Encryption is a procedure of coding data which can be a file or mail message into cipher text a form unreadable without a decoding key in order to avoid anyone except the pre-determined receiver from reading that information.Decryption is the reverse procedure of transforming encrypted data to its original unencoded ...

Data Encryption Standard (DES) is the block cipher which creates a fixed-length string of plaintext bits and change it through a sequence of complicated operations into another cipher text bit string of the similar length. It is a symmetric encryption technique which defines both sender and receiver need a shared ... Read More

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

Cryptography supports a number of security aims to provide the privacy of information, non-alteration of information and so on. Because of the high security benefit of cryptography it is broadly used today. There are the various goals of cryptography which are as follows −Confidentiality − Information in computer is sent ...

Cryptography is an automated mathematical tool that plays an important role in network security. It supports the confidentiality and integrity of information and provide authentication and non-repudiation to the users.Cryptography is frequently used in distributed applications to transfer recognition and authentication information from one system to another over a network. ...

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
