  Madryga - Wikipedia, the free encyclopedia
In his proposal, Madryga set forth twelve design objectives that are generally considered to be good goals in the design of a block cipher.
Madryga met the objective of being efficient in software: the only operations it uses are XOR and rotations, both operating only on whole bytes.
Perhaps Madryga's fatal flaw is that it does not exhibit the avalanche effect.

 Opracowania - Ewa Karasińska - Jan Kochanowski: "Srogie łańcuchy na swym sercu czuję"
Madrygał to gatunek poezji lirycznej, ukształtowany we Włoszech, gdzie początkowo (XIV w.) pojawił się jako pieśń pasterska zwana pastorellą, a później (XVI w.) jako pieśn miłosna.
Madrygał włoski XV i XVI wieku był wierszem – strofą złożoną z trzech (lub dwóch) tercetów o dowolnym układzie rymów oraz z dwóch (czasem jednego) kupletów; zwykle pojawiały się w nim 11 i 7-zgłoskowce swobodnie przeplatane.
Madrygał był ściśle związany z przekazem muzycznym, a samodzielną realizację zyskał tylko w poezji Jana Kochanowskiego.

The original suggested choice of parameters were a block size of 64 bits, a 128-bit key and 12 rounds.
RC5 makes extensive use of data-dependent rotations, a relatively unusual cryptographic operation — they were used previously only in Madryga — and combines them with modular addition and eXclusive OR (XOR) in a Feistel-like network.
The encryption and decryption routines can be specified in remarkably few lines of code, though the key schedule is more complex.

 CBC News: Vancouver basks in record sunshine
However, the warm daytime temperatures are taking their toll on ski hills — with the worst snowpacks in 30 years on the South Coast mountains.
Dagenais says the cooler temperatures at night have allowed the resort to produce snow artificially, and he notes a fresh dusting of natural snow is expected next week.
Meanwhile, Madryga says he's worried that Vancouver will "pay for this" sun with a stretch of rainy weather, but he's just not sure when.

 Cryptanalysis - Wikipedia, the free encyclopedia
Kahn may have been premature in his cryptanalysis postmortem; weak ciphers are not yet extinct.
In academia, new designs are regularly presented, and are also frequently broken: the 1984 block cipher Madryga was found to be susceptible to ciphertext-only attacks in 1998; FEAL-4, proposed as a replacement for the DES standard encryption algorithm, was demolished by a spate of attacks from the academic community, many of which are entirely practical.
In industry, too, ciphers are not free from flaws: for example, the A5/1, A5/2 and CMEA algorithms, used in mobile phone technology, can all be broken in hours, minutes or even in real-time using widely-available computing equipment.

 Agiliti launches remote management offering
AHL's desire to lower costs while retaining ownership of its equipment "played into our decision" to extend the relationship with Agiliti, said Mary Madryga, vice-president of technology at AHL.
Madryga could not specify the monthly cost savings she anticipates through the remote services agreement with Agiliti.
But one of the benefits of the deal, she said, is that the remote monitoring services prevent AHL from "having to invest in infrastructure across our entire client base".

Companies like AHL Services Inc., a Virginia based provider of marketing support services to Fortune 500 companies, uses MSPs to monitor transactions and data that cross a wide-area network hub to 25 "touch points" with AHL's customers.
Mary Madryga, vice president of technology, noted that the relationship with the MSP has helped lower infrastructure costs while allowing them to retain ownership of its equipment.
Another benefit, noted Madryga, is that the remote management services prevent her company from "having to invest in infrastructure across our entire client base."
