Hi. i want to generate 16 sub keys .Algorithm is as follows
K=[k1, k2, k3, k4]%initial key and are points on elliptic curve.
for first key,
k5=2*k4+k1
k6=k5+k2
k7=k6+k3
k8=k7+k4
K1=dec2bin[k5 k6 k7 k8]
similarly i have to generate 16 subkeys. Multiplication and addition is of elliptic curve addition and multiplication.
a=0;
b=17;
n=313;
A=[[36 6]; [117 3] ;[198 310] ;[68 86]];
k=size(A,1);
B=zeros(size(A))
temp=A(k,:)
A4=multell(temp,2,a,b,n);
A5=addell(A4,A(k-3,:),a,b,n);
A6=addell(A5,A(k-2,:),a,b,n);
A7=addell(A6,A(k-1,:),a,b,n);
%temp(A(k+1),:)
B=[A4 A5 A6 A7];
B1=dec2bin(B)
key1=reshape(B1,1,64)

#Edited
k=cell(1,8);
k{1}=[36 6];
k{2}=[117 3];
k{3}=[198 310];
k{4}=[68 86];
for i=5:8
k{i}=2*k{i-1}+k{i-4};
end
