Abstract
The objective of this research was to design a security protocol of database manipulation. Stakeholder of this protocol were Security Administrator (SA), Database Client (DC), and Database Administrator (DA). SA was responsible in data encryption and decryption. DA acted just as a data keeper. DC was one who process data manipulation on plain data. Under SA responsibility, cipher text was transformed to secret shares. After that, this secret shares were sent to be kept in many database engines under DA’s management. When DC requested specific record for data processing task, The ID of this record was sent to SA. SA requested this defined record ID to all DA. All DA retrieved ordered record ID from their database engine then sent it back to SA. SA used these secret shares to reconstruct the plain text then sent it to DC in order to perform any processing on plain data. When the processing was ended, SA compiled encrypt the new plain text and do transform this one to a new secret shares and repeat sending them to DA to look after the secret shares again as before. These designed security protocol, especially in data processing, were written as function program prototype. The function program prototype and detail of designed security protocol were sent to five security experts in order to evaluate of its performance and data processing correction. Evaluation result indicates that average appreciation on all evaluation topics were in good level (3.60). Expert’s opinion on possibility of practicable application was about 70.20%.
