Security of data stored on computers is now an absolute requirement, because every data has a high enough value for the user, reader and owner of the data itself. To prevent misuse of the data by other parties, data security is needed. Data security is the protection of data in a system against unauthorized authorization, modification, or destruction. The science that explains the ways of securing data is known as cryptography, while the steps in cryptography are called critical algorithms. At this time, there are many cryptographic algorithms whose keys are weak especially the symmetric key algorithm because they only have one key, the key for encryption is the same as the decryption key so it needs to be modified so that the cryptanalysts are confused in accessing important data. The cryptographic method of Word Auto Key Encryption (WAKE) is one method that has been used to secure data where in this case the writer wants to maximize the encryption key and description of the WAKE algorithm that has been processed through key formation. One way is to apply the algebraic pascal triangle method to maximize the encryption key and description of the WAKE algorithm, utilizing the numbers contained in the columns and rows of the pascal triangle to make shifts on the encryption key and the description of the WAKE algorithm.Keywords: Cryptography, WAKE, pascal

With the enormous growth in the Internet and network, data security has become an inevitable concern for any organization. From antecedent security has attracted considerable attention from network researchers. In this perspective many possible fields of endeavour come to mind with many cryptographic algorithms in a broader way, each is highly worthy and lengthy. As society is moving towards digital information age we necessitate highly standard algorithms which compute faster when data size is of wide range or scope. On survey, numerous sequential approaches carried out by symmetric key algorithms on 128 bits as block size are ascertained to be highly in securable and resulting at a low speed. As in the course the commodities are immensely parallelized on multi core processors to solve computational problems, in accordance with, propound parallel symmetric key based algorithms to encrypt/decrypt large data for secure conveyance. The algorithm is aimed to prevail by considering 64 character (512 bits) plain text data, processed 16 characters separately by applying parallelism and finally combine each 16 character cipher data to form 64 character cipher text. The round function employed in the algorithm is very complex, on which improves efficacy.

This study combines classic and modern cryptographic algorithms so that the data security of information more awake authenticity. Caesar cipher is the oldest classical cryptography which uses a symmetric key method is the key used for encryption is the same as the key used for the decryption process. Three-Pass Protocol is one of the modern cryptography where the process of sending a message does not need to distribute the key so that each party both the recipient and sender of the message does not need to know each lock. In this combination of receiving and sending messages using the Caesar Cipher algorithm for encryption and decryption, while for its delivery process using algorithms Three Pass protocol. The results from the combination of the two algorithms are to help the information sent is secure.

Data security is one of the most important factors in the world of Information Technology today. One way to secure data is by Block Cipher Cryptography technique. However, some cryptographic techniques have been successfully solved by the cryptanalysis so that new cryptographic algorithms need to be created. The design of Cryptography algorithms based on traditional game patterns of Rangku Alu from East Nusa Tenggara is a design of Cryptographic Block Cipher algorithms that operate in the form of bits designed with 10 rounds where each cycle contains four processes. In each round there are four patterns for the plaintext process and four patterns for the key. The fourth process is transformed with an S-Box table to get a more random ciphertext. Tests were also carried out using Avalance Effect which reached 49,38% and the correlation value where there was a change in character reached 73,44%. So the result designing Cryptographic algorithms can be used for encryption and description in text files.

Security is very important in all aspects to protect data. Text messages on mobile phones, which is sms (short messages service) is one of theimportant data that needs a data security system. Data security is used to maintain the confidentiality of important data that we have on mobile devices.The encryption process is used so that messages cannot be read by other unwanted parties. While the decryption process is used so that the messagecan be read back by the intended party. Rivest Cryptography, Shamir, Adleman (RSA) is one of the asymmetric cryptographic algorithms that use a keypair, that is the public key and private key. The key length can be set, where the longer the key formation bit, the harder it is to solve because it is difficultto factor two very large numbers. This study applies the Rivest, Shamir, Adleman (RSA) algorithm for text message security applications based onAndroid. Based on the research that has been done, the author can draw conclusions, namely: Rivest, Shamir, Adleman (RSA) cryptographic algorithmcan be implemented for text message security Android based. So it is safer to exchange text messages (SMS) so that user privacy is guaranteed

Ksecurity wheel is one of the essential needs of the data, or information. With this regard the importance of the information or data by the party or person of interest. This research aims to design and build a system for data security deed of sale that can help the Notary / PPAT. The system was built using the RC4 (Rivest Code 4) which is a symmetric key cryptographic algorithms and is stream cipher, there is a process of encryption and decryption. The encryption is the process of encoding the original message or plaintext into ciphertext encrypted text. While decryption is the process of encoding back to cipherteksmenjadiplainteks (original data). This research resulted in a system that is able to change the data that can be read into the data that is not easily understood.

<br /><em>Cryptography is widely used to secure data and information so that it is not easily misused by parties who are not interested in the data. One type of cryptographic algorithm is Caesar Cipher and Vigenere Cipher. Both of these algorithms are classic cryptographic algorithms that need to be modified so that they become more optimal in the data security process. The first modification is to modify the Vigenere key using Fibonacci. In general, Vigenere Cipher will repeat the same keyword to complete the number of characters that are lacking so that the number of characters is the same as the number of characters in the plaintext. The second modification is to change or convert plaintext letters into ASCII letters so that the code is more difficult to solve. After the ASCII conversion process is done, the next results will be converted back in Hexa letters. In addition to the two modifications made, the steganography technique is also added by hiding the code behind the media in the form of images. Images that are sampled will be renamed and stored in different places.</em>

<p>Nowadays, demands of data security are increasing, especially after introduction of wireless communications to the masses. Cryptographic algorithms are mainly used to obtain confidentiality and integrity of data in communication. There are a variety of encryption algorithms have been developed. This paper provides quantitative analysis and comparison of some symmetric key cryptographic ciphers (DES, 3DES, AES, Blowfish, RC5, and RC6).  The quantitative analysis approach is a step towards optimizing the security operations for an efficient next generation family of network processors with enhanced speed and power performance. A framework will be proposed as a reference model for quantitative analysis of security algorithm mathematical and logical operations.
