Key-space analysis of double random phase encryption technique.
We perform a numerical analysis on the double random phase encryption/decryption technique. The key-space of an encryption technique is the set of possible keys that can be used to encode data using that technique. In the case of a strong encryption scheme, many keys must be tried in any brute-force attack on that technique. Traditionally, designers of optical image encryption systems demonstra...
متن کاملEfficient Text Encryption and Hiding with Double-Random Phase-Encoding
In this paper, a double-random phase-encoding technique-based text encryption and hiding method is proposed. First, the secret text is transformed into a 2-dimensional array and the higher bits of the elements in the transformed array are used to store the bit stream of the secret text, while the lower bits are filled with specific values. Then, the transformed array is encoded with double-rand...
متن کاملRandom Key Pre-Distribution Techniques against Sybil Attacks
Sybil attacks pose a serious threat for Wireless Sensor Networks (WSN) security. They can create problems in routing, voting schemes, decision making, distributed storage and sensor re-programming. In a Sybil attack, the attacker masquerades as multiple sensor identities that are actually controlled by one or a few existing attacker nodes. Sybil identities are fabricated out of stolen keys, obt...
متن کاملDefend encryption systems against side- channel attacks
From its ancient origin as a tool for protecting sensitive wartime or espionage-related messages, cryptography has become a foundational building-block for securing the systems, protocols, and infrastructure that underpin our modern interconnected world. But the physical mechanisms used in performing encryption and decryption can leak information, making it possible to bypass this security. Pro...
متن کاملOn Selective-Opening Attacks against Encryption Schemes
At FOCS’99, Dwork et al. put forth the notion of ‘selective-opening attacks’ (SOAs, for short). In the literature, security against such attacks has been formalized via indistinguishability-based and simulation-based notions, respectively called IND-SO-CPA security and SIM-SO-CPA security. Furthermore, the IND-SO-CPA notion has been studied under two flavors – weak-IND-SO-CPA and full-IND-SO-CP...
