TDES stands for Triple Data Encryption Standard. It is upgraded or improved version of DES (Data Encryption Standard) which is a symmetric cryptographic approach in which DES is used to each block three times which scrambles the plain text to cipher text.TDEA provides key size of 56, 112, 168 bits ...

Suspicious email detection is a type of mailing system where suspicious users are recognized by deciding the keywords used by him. The suspicious keywords are discovered in the mails which are sent by the user. All the blocked mails are tested by the management and recognize the users who have ... Read More

Triple DES Algorithm used by admin to encode the messages sent to the users or sent some warnings about the different user’s suspicious event. In this research, suspicious words dictionary can be used to find the suspicious words which are not generally used in the normal messaging or communication.There are ... Read More

Triple DES is also called a TDES. It is a symmetric key block cipher, defining that the same key can be used to encrypt and decrypt information in fixed-length set of bits known as blocks. It is known as "Triple DES" because it uses the DES cipher three times when ... Read More

The Double DES uses two example of DES cipher for encryption and two units of reverse DES cipher for decryption. Each unit of DES cipher needs multiple key for encryption which enhance the size of the key (112 bit) creating it more secure. But in the double DES can be ... Read More

Data Encryption Standard (DES) is a block cipher algorithm that takes plain text in blocks of 64 bits and transform them to ciphertext utilizing keys of 48 bits. It is a symmetric key algorithm. It can define that the same key can be used for encrypting and decrypting data.The design ... Read More

The Data Encryption Standard (DES) is a symmetric key block cipher which creates 64-bit plaintext and 56-bit key as an input and makes 64-bit cipher text as output. The DES function is create up of P and S-boxes. P-boxes transpose bits and S-boxes substitute bits to make a cipher.DES is ... Read More

DES is a block cipher. The encryption procedure is create of two permutations (Pboxes) that it can be defined initial and final permutations, and 16 Feistel rounds. Each round need a different 48-bit round key created from the cipher key according to a pre-represented algorithm. The DES function uses a ... Read More

There are two main variations of Data Encryption Standard are as follows −Double DES − Double DES is an encryption approach which need two instance of DES on same plain text. In both instances it uses multiple keys to encrypt the plain text. Both keys are needed at the time ... Read More

There are various elements of DES which are as follows −Use of S-Boxes − The tables used for substitution i.e., the S-boxes, in DES are kept hidden by IBM. IBM supports that it took them over 17 person years to appear up with the internal design of the S-boxes.Key Length ... Read More
