ROP Defense Using Trie Graph for System Security

Research on Network Defense Graph Model in Network Security

Security analysis and attack-defense modeling are effective method to identify the vulnerabilities of information systems for proactive defense. The attack graph model reflects only attack actions and system state changes, without considering the perspective of the defenders. To assess the network information system and comprehensively show attack and defense strategies and theirs cost, a defen...

An Efficient Trie Hashing Method Using a Compact Binary Trie

In many applications, information retrieval is a very important research eld. In several key strategies, the binary trie is famous as a fast access method to be able to retrieve keys in order. However, if the binary trie structure is implemented, the greater the number of the registered keys, the larger storage is required, as a result, the binary trie can not be stored into the main memory. In...

A Security Effective Structure for National Defense in the 21st Century

In accordance with human necessities and deep attention into security, research studies have today became an irrefutable necessity in this area. It is noted that traditional concepts of this important issue have changed, as a result of occurring various events in the past, particularly in the 20th century; so that security is no more limited to protecting human beings against individual and col...

Image Security by Using Fuzzy Graph

In the current time, especially in the computer world, the security of data becomes an important issue. This paper presents a novel fast method for encrypting and decrypting images, based on fuzzy graph (FG) mapping technique. The Fuzzy graphs are obtained from a matrix of image’s pixels, and then they are used to encrypt an image. The experimental results show that this method is more efficien...
