What is CBC & ECB Cipher?

    CBC or ECB are modes of operation of a block cipher. Mode of operation is used to provide a way of encrypting arbitrary amount of data with a block cipher that by itself can encrypt only fixed block of data (e.g. 128-bits in case of AES). If you have anything else than 128 bits, you need to use a mode of operation.

Should ECB be used instead of CBC?

    I will say however that, while CBC has its own problems, ECB should never be used unless you are encrypting one block of data, which is 16 bytes for AES, otherwise this will happen. The important concept is called "malleability". CBC and CTR are very malleable.

What is the ECBC document?

    The document aims to guide and assist the building designers, architects and all others involved in the building construction industry to implement ECBC in real situations. The document is written both as a reference and as an instructional guide.

What is the ECB's CBPP?

    Concretely through the CBPP, the ECB purchases covered bonds, both in primary and secondary markets. The first two CBPPs, both one-year programmes, were implemented in 2009/10 and 2011/12 respectively. The third, CBPP3, began in October 2014, is ongoing and will continue until at least March 2017.
