![]() But he would eventually headline a major franchise – namely, the 007 films. He was first bitten by the acting bug at the age of six, when he made his debut in a primary school production of the musical “Oliver.” As an adult, Craig would initially be hired for supporting roles on the big screen. Understanding risk and reward is the final truth of security engineering – that, and never working with family.British actor Daniel Craig recently appeared on Broadway in “Macbeth” opposite Ruth Negga as his queen. We also don't create secrets that attract attention four hundred years later. Motivation, resources and good old-fashioned people politics count for just as much as careful application of innovative tech.įortunately for most of us, we don't literally risk our necks or the fate of nations when we make security decisions. The equation of how much of what sort of security to employ, when and how, depends not only on the quality of the tools but the value of the data, the motivation and resources of those who would defeat that security, and the degree to which that security impedes your intentions. This encapsulates so many rules of data security in the real world. What kept Mary alive was her circumspection, but that also limited what she could do. Mary's crypto was weak and she operated in the most hostile of environments, but even so her opponents relied heavily on compromising humans. In the end, though, if you're getting nowhere, you take a punt. The excitement of finding and decoding them was not justified by their contents: Mary must have known that the resources of the English state were equal to her defences. Mary had previously been careful in what she wrote, even via ostensibly secure channels, as the recent publication of a new cache of her secret letters shows. One with letters in a known cipher wrapped in a leather pouch and hidden in the bung of a beer barrel delivered to Mary's prison – a combination of encryption, packetisation and steganography. In the end, Mary sealed her fate by authorizing a plot to usurp Elizabeth using a channel compromised, in fact controlled, by Walsingham. Will there be no end to govt attempts to break encryption?

Alas, they weren't to be invented for another 300 years. ![]() Conversely, the poor cipher used to try and hide the content of messages could have been rendered totally uncrackable, even at the time, by one-time pads, which just need dice, paper and pencil. The problem of knowing whether a message has been intercepted has only just been decisively solved by quantum encryption, a system sadly unavailable in the mid-16th century. One of the key technologies of the time was letter locking, a form of anti-tamper origami, with increasingly clever locks testing the technicians of the Black Chamber, the Tudor Bletchley Park, whose job was to invisibly defeat them once intercepted. It had some strength, the real issue was channel vulnerability.īy use of double agents and control of messengers, Elizabeth's security chief Sir Francis Walsingham could intercept and duplicate messages before passing them on as apparently untouched. It was vulnerable to frequency analysis, as enciphered text kept a similar fingerprint count of vowels and consonants as the clear text, and contextual identification of symbols that referred to specific people. The system that finally sealed Mary's fate had the best crypto of the time, a mixture of letter transposition and symbol substitution. ![]()
