"Skripsi ini berisi mengenai konsep dasar, perancangan dan implementasi enkripsi data dengan RSA yang diterapkan pada private cloud Infrastucture as a Service (IaaS). Tujuan dari skripsi ini menganalisa keamanan pengiriman data dan waktu dari implementasi kriptografi RSA pada sistem Eucalyptus private cloud. Pengiriman data pada sistem virtualisasi private cloud membutuhkan enkripsi untuk mengantisipasi serangan dari man-in-the-middle sehingga penyerang tidak mengetahui isi data dengan mudah. Hasil penelitian menunjukkan bahwa waktu eksekusi program RSA dipengaruhi oleh ukuran data dan nilai kunci RSA yang dibangkitkan. Peningkatan ukuran data akan mempengaruhi peningkatan waktu eksekusi program RSA. Peningkatan waktu eksekusi untuk format .txt sebesar 31,44%, untuk format .doc sebesar 24,83% dan untuk format .pdf sebesar 24,85%. Nilai d untuk kunci privat RSA yang besar akan sangat mempengaruhi waktu eksekusi karena membutuhkan waktu dekripsi yang lebih lama. Sedangkan nilai e yang besar untuk kunci publik RSA tidak terlalu signifikan mempengaruhi waktu enkripsi menjadi lebih lama namun tetap berkontribusi terhadap waktu eksekusi RSA. Keamanan pengiriman data pada sistem private cloud dibutuhkan terutama dengan RSA 2048 bit dan sistem padding, namun pada skripsi ini hanya digunakan enkripsi plain RSA.

This thesis contains about fundamental concept, the design and the implementation of data encryption using RSA which is applied on private cloud Infrastucture as a Service (IaaS). The purposes of this thesis are to analyze the the data transfer security and the time of RSA cryptography appliance on Eucalyptus private cloud system. Secret data transfer on private cloud virtualization requires encryption in order to anticipated the attack from man-in-the-middle so that the attacker won?t know the contents of data easily.

The result of this research prove that RSA execution time influented by the size of data and the value of the generated RSA keys. Data size increment will influence the execution times of RSA. The increment time for .txt is 31,44%, increment time for .doc is 24,83%, and increment time for .pdf is 24,85%. Large values of d for RSA private key greatly affect the execution time because need a longer decryption time.

However, the large value of e for public keys isn?t influence the encryption time significantly but still contributes the execution time. The security of data transfer on private cloud system is needed especially using RSA 2048 bit and padding system appliance,however this thesis only implement plain RSA encryption."

""The first chapter gives an overview of cloud computing at a level accessible to a lay person. To motivate the reasons for a paradigm shift in the way we compute and store information, we introduce the concept of network-centric computing and network-centric content. A brief discussion of peer-to-peer systems, a first step in the shift from local to remote data storage and processing follows. The chapter continues with a discussion of technological advances that have made cloud computing possible and of the economical reasons why this new paradigm is attractive for many users and applications. Then we take a closer look at the cloud computing delivery models, Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). SaaS gives the users capability to use applications supplied by the service provider but allows no control of the platform or the infrastructure. PaaS gives the capability to deploy consumer-created or acquired applications using programming languages and tools supported by the provider. IaaS allows the user to deploy and run arbitrary software, which can include operating systems and applications. The new paradigm raises ethical questions and has significant vulnerabilities each dissected in separate sections. Finally, the chapter presents the major challenges faced by this new paradigm. The chapter concludes with a overview of the literature and with a historic perspective"--"

"Cloud computing adalah sebuah paradigma komputasi yang berkembang dari teknologi yang ada, seperti grid computing, virtualisasi dan Internet. Cloud computing memberi ilusi sumberdaya komputasi yang tak terhingga, yang dapat diakses dari mana saja, kapan saja. Meskipun cloud computing berpotensi memberikan manfaat yang besar, namun masalah keamananya masih menjadi pertanyaan, yang mana menghambat adopsinya. Persoalan keamanan pada cloud computing menjadi semakin rumit karena karakteristik cloud computing yang khas seperti kelenturan alokasi sumberdaya, dan pengguna yang jamak. Jaringan cloud berbasis platform Eucalyptus banyak diterapkan pada fasilitas cloud privat. Penelitian ini bertujuan untuk mengetahui potensi hambatan atas pelayanan jaringan cloud akibat serangan yang terarah (targeted attack), pada sistem jaringan cloud berbasis platform Eucalyptus. Pengujian menunjukan adanya peningkatan waktu respon hingga 2863,22% akibat serangan terarah terhadap layanan web administrasi. Penerapan pembatasan dan kendali laju data (rate control, rate limit) pada penelitian ini merupakan solusi untuk mengurangi dampak serangan terarah. Dengan langkah mitigasi ini peningkatan beban dapat dikendalikan sehingga tidak memengaruhi pelayanan. Pengujian kerentanan menunjukan layanan jaringan cloud berbasis platform Eucalyptus tidak memiliki ancaman kerentanan yang berpotensi menjadi serangan keamanan.

Cloud computing is a computing paradigm that evolve from existing technology, such as grid computing, virtualization and the Internet. Cloud computing provides an illusion of unlimited computing resources, which can be accessed from anywhere, anytime. Despite the potential gains achieved from the cloud computing, the model security is still questionable which hindered adoption. The security problem becomes more complicated under the cloud model as new dimensions have entered into the problem scope related to the model architecture, multi-tenancy, elasticity, and layers dependency stack.

Eucalyptus based cloud network service widely deployed as private cloud infrastructure. Experiment on this paper focused on finding potential denial-ofservice (DoS) and the impact on ability to provide services during attack. We observe an increase on response time up to 2863,22% during targeted attack to the web-based management service.

Mitigation effort by implementing rate control and rate limit on cloud controller help on reducing average system load to an acceptable level, which prevents disruption of the service. Vulnerability testing in this research shows that Eucalyptus web-based management does not have exploitable security hole."
