This paper focuses on building cryptographic systems using a scrambler circuit constructed using reversible logic gates, S-Box, a barrel shifter, and an LFSR that generates a 4-bit random key which is then used as a dual key for XOR and a barrel shifter.
In an era marked by escalating security concerns and an ever-growing need for robust data protection, the development of efficient and secure cryptographic systems has become imperative. This paper introduces novel VLSI architectures designed for security analysis, incorporating a Dual-Key Linear Feedback Shift Register (LFSR) coupled with advanced components such as a Barrel Shifter and an S-Box.
The proposed architecture addresses the challenges of secure data transmission and encryption by leveraging a Dual-Key LFSR configuration. This innovative approach enhances the cryptographic strength by introducing two independently controlled LFSRs, effectively doubling the key space and making it considerably more resistant to brute force attacks.
