Last week I wrote about Linux developers evaluating a new "DOITM" security mitigation for the latest Intel CPUs. While the cost for now of engaging the Data Operand Independent Timing Mode (DOITM) functionality is minimal, following internal Int...
Anyone can design a cipher that he himself cannot break. This is why you should uniformly distrust amateur cryptography, and why you should only use published algorithms that have withstood broad cryptanalysis. All cryptographers know this, but non-cryptographers do not. And this is why we repeatedly see bad amateur cryptography in fielded systems.
Critical vulnerabilities in a market-leading line of digital locks securing hospitals, airports, and water treatment facilities makes it possible for rogue employees or outside attackers to clone digital keys, researchers reported late last week.
SSL and its successor, TLS (Transport Layer Security), which encrypt data exchanged between two machines, are at the heart of web security. Signified by "https" in the browser URL, they underpin almost all Web transactions that requires privacy
