Hardware Security Features

BGA Package

保护设备免受探测,因为球是在设备的底部,并焊接到PCB板.

Hardware Write Protect

防止意外或恶意编程或擦除通过硬件引脚启用:

  • 只有当存在有效电压时才能修改块
  • 只有在设备接地时才被编程或擦除的块

LOCK Pin (NAND Only)

Protects the entire device or certain ranges of blocks from being programmed and erased; LOCK pin can be enabled/disabled at power-on.

  • 如果上电时LOCK为LOW,则所有BLOCK LOCK命令都将被禁用.
  • 如果上电时LOCK为HIGH,则表示启用BLOCK LOCK命令.
  • Features:
    • Unlock: 为程序和擦除解锁特定范围的块.
    • Lock:  锁定整个设备的程序和擦除.
    • Lock tight:  Freezes the block lock/unlock scheme.
    • Protect:  Permanently protects blocks 0H to 47H.

Software Security Features

Volatile Block Locking

通过将具有临时写保护的区域处理为只读,防止由于编写不良的软件或在设备上电期间对闪存阵列进行意外程序或擦除,而不会磨损阵列.

Nonvolatile Block Locking

防止意外或恶意编程或擦除, with functionality dependent on the memory family; the PROTECT command can be used to permanently protect blocks from programming and erasing.

唯一ID -一个32位或64位的序列号,编程到美光的NAND和NOR闪存设备,不能更换或修改

提供存储在内存设备中的固定值, 启用组件身份验证技术以减少组件交换,并在处理器和内存之间创建关系以防止克隆.

Password Protect Block Locking

通过要求64位或128位的密码,保护块不被修改——即使在断电或设备重置时也是如此.

ATA Password (SSDs Only)

Prevents access to an SSD during power-up by requiring a password; the ATA password is hidden in an area of the drive (not software) that is inaccessible to users.

AES256 Encryption (SSDs Only)

使用对称加密算法加密飞行中的数据和静止的数据,这是美国的标准.S. and Canada; if correctly implemented, 如果没有非凡的处理能力,AES256是不可能在一个生命周期内被破解的.

Sanitize and Secure Removal

通过物理擦除数据并在其上重新编程“虚拟”数据来保护已删除的数据和以前版本的数据,以确保数据不可恢复.

Advanced Security Features

One-Time Programming (OTP)

Permanently locks flash blocks so they can no longer be erased or written to; OTP is commonly used to protect initialization or boot code in a system, helping to prevent corruption.

OTP Space

允许将少量信息或代码嵌入到内存中不能擦除或写入的附加空间中.

Replay-Protected Memory Block (RPMB) (e.MMC Only)

启用用于存储少量敏感信息的安全内存块, 保持唯一性,帮助系统更好地抵抗回滚和重放攻击; RPMB enables a secure relationship between the host controller and the memory device.

重放保护单调计数器(RPMC)(仅限串行NOR)

向引导内存中的代码和数据存储添加安全的增量单调计数, 保持唯一性,帮助系统更好地抵抗回滚和重放攻击.
