Abstract

PDAM (Perusahaan Daerah Air Minum) is a local government-owned company engaged in the distribution of clean water to the general public within the Indonesian local government. PDAM develops its technology and information systems specifically in the field of Internet of Things. The process handled is the prepaid PDAM transaction process which is carried out online. This prepaid PDAM transaction module really needs data security that can maintain the data transmission process on IoT devices. In this study, the design of a data security system using the PGP (Pretty Good Privacy) method is modified using the Eliptic Curve and BlowFish algorithms. The modified PGP method uses the SHA1 algorithm as a digital signature, Eliptic Curve cryptography is used as the Public Key encryption and Blow Fish cryptography is used as the symmetric encryption key. Attempted attacks with the man in middle attack cannot occur because the public key encryption uses the Eliptic Curve algorithm so it takes a very long hacking time
