Light and Secure Encryption Technique Based on Artificially Induced Chaos and Nature-Inspired Triggering Method

Abstract

Encryption is the de facto method for protecting information, whether this information is locally stored or on transit. Although we have many encryption techniques, they have problems inherited from the computational models that they use. For instance, the standard encryption technique suffers from the substitution box syndrome—the substitution box does not provide enough confusion. This paper proffers a novel encryption method that is both highly secure and lightweight. The proposed technique performs an initial preprocessing on its input plaintext, using fuzzy substitutions and noising techniques to eliminate relationships to the input plaintext. The initially encrypted plaintext is next concealed in enormously complicated codes that are generated using a chaotic system, whose behavior is controlled by a set of operations and a nature-inspired triggering technique. The effectiveness of the security of the proposed technique is analyzed using rigorous randomness tests and entropy.

An Efficient Authentication Protocol Based on Chebyshev Chaotic Map for Intelligent Transportation

“… The RSU gets the true value of the vehicle verification key 𝑉 𝑖 according to (23). Therefore, it validates the correctness of the received signatures 𝑆 𝑣 and 𝐶 𝑖 by (24). Any attacker's attempt to alter the values of 𝐾 1 , AID i , 𝐸 𝑖 , and 𝑡 2 leads to a mismatch in (24).…”

If the term of T 𝑔 SP 2 (𝐶 𝑖 ) mod 𝑃 is equal to the term of T 𝑔 SP 3 − 𝜓 (𝑆 𝑣 ) mod 𝑃, the RSU decrypts 𝐸 𝑖 to obtain the private service request PRq that is required by the vehicle according to (25).…”

“…Throughout this section, two main verification methods are introduced to confirm the security robustness of the proposed protocol as follows: The first method is informal verification, which involves analyzing the core characteristics of the protocol procedures, whereas the second method includes formal verification tool, which is utilized to test the resistance of the new protocol to various attacks.  The Chebyshev chaotic map: It is increasingly applied in various recent research papers due to its lightweight computations [15]- [18], [23], [24].  The logical shift function and arithmetic (addition/subtraction) operations: According to [24], it is found that these tools require a negligible execution time.…”

“…4, the proposed protocol utilize few number of tools. According to [15]- [18], [24], these tools are considered as lightweight functions.  As previously illustrated in the section VI, the performance of the new protocol has evaluated according to the Wolfram Mathematica program, proving that the proposed protocol has lower computational, communication, and storage costs than the most closely related scheme [15].…”
