2.2 Secure Compilation to Modern
Pieter Agten , Raoul Strackx, Bart Jacobs and Frank Piessens define that We are present a secure (fully abstract) compilation
scheme to compile associate object-based problem-oriented language to low-level machine language.
Full abstraction is achieved by wishing on a fine-grained program counter-based operation protection scheme , that is an
element of our low-level target language. We discuss why customary compilers fail to supply full abstraction and introduce
enhancements required to realize this goal.
We prove that our increased compilation theme provides full abstraction from our high-level linguistic communicationtoour
low-level target language. Lastly, we have a tendency to show by suggests that of a model implementation that our low-level
language with fine-grained memory access management will be accomplished withefficiencyontrendycommodityplatforms.

6. MD5 Algorrithm:
MD5 uses a buffer that is made up of four words that are each 32 bits long. These words are called A, B, C and D.
They are initialized as:
word A: 01 23 45 67
word B: 89 ab cd ef
word C: fe dc ba 98
word D: 76 54 32 10

MD5 further uses a table K that has 64 elements. Element number i is indicated as Ki. The table is computed beforehand to
speed up the computations. The elements are computed using the mathematical sin function:
Ki = abs(sin(i + 1)) * 232
Four auxiliary functions:
In addition MD5 uses four auxiliary functions that each take as input three 32-bit words and produce as output one 32-bit
word. They apply the logical operators and, or, not and xor to the input bits.
 F(X,Y,Z) = (X and Y) or (not(X) and Z)
 G(X,Y,Z) = (X and Z) or (Y and not(Z))
 H(X,Y,Z) = X xor Y xor Z
 I(X,Y,Z) = Y xor (X or not(Z))
Processing the blocks:
The contents of the four buffers (A, B, C and D) are now mixed with the words of the input, using thefourauxiliaryfunctions(F,
G, H and I). There are four rounds, each involves 16 basic operations. One operation is illustrated in the figure below.
Fig:3 MD5

One operation performed in a round of the MD5 function.The figure shows how the auxiliary function F is applied to the four
buffers (A, B, C and D), using message word Mi and constant Ki. The item "<<<s" denotes a binary left shift by s bits.
The output:
After all rounds have been performed, the buffers A, B, C and D contain the MD5 digest of the original input.
