Cloud storage is an important milestone in the cloud computing industry and one of the security features that were introduced in cloud storage is via cryptographic methods to control the access only to authorized users. One of the known issues in cloud storage is the high key generation time for large-scale users and limiting the use of cryptography for data encryption. This problem can be overcome by using cryptography uses a single key, but another problem will arises is the potential for a single point of vulnerability if the key fell in the hands of unauthorized persons, then the whole secret and information can be compromised. The objectives of this study were to execute and analyze key generation times for large-scale users using the AES-256 method and Shamir's Secret Sharing Scheme, which both are still using a single key concept and prove Shamir’s Secret Sharing Scheme is more suitable for large-scale users. Further testing proves that Shamir's Secret Sharing Scheme is more appropriate for large-scale users covering key generation and thresholds to ensure data is completely secure.

Based on the results of the tests, it can be proved that Shamir's Secret Sharing Scheme provides key generation times faster than AES-256, and strengthen by the control of key threshold to ensure that the stored data is more secure.
