Workshop on Cryptographic Hardware and Embedded Systems (CHES) is a workshop for cryptography research, focusing on the implementation of cryptographic algorithm. The two general areas treated are the efficient and the secure implementation of algorithms. Related topics such as random number generators, physical unclonable function or special-purpose cryptanalytical machines are also commonly covered at the workshop. CHES is sponsored by the International Association for Cryptologic Research. It was first held in Worcester, Massachusetts in 1999 at Worcester Polytechnic Institute (WPI). It was founded by Çetin Kaya Koç and Christof Paar. CHES 2000 was also held at WPI; after that, the conference has been held at various locations worldwide, including in chronological order Paris, San Francisco, Cologne, Boston, Edinburgh, Yokohama, Vienna, Washington, D.C., Lausanne, Santa Barbara, Nara, Leuven, and again Santa Barbara. In the last few years, CHES had between 300-400 participants, making it one of the largest events in the academic cryptography community.
[Chorus]I come and go like a boomerang,
Set me free and ill come back again.
To and fro like a freight train,
Stop and lend yo time again.
Verse 1
I'm dark in a place,
stuck in outer space,
talkin to my friends they dont know what i say.
I'm in the ocean duck divin the waves,
I'm on a mountain been climbin for days.
"The top of the world is just up the way",
said the blind man wavin the sage.
Chapter 5, 29th page
Time ain't the only thing movin today.
I gotta go, gotta get away,
Let the sunset just set away.
On the deck tryin to catch a wave,
some girl in a dress will say,
"Please don't leave me" [x2]
[chorus]
Verse 2
Stop and go, is this rock and roll?
Soul brotha on the yellow brick road.
Dressed up ready to go,
with my hair messed up in some regular clothes.
Guess what, i'm strikin a pose,
you could make a statue i suppose.
Lights, camera, then i froze,
Thoughts of you and my head arose.
She loves me like a pedal on a rose,
I love alot, last pedal on the floor.
On the deck tryin to catch a wave,
some girl in a dress will say,
"Please don't leave me" [x2]
[chorus]
woah oh, oh, oh, ooh
Verse 3
Believe me this time i'm leavin,
for a little bit longer than a weekend.
And when you see me ill be rockin,
on yo tv, i know your watchin.
And ill be thinking of you often,
put the top down and see a rose blossom.
On the deck tryin to catch a wave,
some girl in a dress will say,
"Please don't leave me" [x2]
