简介（Introduction）¶

E2EL在架构上属于AUTOSAR静态库代码，使用同样属于静态库代码的CRC模块来进行安全数据的保护，E2E XF通过把E2EL的相关算法抽象成用户易操作的配置项和配置界面，并根据用户的属于生成代码，来帮助用户更好的使用E2EL来保护数据。

Architecturally, the E2E Library (E2EL) is implemented as an AUTOSAR static library. It utilizes the CRC module—also a static library component—to protect safety-critical data. The E2E Transformer (E2E XF) abstracts E2EL’s complex algorithms into user-configurable parameters and interfaces. Based on user inputs, it auto-generates code to simplify the adoption of E2EL for robust data protection.

功能描述（Functional Description）¶

特性（Features）¶

E2EL的各个profile提供了一种可以满足功能安全目标的数据保护机制，各个E2E profile通过不同的算法和API完成以下类型的数据保护机制：

Each profile of E2EL provides a data protection mechanism that can meet functional safety goals. Each E2E profile accomplishes the following types of data protection mechanisms through different algorithms and APIs:

集成CRC库的CRC保护机制；

A CRC, provided by CRC Supervision;
接收端检测接收报文的递增计数器，判断接收数据是否有序递增；

A Sequence Counter incremented at every transmission request, the value is checked at receiver side for correct incrementation;
接收端通过检测心跳计数器判断数据是否发生改变；

An Alive Counter incremented at every transmission request, the value checked at the receiver side if it changes at all;
通过特定的ID来区分不同的I-PDU组；

A specific ID for different I-PDU groups;
超时检测机制（接收报文超时和发送确认超时）；

Timeout detection (Receiver communication timeout and Sender acknowledgement timeout);
E2E profiles的用户需要根据自己的应用场景决定选用哪种类型的E2E profile；

Users of E2E profiles need to decide which type of E2E profile to use according to their own application scenarios;
E2E支持的profile有profile1、profile2、profile4、profile4m、profile5、profile6、profile7、profile7m、profile8、profile8m、profile11、profile22、profile44、profile44m。

The profiles supported by E2E include profile1, profile2, profile4, profile4m, profile5, profile6, profile7, profile7m, profile8, profile8m, profile11, profile22, profile44, and profile44m.
