Physics news on Phys.org
A friend gave it to me.
 
I don't know where he got it.
He just said if I can decrypt but didn't give me any clues.
 
It looks like binary, I tried the ASCII chart but gave me more numbers,
it could be ternary or another base.
 
I did a google search on the first three bytes and got this crazy Facebook account

https://www.facebook.com/01100001-01100100-01101000-01100101-01101001-01110010-1421042178127360/timeline/
 
It doesn't look like English, and my friend is white.
 
I got a string of numbers
43 49 43 41 44 41 20 33 33 30 31
 
Perhaps if you "decode" via ASCII again the result will make some kind of sense to you (if not then try google what you find).
 
I got this in the second layer

Base16: CICADA 3301

Possible, but since the only digits present are 0 and 1, it's most likely binary and not ternary or some other base.

The CICADA part seems promising...

Groups 3,6,9,12... are encoded directly in ASCII, 00100000=(20h), the Space character in the above string.
Other groups are paired such that they are the ASCII encoding of the Hex digits of an ASCII character. The first character is:
00110100 > ASCII '4'
00110011 > ASCII '3'
= 43h
= 'C' in ASCII
Then followed by a Space. (00100000 > 20h)

If you represent the Space character as "_" the message reads: C_AI_C_A_D_A__3_3_0_1 (note the two spaces before the first "3")

Edit: fixed second character in decode: was 'A' should be 'I'.

You're off a bit. The second letter comes from groups 4 and 5, which are 34 and 39 (in hex) which are the ASCII codes for 4 and 9 (decimal). As a hex number, 0x49 is the ASCII code for I (upper case i). The OP reported this in post #16.

Oops! You are right. Post has been fixed. Thanks!
 
My friend gave me the answer and it it CICADA 3301.
He said that he wants to be part of the secret organization.
