- Abstract
With the introduction of the concept of information warfare, the way military operations are done is changing quickly. Now, much more than it was in past, quick acquisition of information and effective decision making are crucial. Especially, these days the ratio of multimedia data is on the rise. A data management system has been put in place since the 1980s which encrypts information before storing it, and allowing only authorized users to gain access to it according to the proper procedures. In this paper, a secure and effective multimedia data management system that uses homomorphic operations is designed and implemented. By using homomorphic operations, it is able to quickly process stored ciphertext without a decryption process, allowing fast decision making after information gathering in a NCW environment. In order to assess the performance of the effective multimedia data management system implemented in this paper, it was compared to an ordinary system in which ciphertext has to be first decrypted before it can be modified. The secure and effective multimedia data management system for information warfare implemented in this study is highly versatile because any public encryption algorithm can be used, and has short response times thanks to the homomorphic algorithm which allows processing to be done directly on the ciphertext.
