Cryptography involves different cryptographic algorithm that contributes in the security purpose of the programs. The cryptography algorithms are divided into two parts symmetric and asymmetric. There are many different challenges to implement cryptography algorithm specially throughput in terms of time execution. So, it is important that it runs with minimum encryption and decryption time and hence improvise the time efficiency. In this paper, we study and analyze the performance of different cryptographic algorithm on multicore processors and also we explore the performance in sequential and parallel implementation of cryptography algorithm on multi core processors. In this review paper we have given the summary of different research papers on cryptography and briefed about some cryptographic tools.
Antibiotics are marvelous drugs. They fight against various infectious diseases and saved millions of lives. However the recent failure of antibiotics due to drug resistant pathogens and rapid spread of new infections, pressurize the health organizations and pharmaceutical industries to change their strategy and stop going slow growing production of more synthetic antibiotics against the fast growing antibiotic resistant organisms. There are considerable alternative sources of natural antimicrobials from plant with different mode of actions and was found to have competitive effects compared to commercial antibiotics. This reviews shows the plant derived antimicrobials as alternative source for synthetic antimicrobials.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
