"Diawali dengan Google File System dan MapReduce dari Google, Apache mengenalkan Hadoop sebagai teknologi pengolah data yang berukuran sangat besar. Karena tujuan awal Hadoop hanya untuk mengolah data yang berukuran besar, masalah keamanan data belum diantisipasi pada Hadoop versi 1.2.1. Pada skripsi ini membahas tentang program enkripsi yang dijalankan pada Hadoop versi 1.2.1. Program mengenkripsi file teks yang ada pada Hadoop Distributed File System(HDFS) dengan cara mengenkripsi setiap kata yang ada pada file. Program menggunakan algoritma enkripsi AES dan DES. Skripsi ini juga membandingkan program enkripsi yang berjalan tanpa Hadoop, Hadoop Standalone, dan Hadoop Distributed. Pada Hadoop Distributed menggunakan dua komputer dan satu virtual komputer. Melalui percobaan, terlihat bahwa program yang berjalan tanpa Hadoop memiliki troughput 0.99 MB/s sedangkan program yang berjalan pada Hadoop Standalone dan Hadoop Distributed masing-masing sebesar 0.53 MB/s dan 0.65 MB/s.

Beginning with the Google File System and MapReduce from Google, Apache introduce Hadoop as large data processing technology. Since the initial purpose of Hadoop for large data processing, data security issues have not been anticipated in the Hadoop version 1.2.1. In this final project discusses encryption programs that run on Hadoop version 1.2.1. The program encrypts text files that exist on the Hadoop Distributed File System (HDFS) by means of encrypting every word in the file. The program uses AES and DES encryption algorithm. This final project also compare the encryption program that runs without Hadoop, Hadoop Standalone, and Distributed Hadoop. Through experiments, it appears that the program is running without Hadoop having throughput 0.99 MB/s while the program is running on Hadoop Standalone and the Hadoop Distributed respectively 0.53 MB/s and 0.65 MB/s."

"Tuttavia, l’analisi di sicurezza di questi schemi crittografici (fino ai primi anni ‘80) era soprattutto guidata dall’intuito e dall’esperienza. Nuovi schemi venivano ideati e, dopo qualche tempo, inevitabilmente, un nuovo attacco alla sicurezza veniva scoperto. Il paradigma della “sicurezza dimostrabile” ha trasformato la crittografia da arte a scienza, introducendo un paradigma for male per l’analisi di sicurezza dei crittosistemi: in questo modo è possibile fornire una dimostrazione matematica che un dato sistema è sicuro rispetto ad una classe generale di attaccanti. Tanto più vasta e vicina alla realtà è que sta classe, tanto più forti sono le garanzie offerte dal crittosistema analizzato."

"Dalam komunikasi data, dengan meningkatnya jumlah dan keparahan serangan ancaman cyber harian, enkripsi menjadi salah satu alat penting untuk memastikan keamanan data dalam perjalanan. Meskipun AES, terutama AES-256, saat  ini  dianggap  sebagai  penerus  DES  yang  dapat  memberikan  keamanan tersebut, itu tidak akan tetap menjadi status quo. Dengan kemajuan penelitian komputasi kuantum, keamanan  yang diberikan  oleh AES tidak  akan  bertahan lama. Dengan demikian, penelitian untuk enkripsi berbasis chaotic map, Chaotic Encryption Standard (CES) pada akhirnya akan menjadi kandidat prospektif untuk penerus AES. Namun demikian, metode enkripsi seperti CES tidak hanya perlu tahan terhadap upaya cracking, tetapi juga harus mempertahankan informasi yang tersimpan di dalamnya saat sedang ditransfer. Dalam percobaan ini, aliran data yang dienkripsi dalam CES, dalam hal ini CES (PCMPB/K), dibandingkan dengan yang dienkripsi dalam AES-256 dan DES. Semua dijalankan melalui simulasi NS3 dengan jaringan tidak bebas-kesalahan menggunakan UDP sebagai enkapsulasi paket. Hasil percobaan menunjukkan bahwa meskipun CES (PCMPB/K) memang lebih sulit untuk di rusak daripada AES256 dan DES, hal tersebut itu menimbulkan risiko yang lebih tinggi untuk tidak dapat dibaca dalam jaringan tidak bebas-kesalahan karena ukuran bit blok besar yaitu 16 kali dari AES-256 dan 32 kali DES.

In data communication, with increasing number and severity of day to day cyber-threat attacks, encryption becomes one of the crucial tools to ensure the security of data in transit.   Although AES, especially AES-256, currently considered as the successor of DES that can give such security, it will not remain a status quo. With the advancements of quantum computing research, the security provided by AES is not going to stand for long. Thus, the research for chaotic map-based  encryption,  Chaotic  Encryption  Standard  (CES)  will  eventually become  prospective  candidate  for  AES  successor.  Nevertheless,  encryption method like CES not only needs to be resistant to cracking effort, but it also has to retain the information held within while being transferred.   In this experiment, streams of data encrypted in CES, in this case CES(PMCS/E), is compared to the ones encrypted in AES-256 and DES. All are run through an NS3 simulation with non-error free network using UDP as packet encapsulation. The results of the experiment show that even though CES(PMCS/E) is indeed harder to crack than AES256 and DES,   it poses higher risk to be unreadable in a non-error free network due to the large block bit size which is 16 times of the AES-256 and 32 times of the DES."

"Sistem kripto (data encryption) dengan kunci publik, mempunyai keunggulan dalam pengaturan kunci dibanding dengan sistem kripto yang konvensional. Pada sistem kripto konvensional, suatu jaringan komputer dengan n riser dibutuhkan n(n-1)2 kunci, sedangkan pada sistem kripto dengan kunci publik ini hanya dibutuhkan n kunci. Di samping mempunyai keunggulan pada pengaturan kunci, sistem kripto dengan kunci publik ini menjamin keaslian pesan yang dikirimkan oleh seorang user. Sistem kripto dengan kunci publik ini dapat pula diaplikasikan untuk pembuatan skema pemeriksaan keaslian password. Salah satu keunggulan skema pemeriksaan keaslian password dengan dasar sistem ini mampu mempertahankan keamanan sistem walaupun berkas yang berisi password-password user berhasil diketahui. Salah satu alasannya adalah derajat kesulitan untuk menurunkan password-password yang sebenarnya relatif tinggi."
