Opaque IDs: the ultimate protection against enumeration attacks
·11 mins
IDs in APIs and applications might be exploited to gain unauthorised access to other data or otherwise disclose information by means of various attacks, such as timing attacks and enumeration attacks. For instance, an attacker can use sequential IDs to guess the existence of IDs and perform enumeration attacks. Authenticated Encryption with Associated Data (AEAD) encryption and opaque IDs can be used as a means of neutralising these attacks.
