How to Prevent Correlation Power Analysis Attack on AES? Which techniques could be applied to AES to prevent these kind of attacks?

I can just think of creating noise with a parallel process for random computation, so the signals have the combination of that process and the crypto process.
DPA-resistant cores
Masking (attempt to conceal the intermediate date processed by modifying the data such that the complete secret is never processed simultaneously)


For example you can introduce s-box shuffling in AES as a software solution to decrease the likelihood that the attack succeeds.

 
Pseudo Code s-box shuffling from Figure 2 of www.indjst.org/index.php/indjst/article/download/61626/48132:

Begin
// The assignment of Round Key
Byte RK[11][16]
// The generation of Random Value
shuffle = rand()%8
// The execution of Key Expansion
KeyExpansion(Byte Masterkey[16], Byte Roundkey[11][16])
// The assignment of the execution of eight-shuffling AES
(*ptr_shuffle[8])(Byte PT[16], Byte RK[11][16], Byte CT[16])
ptr_shuffle[0] = &amp;AES_Original1
ptr_shuffle[1] = &amp;AES_Original1_Macro
ptr_shuffle[2] = &amp;AES_Original2
ptr_shuffle[3] = &amp;AES_Original2_Macro
ptr_shuffle[4] = &amp;AES_Bertoni
ptr_shuffle[5] = &amp;AES_Bertoni_Macro
ptr_shuffle[6] = &amp;AES_T-Table
ptr_shuffle[7] = &amp;AES_T-Table_Macro
// The execution of eight-shuffling AES
ptr_shuffle[shuffle](PT, RK, CT))
End
