DES

Abbreviation for "Delivered Ex Ship."

Delivered Ex Ship

In international commerce, an agreement between a buyer and a seller in which the seller must bear all costs and risks of transporting a good until it has arrived at a port and has been made available for the buyer or his/her agent to retrieve it. That is, the seller has total responsibility while the good is being shipped overseas. The seller must pay the shipping company and purchase insurance for the good. See also: Incoterm.

Thus stream cipher is well suited for burst switching compared to the block cipher.
recently announced that CLEFIA, the block cipher algorithm it developed and presented as a state-of-the-art cryptography technique in 2007, has been adopted as one of the ISO/IEC 29192 International Standards in lightweight cryptography after the final approval of ISO (International Organization for Standardization)/IEC (International Electrotechnical Commission).
Generally, stream cipher is used in environment where encryption need to be done in a continuous stream of bits (rather than by block as in block cipher).
As an example, the IEEE802.15.4 radio, which is vastly popular for wireless sensor and actuator networks, uses the 128-bit Advanced Encryption Standard (AES) block cipher. The cipher is operated with a symmetric (shared private) key to encrypt frames at the link layer for data secrecy, and combined with nonces (number used once) to provide source authentication between conversing nodes.
