the loan process as government norms and facilitate buyer and seller selling and purchase. The obtained consequences are examined against the latest approaches to indicate the supremacy of the proposed framework and provide transparent, accountable, incoherent data with the different government departments.
