Use of indistinguishable response time
Summary​
Response time of authentication probes should be indistinguishable whether an user exists or not.
Description​
This requirement aims to ensure that, regardless of the input or conditions, the response time of a system remains indistinguishable. By carefully measuring response times, an attacker may infer details about the internal operations of a system, and maybe exposing sensitive information.
