Ciphertext generated using a computationally secure encryption
scheme is impossible for an opponent to decrypt simply because
the required information is not there.

Question

Quizplus · Accepted Answer

In a computationally secure encryption scheme, the ciphertext is considered secure not because the information is missing, but because it would require an impractical amount of computational resources (time and/or processing power) for an opponent to decrypt it without the key.
