“…As for key protection aspect, a multilevel threshold secret sharing scheme [13] is conducted by duplicating the secret key and then distributing into multiple resource providers to ensure availability. Moreover, key-insulated symmetric cryptography [8] is presented to against the compromise of keys from software-based attack such as malware.…”

“…Although, there are some researchs using the threshold cryptography to provide security for key stored on cloud [10][11][12][13][14], there are no researches attempting to find a suitable threshold for any number of shares distributed. The objective of this paper is, therefore to design and implement a method that is able to assist in finding such values.…”

The objective of using threshold cryptography on cloud environment is to protect the keys, which are the most important elements in cryptographic systems. Threshold cryptography works by dividing the private key to a number of shares, according to the number of virtual machines, then distributing them each share to each virtual machine. In order to generate the key back, not all the shares are needed. Howerver, the problem is that there has been no research attemping to find a suitable threshold value for key reconstruction. Therefore, this paper presented a guildline designed and implemented that can assist to choose such value. The experiment was setup using CloudSim to simulate cloud environment and collecting time taken in key distribution and key reconstruction process to achieve the optimal threshold value.

“…Communication model of the proposed scheme somehow matches with [5], [7] but proposed scheme is more secure and take care both type of problems namely, data splitting and key shares in smart manner to provide better security. In this paper the proposed scheme keeps data and keys at different clouds and treat them differently.…”

In the period of revolutionary change in information technology, the two developments that are most far-reaching have been cloud computing and the mobile Internet. These two information technology revolutions diverge in mobile cloud computing. There are already immense risks with data hosted in-house, so it's no secret that data offsite sits at even higher risk. With Data on offsite, higher avenues for attack and the fact that it will be traveling more makes it easier to be hijacked. With the technology regularly improving, there are ways to make sure of greater security. However with technology regularly improving, there are always people out there lifting their hacking skills.An effective methodology with prominent features of data integrity and confidentiality is proposed here to ensure the safety of offsite data or the data on cloud. In this paper we propose the mechanism which uses the concepts of ECC algorithm, Shamir's secret key sharing algorithm along with distinct cryptography tools such as threshold cryptography that enhances the security of data stored on clouds.
