Encryption

The coding of sensitive information for transfer online or otherwise electronically. One may encrypt data to prevent anyone other than the intended recipient from accessing it. For example, if one buys a product online and enters credit card information into an electronic form, that information is usually encrypted so hackers and potential identity thieves cannot use it for illicit purposes.

encryption

The manipulation of data to prevent accurate interpretation by all but those for whom the data is intended. Financial institutions use encryption to increase the security of data transmitted via the Internet.

In order to ensure the security of the scheme, the parameters in the above method need to meet the following restrictions: to resist violent attacks, select [rho] = [omega] (log[lambda]); in order to make the compressed decryption circuit belong to the permissible circuit, select [??]; to resist the lattice-based attack, choose [gamma] = [omega] ([[eta].sup.2] log[lambda]); apply the residual hash theorem to the approximation of the approximate GCD problem, choose [alpha] [tau] [greater than or equal to] [gamma] + [omega] (log[lambda]); To ensure correct decryption of ciphertext, select [eta] [greater than or equal to] [rho] + [alpha] +2 + [log.sub.2] [tau] ; second noise parameter [rho]' = [rho] + [alpha] + [omega] (log[lambda]).
