Integrated circuit data protection

Techniques for providing data protection in an integrated circuit are provided. An example method according to these techniques includes determining that an unauthorized update has been made to software or firmware associated with the integrated circuit, and corrupting an anti-replay counter (ARC) value, maintained in a one-time programmable memory of the integrated circuit and used by the integrated circuit to protect contents of a non-volatile memory, responsive to determining that the unauthorized update has been made to the software or the firmware. 提供了用于在集成电路中提供数据保护的技术。根据这些技术的一种示例方法包括：确定已经对与集成电路相关联的软件或固件进行了未经授权的更新；以及响应于确定已经对软件或固件进行了未经授权的更新，来破坏防重放计数器(ARC)值，所述ARC值是在集成电路的一次性可编程存储器中维护的并且由集成电路用于保护非易失性存储器的内容。
