Optimized Design and Implementation of CRYSTALS‐KYBER Based on MLWE

Security and Communication Networks, Volume 2025, Issue 1, 2025.
CRYSTALS‐KYBER is a postquantum key exchange mechanism based on the MLWE problem. At present, it is a major challenge to realize CRYSTALS‐KYBER with high‐performance and low‐resource consumption on the FPGA platform. The design proposed in this paper aims at the high efficiency implementation of CRYSTALS‐KYBER based on the MLWE scheme.

High-Speed Key Encapsulation from NTRU

, 2017
This paper presents software demonstrating that the 20-year-old NTRU cryptosystem is competitive with more recent lattice-based cryptosystems in terms of speed, key size, and ciphertext size. We present a slightly simplified version of textbook NTRU, select parameters for this encryption scheme that target the 128-bit post-quantum security level ...

Bilevel access control and constraint‐aware response provisioning in edge‐enabled software defined network‐internet of things network using the safeguard authentication dynamic access control model

International Journal of Communication Systems, Volume 37, Issue 18, December 2024.
A centralized controller vulnerable to attacks is one of the security vulnerabilities and scalability issues faced by the Internet of Things (IoT)‐connected software‐defined network (SDN). Safeguard Authentication Dynamic Access Control (SANDMAC) tackles these issues by emphasizing secure access control and user and application authentication ...

A new efficient asymmetric cryptosystem based on the integer factorization problem of N=p2q [PDF]

, 2013
In this paper, we introduce a new scheme based on the hardness of factoring integers of the shape N = p2q. Our scheme uses a combination of modular linear and modular squaring. We show that the decryption is 1-to-1 which is a great advantage over Rabin's

Secure data sharing technology of medical privacy data in the Web 3.0

IET Blockchain, Volume 4, Issue 4, Page 335-343, December 2024.
The article proposes and implements a secure sharing model for medical privacy data based on key Web3 technologies. It constructs keyword indexes for private data, stores the source data in the Inter Planetary File System, and uses query keywords to generate trapdoors, thereby enabling the retrieval of encrypted data.
