computational security造句

The first such flavour is whether the commitment scheme provides perfect or computational security with respect to the hiding or binding properties.
For schemes based on computational security, the adversary is modeled by a probabilistic polynomial time Turing machine, meaning that it must complete the game and output a " guess " within a polynomial number of time steps.
In light of this, and the practical difficulty of managing such long keys, modern cryptographic practice has discarded the notion of perfect secrecy as a requirement for encryption, and instead focuses on " computational security ", under which the computational requirements of breaking an encrypted text must be infeasible for an attacker.
The first are those designed with the intent to protect against hackers and attackers who have infinite resources with which to decode a message ( theoretical secrecy, now unconditional security ), and the second are those designed to protect against hackers and attacks with finite resources with which to decode a message ( practical secrecy, now computational security ).
It's difficult to find computational security in a sentence. 用computational security造句挺难的
