Abstract
Purpose
The privacy of the information is a major challenge in the communication process. In the present modern generation, the cryptography plays a vital role in providing security for data, such as text, images and video while transmitting from source to destination through internet or intranet. The Rivest-Shamir-Adleman (RSA) is an asymmetric key cryptographic system, where the security of the method works on the strength of the key.
Design/methodology/approach
In an asymmetric key crypto system, a pair of keys is generated one public key for encryption and one private key for decryption. The major challenge of implementing the RSA is the power function which becomes tedious and time consuming as the exponential value increases. The Chinese remainder theorem proves to be the best for data encryption when it comes to execution time of the algorithm. The proposed novel RSA algorithm with lookup table (LUT) is an extension to the Chinese remainder algorithm, which works better for image and video in terms of time complexity.
Findings
This paper presents a LUT approach for implementing the RSA with a minimal processing time. The proposed algorithm was compared with the standard algorithms like, Chinese remainder theorem, binary approach and squared multiplication approach. As the size of the exponent value increases, the proposed method shows better performance compared to other standard methods.

Abstract
Purpose
The analysis focuses on the perspective of overall strategic fit in the supply chain of onion seed in Nepal. The purpose of this paper is to analyze current status of onion seed sector in Nepal from the perspective of selected functional strategies that fit in supply chain, and also identifies how various actors involved coordinate among each other.
Design/methodology/approach
The integrated approach has been used. It is an actor-oriented approach used to trace product flows. Supply chains generally include several actors for the onion seeds supply chain in Nepal, all those actors may or may not be applicable. However, initial approach would be to first look for these actors then subsequently identify existing supply and its actors. Some traditional methods of product and market analysis isolate operational costs along various stages of production. But, this paper used more comprehensive methodology that has taken into account an entire spectrum of associated activities and inputs.
Findings
Result revealed that the market actors of supply chain are taking significant benefit of value addition due to more investment in value creation. Vertical coordination is completely absent and the existence of horizontal coordination is in fragile form. The functional strategies in the upstream as well as the market side are not properly matching with the preference of the downstream actors of supply chain. It is suggested that the supply chain activities should work with different functional strategies such as proper drying and storage of seed and production of preferred varieties to satisfy the need of end consumers.
Research limitations/implications
It covers a single crop.
Originality/value
The findings and methodological discussions aim at providing practical guidance for supply chain researchers on how to analyze the strategic fit in supply chain.
