AI Technical Summary

Technical Problem

Existing multi-port memory systems cannot provide persistent protection and resilience against complex network attacks, are vulnerable to denial-of-service attacks, and have limited security based on software locking features, making them susceptible to management port tampering and power cycling.

Method used

Employing authentication and hardware-based locking features, the lock configuration is stored in both the authentication key protection section and the hardware pin protection section, ensuring that the operation remains valid after a power cycle. The persistence and security of the lock configuration are achieved by combining the authentication key and the physical connection of the hardware pin.

Benefits of technology

It improves the security of the memory system, reduces denial-of-service attacks and system failures, lowers the power and computational resource consumption of error correction, and provides a more robust anti-tampering security layer.

Abstract

The invention relates to an authentication-based and hardware-based locking feature for a memory system. In some embodiments, a memory system may receive a lock command associated with one or more operations of the memory system, where the lock command indicates, for each operation, whether the operation is to be locked using an authentication-based lock feature, and whether the operation is to be locked using a hardware-based lock feature. The memory system may perform at least one of: when the lock command indicates that a first operation is to be locked using the authentication-based lock feature, storing a first lock configuration associated with the first operation in an authentication key protection portion of the memory system; or when the lock command indicates that a second operation is to be locked using the hardware-based lock feature, storing a second lock configuration associated with the second operation in a hardware pin protection portion of the memory system.
