Storage over Internet Protocol (SoIP) is a technology framework that uses Transmission Control Protocol/Internet Protocol (TCP/IP) networks to link servers and storage devices and facilitate storage solution deployment. By combining the best storage and networking industry approaches, SoIP provides high-performance and scalable IP storage...
Triple Data Encryption Standard (DES) is a type of computerized cryptography where block cipher algorithms are applied three times to each data block. The key size is increased in Triple DES to ensure additional security through encryption capabilities. Each block contains 64 bits of data. Three keys are referred to as bundle keys with 56 bits per key. There are three keying options in data encryption standards:
Key option #3 is known as triple DES. The triple DES key length contains 168 bits but the key security falls to 112 bits.
Triple DES is advantageous because it has a significantly sized key length, which is longer than most key lengths affiliated with other encryption modes. However, the DES algorithm was replaced by the Advanced Encryption Standard by the National Institute of Standards and Technology (NIST). Thus, the Triple DES is now considered to be obsolete. Yet, it is often used in conjunction with Triple DES. It derives from single DES but the technique is used in triplicate and involves three sub keys and key padding when necessary, such as instances where the keys must be increased to 64 bits in length. Known for its compatibility and flexibility, software can easily be converted for Triple DES inclusion. Therefore, it may not be nearly as obsolete as deemed by NIST. Triple DES encrypts input data three times. The three keys are referred to as k1, k2 and k3. This technology is contained within the standard of ANSIX9.52. Triple DES is backward compatible with regular DES.
