The disclosed embodiments provide for detection of fraudulent electronic security tokens. The cracked private key allows forgery of the electronic security token, which then allows access to the computer resource. Some embodiments track serial numbers issued by a token issuer, and then can predict serial numbers issued forward by the token issuer. Some embodiments also determine the validity of the token based at least in part on a service or client attempting to access the resource using the token. For example, some disclosed embodiments maintain reputation data for a client or service utilizing an electronic token, and determine whether the token is likely to be valid based on the client or service reputation. 所公开的实施例提供了对欺诈性电子安全令牌的检测。被破解的私钥允许伪造电子安全令牌，这然后允许访问计算机资源。一些实施例跟踪由令牌发行机构所发行的序列号，然后能够预测由令牌发行机构向前发行的序列号。一些实施例还至少部分地基于尝试使用令牌访问资源的服务或客户端来确定令牌的有效性。例如，一些公开的实施例维护利用电子令牌的客户端或服务的信誉数据，并基于客户端或服务信誉来确定令牌是否可能有效。
