👉 In computer science, "pre-secure" refers to a cryptographic technique that allows an attacker to obtain some information about a given secret key without revealing it directly. This is typically done by using a pre-verified version of the secret key or a pre-validated message. For example, if you have a secret key (e.g., AES) and want to encrypt data with it, you first need to generate a pre-verified copy of the key, which includes all possible modifications that could be
