Abstract
A server receives a request from the client. The request includes a cryptographically protected object that includes a respective user identifier and validation value. When the respective user identifier is valid, the validation value fails a first requirement in a predefined manner, and a count of consecutively received cryptographically protected objects whose validation value has failed the first validation requirement is less than a threshold value that is greater than one, the server returns to the client a response to the request in accordance with the respective user identifier, the response including an updated cryptographically protected object that includes the respective user identifier and an updated validation value, and updates the count. When the respective user identifier is valid, the validation value fails a first requirement in the predefined manner, and the count is equal to or exceeds the threshold value, the server performs a predefined remedial action.
