Data security is a very important compilation using cloud computing; one of the research that is running and using cloud technology as a means of storage is G-Connect. One of the developments made by the G-Connect project is about data security; most of the problems verification of the data sent. In previous studies, Keccak and RSA algorithms have implemented for data verification needs. But after a literature study of other algorithms that can make digital signatures, we found what is meant by an algorithm that is better than RSA in rectangular speeds, namely Digital Signature Algorithm (DSA).DSA is one of the key algorithms used for digital signatures, but because DSA still uses Secure Hash Algorithm (SHA-1) as an algorithm for hashes, DSA rarely used for data security purposes, so Keccak is used instead of the hash algorithm on DSA. Now, Keccak become the standard for the new SHA-3 hash function algorithm. Because of the above problems, the focus of this research is about data verification using Keccak and DSA. The results of the research are proven that Keccak can run on DSA work system, obtained a comparison of execution time process between DSA and RSA where both use Keccak.

Data security in the cloud continues to be a huge concern. The adoption of cloud services continues to increase with more businesses transitioning from on premise technology infrastructures to outsourcing cloud-based infrastructures. As the cloud becomes more popular, users are increasingly demanding control over critical security elements of the data and technology assets that are in the cloud. In addition, there are still cries for greater data and security in the cloud. The goal of this paper is to provide cloud service users with greater control over data security in the cloud while at the same time optimizing overall security in the multi-tenant cloud computing environment. This paper introduces cloud-based intelligent agents that are configurable by the users and are expected to give greater compliance for data security in any of the cloud service models.

Masalah Keamanan merupakan salah satu aspek penting dari sistem informasi. Begitu pentingnya nilai informasi menyebabkan seringkali informasi diinginkan oleh orang tertentu kemudian dapat memodifikasi informasi tersebut. Untuk dapat mengesahkan informasi yang didapatkan, maka harus dilakukan authentication pada informasi sehingga diketahui keaslian informasi. Dalam penelitian ini diimplementasikan suatu metode secure hash algorithm-1, sehingga penerima informasi dapat mengetahui adanya perubahan terhadap data penting yang diterima dari pihak lain. Metode ini mampu membangkitkan nilai hash dari sebuah string atau file. Dengan perubahan sekecil apapun pada informasi yang diterima, dapat diketahui keasliannya. Secure Hash Algorithm adalah fungsi hash yang bekerja satu arah, ini berarti pesan yang sudah diubah menjadi message digest tidak dapat dikembalikan menjadi pesan semula. Dua pesan yang berbeda akan selalu menghasilkan nilai hash yang berbeda pula. Hasil rancangan perangkat lunak ini dengan input panjang string yang berbeda akan menghasilkan output dengan panjang string tetap yaitu 160 bit, yang dapat dibuat dalam bentuk library pada pemrograman java sehingga dapat langsung digunakan untuk proses otentikasi dan keamanan data.Security problem is one of the important aspects of the information system. Once the importance of the value of information causes information is often desired by a particular person can then modify that information. To be able to certify that the information obtained, it must be done so that the authentication on the information known to the authenticity of the information. In this study implemented a method of secure hash algorithm-1, so that the recipient can know the information of changes to important data received from the other party. This method is able to generate a hash value from a string or file. With the slightest change to the information received, it is known authenticity. Secure Hash Algorithm is a hash function that works in one direction, this means that the message has been converted into a message digest can not be restored to its original message. Two different messages will always produce a different hash value. Software design results with different input string length would produce output with fixed string length is 160 bits, which can be made in the form of the Java programming library that can be directly used for authentication and data security.

Cloud computing is an evolving computing technology that provides many services such as software and storage. With the introduction of cloud storage, the security of outsourced data has become a major issue in cloud computing. Data storage in cloud computing environment needs to be secured in order to provide a safe and foolproof security for data outsourcing of the cloud service users. This paper presents a model for security of data in public cloud storage environment which successfully detects the unauthenticated access or any anomaly in the data. The proposed authentication model along with the data security model presented in this paper shows that this model is the best model suitable for securing the data in cloud computing environment
