The Entropy Pool ability grants a +1 enhancement bonus to AC.
The Entropy Strike is treated as a weapon with the operative and blocking properties.
The blocking property has the effect that when you successfully strike a target with a melee attack using such a weapon, you gain a +1 enhancement bonus to your AC for 1 round against melee attacks from that target.
If the defensive bonuses from entropic pool and entropic strike are intended to work together, one of them may need to change type.
