Protein Motifs to Hide GA-Based Encrypted Data

Algorithm 2

Key-Generating Algorithm.

	Input: K.
	Output: Key.//generated key
	Begin
(1)	divide Key(K, K1, K2); //divide K into two divisions k1 and k2
(2)	For i = 1 to 2 do
	{
	L[i] = length(Ki);
	For j = 1 to L[i] do
	{
	if (i =  = 1) then
	{
	dec_key1[j] = char_to_decimal(ascii(K[j]));
	new_key1[ L-(j-1) ] = dec_key1[j] – 1;
	}//if
	else {
	dec_key2[j] = char_to_decimal(ascii(K[j]));
	new_key2[j] = dec_key2[j] –(2 j);
	}//else
	}//for j
	}//for i
	k = 1;
(3)	for i = 1 to L [1] do
	for j = 1 to L [2] do
	{
	M = new_key1[i] new_key2[j];
	If (M > 256) then M = M mod 256;
	key[k] = decimal_to_binary(ascii(M) );
	k = k+1;
	}//for
	Return Key;
