Lightweighted Security Algorithm Based Computer Network Security Storage System in Cloud Computing

The network storage security system is essential to secure the data transmission in the system that helps to maintain the privacy of the confidential data in the cloud computing. The existing models showed various techniques for the security the network storage security but did not attain the better results due to limited capability for withstanding the attacks in the network. To overcome the existing problem of network security storage against the vulnerable attacks and identification of unauthorized access in the network, an advanced cryptographic algorithm called Lightweighted Security Algorithm (LSA) is used for the encryption of data in the cloud to improve the Computer Network Security Storage System (CNSSS) in cloud computing for the minimization of computational resources. The LSA model generated the round keys for the expansion of key that boosted the security mechanism of the model. The extra key was generated by the LSA model after the authentication and verification in the key management phase. The developed LSA model has exhibited better results with minimum encryption time of 56.24ms for 5KB and decryption time of 27.53ms for 5KB compared to the existing traditional cryptographic models.
