Abstract

This study presents a logic-locking scheme based on the binary ring learning with error (bin-RLWE) algorithm, implemented in a reduced instruction set computer-five (RISC-V) system-on-chip (SoC) design. Unlike traditional logic-locking methods that require providing users with raw locking parameters, the proposed approach secures critical logic paths in the privilege switching process without exposing these sensitive parameters. The implemented locking module itself consumes 3519 lookup tables (LUTs) and 2645 registers, leading to an overall overhead of 6.0% in LUTs and 6.9% in registers compared to the baseline system. The unlock process requires about

$2.6~\mu $

s, introducing moderate performance impact and primarily affecting system-level operations while preserving user-level computational efficiency.

在片上系统设计中实现同态加密逻辑锁定

本研究提出了一种基于误差二进位环学习（bin-RLWE）算法的逻辑锁定方案，并在精简指令集计算机五（RISC-V）片上系统（SoC）设计中实现。传统的逻辑锁定方法需要向用户提供原始锁定参数，而本文提出的方法在不暴露这些敏感参数的情况下保护特权切换过程中的关键逻辑路径。实现的锁定模块本身消耗3519个查找表（lut）和2645个寄存器，与基线系统相比，导致lut和寄存器的总开销分别为6.0%和6.9%。解锁过程大约需要$2.6~\mu $ s，带来适度的性能影响，主要影响系统级操作，同时保持用户级计算效率。

期刊介绍： The IEEE Transactions on VLSI Systems is published as a monthly journal under the co-sponsorship of the IEEE Circuits and Systems Society, the IEEE Computer Society, and the IEEE Solid-State Circuits Society. Design and realization of microelectronic systems using VLSI/ULSI technologies require close collaboration among scientists and engineers in the fields of systems architecture, logic and circuit design, chips and wafer fabrication, packaging, testing and systems applications. Generation of specifications, design and verification must be performed at all abstraction levels, including the system, register-transfer, logic, circuit, transistor and process levels. To address this critical area through a common forum, the IEEE Transactions on VLSI Systems have been founded. The editorial board, consisting of international experts, invites original papers which emphasize and merit the novel systems integration aspects of microelectronic systems including interactions among systems design and partitioning, logic and memory design, digital and analog circuit design, layout synthesis, CAD tools, chips and wafer fabrication, testing and packaging, and systems level qualification. Thus, the coverage of these Transactions will focus on VLSI/ULSI microelectronic systems integration.
