ABOUT ME

Hi Guys. Thank you for visiting my simple blog. A Blog that is dedicated to any of you who wants to learn embedded cryptography, a part of applied cryptography engineering which bridges cryptography and electronics devices as well as discussing how to make an electronic cipher machine. I said this topic is really nice and I hope you enjoy it too. In addition, this blog covers various implementation of cryptographic and hash algorithm in discrete logic components and PIC microcontroller and hopefully in the future will also provide implementation on AVR, CPLD, FPGA, MIPS and ARM platform.

Now, let me introduce my self. My name is Edi Permadi. I was born 22 years ago in a village located approximately in the middle of the Banjar Patroman City and the Pangandaran Beach. Both my parents are teacher. One teaches elementary school and the other teaches junior high school, they are Oom Rohimah, S.Pd and Darsono Gunawijaya S.Pd. Thanks mom and dad, both of you are cool and inspiring. I am proud to be your son.

I experienced my childhood in a happy and warm family like other children. I started becoming a geek since I was in the fourth year of my elementary level. At that moment, I started to love skimming and reading books and watching my dead while fixing electrical stuff. Two years later, my uncle gave me a book entitled “Vademekum Elektronika” that authored by Wasito S., the first book that introduced me to electronics. Since that, I started to assemble various circuits and learned to reverse engineering built circuit into schematics. That was unforgettable moment.

My “digital life” has been started since senior high school, when I entered a vocational high school named SMAK Bogor (Sekolah Menengah Analis Kimia Bogor) in 2001 for four years. At that moment I learned chemical much, started to use windows and trained to be analytical. However, I can not run away from electronics at that moment. Fortunately, I met a lot of helpful and kind students of IPB (Institut Pertanian Bogor a.k.a Bogor Agricultural Institute) and University of Pakuan. They taught me digital systems using discrete logic components. In the third year of my senior high school, I started to learn and use PIC microcontroller by reading and hands on practices. In the fourth year, I met a fat guy from IPB that introduced me to cryptography, a topic that was totally new for me. That was a hard moment for me, the time that I spent most of my time to learn cryptography from zero.

Fortunately, god gave me a chance to enter President University as full MT (Management Trainee) scholarship at 2005. At the beginning of my university life, I learned digital system and followed by microcontroller interfacing, digital laboratory and analog Laboratory in the other semester. Consequently, I tried to mix my knowledge on digital electronics and cryptography into embedded cryptography. A part of cryptography engineering that discusses the implementation cryptographic algorithm in electronics devices. Embedded cryptography is a wonderful topic to study, and it has becoming my passion.

After doing lots of practices, I finally decided to write my own blog, the blog that you are reading now, as a facility to share things that I have done. That was the short history of my life. Now, I am enjoying my life, doing independent research on embedded cryptography that mainly focuses on learning algorithm, implementing algorithm and tweaking implementation performance.

I realized that I can not stand without helps from many friends, teachers and lecturers. Here, I would like to express my deepest thanks to all beloved lecturers: DR. Zaki Suud, Ir. Achmad Fuad Mas’ud,M.Sc, DR. Erwin Sitompul, Hendra Tarigan, MS, DR. Oki Neswan, Ir. Carolus Kaswandi and all my friends in School of Electrical Engineering of President University. Not only that, I also want to express thanks to my friends at STSN (Sekolah Tinggi Sandi Negara), IPB (Institut Pernatian Bogor), Pakuan University and all my dear friends at SMAK Bogor. Guys, I’m nothing without you.

If you guys have some suggestion or question regarding any material stated on this blog, feel free and do not hesitate to ask me by sending email or leaving comments. I’ll appreciate your enthusiasm. Happy coding and have a nice day, wish you all the best.

Now, i’m about doing my final project to pursue my bachelor degree on Electrical Engineering. The topic is about applied embedded cryptography, which is PSTN crypto phone. A crypto phone is basically an electronic device to provide secure communication over PSTN line. The secure communication channel is provided by encapsulating digitally encoded voice using certain cryptographic algorithm.
