F8652E HIMA 连接中央模块

【产品详情】

对于串行接口只有公交车站号。1 ~ 31可设置。

在乙太网路中，公车站编号。取值范围为1 ~ 99。因此，除了S1-1/2/3/4/5之外，还必须设置S1-6/7开关。

网络中通信伙伴的数量仍然限制在64个。

这个加强了的公共汽车站的设置。只能从操作系统BS41q/51q V7.0-8(05.31)的中央模块。

使用通信模块f8627x的应用:

-连接中央模块到一个PADT (ELOP II TCP)

-连接到以太网内的其他通信伙伴(安全以太网，Modbus TCP)

通信从中央模块通过背板总线运行到通信模块F 8627X，从F 8627X的以太网端口运行到以太网，反之亦然。

中央模块特点:

-自学:来自操作系统BS41q/51q V7.0-8 (05.31)

– ELOP II TCP:来自操作系统BS41q/51q V7.0-8 (05.31)

巴士站详情:， ELOP II TCP，操作系统和应用程序的加载(自学)等。这些核心模块对应于F8627X的数据表以及H41q/H51q的操作系统手册和H41q/H51q的安全手册。

硬件安全模块（hardware security module，缩写HSM）是一种用于保护和管理强认证系统所使用的密钥，并同时提供相关密码学操作的计算机硬件设备。硬件安全模块一般通过扩展卡或外部设备的形式直接连接到电脑或网络服务器。HSM提供篡改留证（tamper evidence/proof）、篡改抵抗（tamper evidence）两种方式的防篡改功能，前者设计使得篡改行为会留下痕迹，后者设计使得篡改行为会令HSM销毁密钥一类的受保护信息。

每种HSM都会包括一个或多个安全协处理器，用于阻止篡改或总线探测。许多HSM系统提供可靠的密钥备份机制，使机密数据可以通过智能卡或其他设备安全地处理或转移。由于HSM通常是公钥基础设施（PKI）或网上银行一类关键基础设施的一部分，一般会同时使用多个HSM以实现高可用性。

一些HSM具备双电源、无需停机更换配件（如冷却风扇）等设计，以确保在数据中心等环境中的高可用性要求。少数HSM可以让用户在其内部处理器上运行专门开发的模块。在一些场景下，这种设计相当实用，例如用户可以在这种安全、受控的环境下运行一些特殊的算法或者业务逻辑，哪怕攻击者取得了计算机的完全控制权限，存储在HSM（连接到计算机）中的程序也无法被提取或篡改。

一般HSM允许用户使用C、.NET、Java等编程语言开发这种专用程序。值得注意的是，用户自定义的程序与HSM本身的程序之间存在隔离，这使程序的存在不会影响到HSM本身的安全。考虑到硬件安全模块（HSM）在应用程序与基础设施的安全中扮演的关键角色，此类密码学模块通常都会经过Common Criteria、FIPS 140等受到国际承认的认证。

【英文介绍】

For serial interface only bus stop number. The value ranges from 1 to 31.

In Ethernet, bus stop numbers. The value ranges from 1 to 99. Therefore, in addition to S1-1/2/3/4/5, the S1-6/7 switch must also be set.

The number of communication partners in the network is still limited to 64.

This enhanced bus stop setup. Only from the central module of operating system BS41q/51q V7.0-8(05.31).

Applications using the communication module f8627x:

- Connect the central module to a PADT (ELOP II TCP)

- Connect to other communication partners within Ethernet (Secure Ethernet, Modbus TCP)

Communication runs from the central module through the backplane bus to the communication module F8627X, from the Ethernet port of the F8627X to the Ethernet, and vice versa.

Central module features:

- Self-study: from operating system BS41q/51q V7.0-8 (05.31)

- ELOP II TCP: from operating system BS41q/51q V7.0-8 (05.31)

Bus stop details: ELOP II TCP, operating system and application loading (self-study), etc. These core modules correspond to the F8627X data sheet as well as the H41q/H51q operating system manual and the H41q/H51q Safety manual.

A hardware security module (HSM) is a computer hardware device that protects and manages the keys used by a strong authentication system while providing related cryptographic operations. Hardware security modules are usually connected directly to a computer or network server in the form of expansion cards or external devices. HSM provides tamper evidence/proof (tamper evidence) and tamper evidence resistance (tamper evidence). The former is designed so that tampering will leave traces, and the latter is designed so that tampering will make HSM destroy protected information such as keys.

Each HSM includes one or more security coprocessors to prevent tampering or bus detection. Many HSM systems provide a reliable key backup mechanism that allows confidential data to be securely processed or transferred via smart cards or other devices. Because HSMS are often part of a critical infrastructure such as public key infrastructure (PKI) or online banking, multiple HSMS are often used simultaneously to achieve high availability.

Some HSMS are designed with dual power supplies and no downtime to replace accessories, such as cooling fans, to ensure high availability requirements in environments such as data centers. A few HSMS allow users to run specially developed modules on their internal processors. In some cases, this design is quite useful, such as the user can run some special algorithms or business logic in this secure, controlled environment, even if the attacker gains full control of the computer, the program stored in the HSM (connected to the computer) cannot be extracted or tampered with.

General HSM allows users to use C,.NET, Java and other programming languages to develop such specialized programs. It is worth noting that there is a separation between user-defined programs and the HSM's own programs, so that the existence of the program does not affect the security of the HSM itself. Given the critical role that hardware security modules (HSM) play in the security of applications and infrastructure, such cryptography modules are typically certified by internationally recognized standards such as Common Criteria and FIPS 140.
