Symmetric cryptography uses a unique key for both encryption and decryption. There is an issue that rose regarding the key transaction which might be interrupted by an unauthorized party and it costs a high price. Thus, key pre-distribution scheme is created in order to overcome the mentioned issue. One of the protocols is Blom's Key Pre-distribution scheme. However, Blom' s Key Pre-distribution scheme uses integer finite field which makes this scheme to be easy to be intervened by attackers. Hence, this project suggests a different appeal by implementing elliptic curve into the Blom's Key Pre-distribution scheme to overcome the disadvantages since the security of elliptic curve is better than the prime number being used in the original scheme. As a result, the overall process of the modification of Blom's Key Pre-distribution scheme techniques is presented and demonstrated through a Graphical User Interface (GUI). The future researches of this same study should consider applying some of the protocols in Elliptic Curve Cryptography (ECC) and run a few tests on the scheme to ensure the perfonnance of the modified scheme.
