Non-malleable code

Non-malleable code is a concept in the field of cryptography and information security that pertains to the resilience of a code or program against tampering. In essence, it provides a guarantee that even if an adversary modifies the encoded data in some way, the result will either remain invalid or will not lead to a meaningful or predictable outcome. The main idea behind non-malleable coding is to protect data from modifications that could alter its intended behavior or value in a controlled way.
