| dc.description.abstract | With the development of computer technology, is now a multi-user application on the performance of a computer, the data can be shared with other users on the computer or in a wider network.
But in addition to the data that can be distributed there that requires privacy and must be kept confidential. This important data must be protected from those who are not responsible either against counterfeiting, theft, and illegal data conversion. To overcome these problems, one of the solutions that can be taken is to cryptography. This way the data will be encoded by a particular method so that people who are not interested and do not have the right to access will be difficult to do things that are not desirable. Many cryptography that has been created by researchers who aim to secure cryptographic data or information. LUC algorithm is a cryptographic method using two different keys in cryptography. Text file used to encrypt the encryption function that uses a public key, encrypted files encrypted form safe from noise. Rabin algorithm is an encryption method that is similar Asymmetric ciphers such as RSA, factoring the numbers. Rabin algorithm is a variant of the RSA algorithm. The basic function of Rabin algorithm similar to the basic functions of the RSA algorithm. It's just computing Rabin algorithm is simpler than the RSA algorithm | en_US |
