摘要

在安全协议的实现中使用的数据格式与安全协议的正式验证中使用的数据类型之间存在不匹配。我们为安全协议中使用的数据提出了一种经过验证的编码方案，它将形式世界的抽象数据类型连接到实现中可用的字节格式。编码灵感来自ASN1编码方案。编码是用Java实现的，并且根据正式规范证明该实现是正确的。该实现可以用作安全协议实现中的可重用参考库。这样做的好处是关注点分离:协议可以在抽象级别上进行验证。通过链接库自动更正到字节的映射。此外，编码本身就是一个具有挑战性的Java验证案例研究。

ASN1-light: A Verified Message Encoding for Security Protocols

There is a mismatch between the data format used in implementations of security protocols and the data types used in formal verification of security protocols. We present a verified encoding scheme for data used in security protocols, which links the abstract data types of the formal world to a byte format usable in implementations. The encoding is inspired by the ASN1 encoding scheme. The encoding is implemented in Java and the implementation is proven to be correct against a formal specification. The implementation can be used as a reusable reference library in security protocol implementations. The benefit is a separation of concerns: The protocol can be verified on an abstract level. The mapping to bytes is automatically correct by linking the library. Additionally the encoding is a challenging Java verification case study in its own.
