| 摘 要： | 随着计算机和通信技术的发展，ASN．1作为多种协议在表示层的抽象语法记法，它的作用在多媒体通信，协议测试等领域都非常重要。该文采用面向对象的设计方法实现了ASN．1标准X690，同时，通过比较各种编码规则的特点，在BER编解码实现的基础上，给出CER、DER及PER编码的实现方案，据此实现的ASN．1编解码对外提供了一致的接口，具有很好的通用性。

| Abstract: | With the development of computer and communication technology, being an abstract syntax notation of implementations of various protocols in representation layer, ASN.1 becomes very importment in many areas such as multi-media communication and protocol testing.The paper realizes the standard X.690 of ASN.1 with object-oriented method.By comparing differences among all encoding rules, and gives implementation projects of other rules such as CER,DER and PER based on BER.The encoding and decoding for ASN.1 provide an identical interface , which makes it more universal. |
