WebSep 3, 2016 · A pair of researchers from INRIA have identified a new technique called Sweet32. This attack exploits known blockcipher vulnerabilities (collision/birthday attacks) against 64-bit block ciphers like 3DES and Blowfish. It affects any protocol making use of these “light” blockciphers along with CBC-mode for a long period of time without re-keying. WebThe new attack combines linearization and generalized birthday attacks and thus, is faster than all these attacks. Furthermore, both algorithms are slightly improved. This leads to …
