The major web browsers rely on the “CA Trust Model” to authenticate the identity of the owners/operators of websites to end-users. Browsers perform this authentication using digital certificates issued by third-party “certificate authorities” or “CAs.” The CAs, for their part, issue digital certificates to browsers as well as to websites. Browsers then use these CA-issued certificates to verify a website’s identity when a website offers a secure connection to an end-user. As a practical matter, the CA Trust Model plays a hugely important role in enabling commercial transactions and a wide assortment of other private communications over the Internet. The purpose of the Model is to allow end-users to have a high level of confidence in the identity of the party with whom they are communicating. Given the importance of the CA Trust Model to commerce and security, one would expect the legal relationships between CAs, websites, and end-users to be well-defined. But is that, in fact, the case? This presentation will seek to answer that question by briefly (and painlessly) analyzing key provisions in the standard CA-issued legal documents to determine whether those provisions are likely to be enforceable and, if so, assessing their potential impact on end-users, website operators, and the CAs. The presentation will also explore the legal relationship between the parties to the CA Trust Model in the absence of enforceable documents issued by the CA.
