strength of triple des

Rather than encrypting three times, you encrypt, decrypt, and encrypt again with different keys. Each block contains 64 bits of data. Strength of Triple-DES. AES uses keys of 128, 192 or 256 bits, although, 128 bit keys provide sufficient strength today. AES is the default algorithm on most systems. If a 128 bit triple DES key is created the amount of effective key bits - the bits actually used in the protocol - is 112 bits. International data encryption algorithm (IDEA) is a block cipher method similar to DES. Triple-DES is the extended version of DES which applies DES three times with two 56-bit keys. AES is the successor of DES as standard symmetric encryption algorithm for US federal organizations. It is vulnerable to key attack when a weak key is used. This is because there is one bit (the least significant one) in each byte assigned to create odd parity. Encryption and decryption takes the same algorithm. It uses 128 bit blocks, and is efficient in both software and hardware implementations. Triple DES will be kept around for compatibility reasons for many years after that. The key size is increased in Triple DES to ensure additional security through encryption capabilities. Triple DES has been endorsed by NIST as a temporary standard to be used until the AES was finished. From: stagda sys1 ic ncs com (Dave Stagner) Date: Thu, 13 Apr 1995 13:01:34 -0500 (CDT) As I understand it, triple-DES is not simply "three times stronger" than regular DES, but actually an order of magnitude stronger. The AES is at least as strong as Triple DES and much faster. Each block is encrypted in isolation, which is a security vulnerability. and changed all DES / Triple DES and RC4 ciphers to enabled=0x00000000(0) I've even added the Triple DES 168 key and 'disabled' it However my Nmap scan : $ -sV -p 8194 --script +ssl-enum-ciphers xx.xx.xx.xx Many security systems use both Triple DES and AES. It operates on 64-bit blocks of plaintext and uses a 128-bit key. Go for AES. Data Encryption Standard (DES) is the predecessor, encrypting data in 64-bit blocks using a 56 bit key. In cryptography, Triple DES (3DES) is the common name for the Triple Data Encryption Algorithm (TDEA) block cipher, which applies the Data Encryption Standard (DES) cipher algorithm three times to each data block. Triple DES: Triple DES is a encryption technique which uses three instance of DES on same plain text. Due to this design of Triple DES as an encrypt–decrypt–encrypt process, it is possible to use a 3TDES (hardware) implementation for single DES by setting K 1, K 2, and K 3 to be the same value. However double DES uses 112 bit key but gives security level of 2^56 not 2^112 and this is because of meet-in-the middle attack which can be used to break through double DES. Advantages: 1. its a 56 bit key. The algorithm is believed to be practically secure in the form of Triple DES… In January 1999 distributed net and the Electronic Frontier Foundation (EFF) collaborated to publicly break a DES key in 22 hours and 15 minutes. Second variant of Triple DES (2TDES) is identical to 3TDES except that K 3 is replaced by K 1. The AES block cipher is rather more secure than triple DES. Triple Data Encryption Standard (DES) is a type of computerized cryptography where block cipher algorithms are applied three times to each data block. Triple DES extends the key length of DES by applying three DES operations on each block: an encryption with key 0, a decryption with key 1 and an encryption with key 2. Template:Infobox block cipher. So there are 2^56 possibilities of keys which would take a decade to find the correct key using brute-force attack 2. This provides backwards compatibility with DES.
