Abstract

Cloud adalah teknologi populer yang memungkinkan untuk mengakses data melalui Internet yang bahkan dapat menyimpan data sebagai pengganti penyimpanan lokal. Cloud memungkinkan pengguna untuk menyimpan data mereka di cloud tanpa perlu khawatir akan keakuratan dan keandalannya. Namun menyimpan data di cloud menimbulkan tantangan keamanan tertentu. Mengalihdayakan data di cloud menyebabkan pemilik data kehilangan kontrol fisik atas data mereka. Penyedia Layanan Cloud tertentu dapat mengakses data dari cloud secara tidak legal dan menjualnya kepada pihak ketiga untuk mendapatkan keuntungan. Jadi, meskipun outsourcing data di cloud tidak mahal dan mengurangi kompleksitas penyimpanan dan pemeliharaan berdurasi lama, setidaknya ada jaminan integritas data, privasi, keamanan, dan ketersediaan di server cloud. Tugas Akhir ini akan berfokus pada strategi verifikasi integritas untuk data outsourcing. Skema yang diusulkan adalah menggabungkan mekanisme enkripsi dengan verifikasi integritas. Skema enkripsi yang digunakan di sini adalah algoritma kriptografi AES-256 dan fungsi hash SHA-256 yang digunakan untuk memastikan kebenaran penyimpanan data pada server yang tidak terpercaya.

Cloud computing is a popular technology which permits storing and accessing data over Internet instead of storing it on local machine’s hard drive. Cloud enables users to store their data on cloud without fearing about its accuracy and reliability. However storing data on cloud imposes certain security challenges. Outsourcing data in cloud result in data owners losing physical control over their data. Certain Cloud Service Providers may operate dishonestly with the cloud users’ data, they may sneak the data from cloud and sell it to third parties in order to earn profit. Thus even though outsourcing data on cloud is inexpensive and reduces long duration storage and maintenance complexity, there is least assurance of data integrity, privacy, security and availability on cloud servers. A number of solutions have been recommended to solve the security issues in cloud. This undergraduate thesis focuses on the integrity verification strategy for outsourced data. The proposed scheme combines the encrypting mechanism along with integrity verification strategy. The encrypting scheme used here is cryptographic algorithm like AES-256 and SHA-256 hash function is employed for ensuring data storage correctness on untrusted server.
