An entropy of n bits means that, on average, the attacker will try 2 n-1 passwords before finding the right one. We assume that the attacker knows the exact password generation method, including probability distributions for random choices in the method. Entropy is a measure of the average cost of hitting the right password in a brute force attack. The little boxes in the comic represent entropy in a logarithmic scale, i.e. Here is a thorough explanation of the mathematics in this comic:
Security at the expense of usability comes at the expense of security. We should remember this more often, AKA AviD's Rule of Usability: If our country was weak and the president could have been controlled from overseas, there wouldn’t be threats and the unrecognition of elections.”Įarlier, US Congressmen Steve Cohen (Democrat, Tennessee), along with Joe Wilson (Republican, South Carolina) introduced a Congressional Resolution to the House of Representatives to end recognition of Vladimir Putin as president of Russia if he remains in office beyond the end of his current term on May 7, 2024.I think the most important part of this comic, even if it were to get the math wrong ( which it didn't), is visually emphasizing that there are two equally important aspects to selecting a strong password (or actually, a password policy, in general):Īll too often, when discussing complex passwords, strong policies, expiration, etc (and, to generalize - all security), we tend to focus overly much on the computer aspects, and skip over the human aspects.Įspecially when it comes to passwords, (and double especially for average users), the human aspect should often be the overriding concern.įor example, how often does strict password complexity policy enforced by IT (such as the one shown in the XKCD), result in the user writing down his password, and taping it to his screen? That is a direct result of focusing too much on the computer aspect, at the expense of the human aspect.Īnd I think that is the core message from the sage of XKCD - yes, Easy to Guess is bad, but Hard to Remember is equally so.Īnd that principle is a correct one.
“Instead of aid and investments – sanctions and blockades, instead of peace and friendship – NATO approached our borders. “At the same time, Washington has not fulfilled a single promise made after the disintegration of the USSR,” the Duma speaker said. “Those who today approved resolutions, yesterday were delighted with (Mikhail) Gorbachev, applauded (Boris) Yeltsin,” the speaker pointed out, noting that then the Russians endured trials “because of the weakness of the country’s leadership and the betrayal of elites who were oriented not towards national interests at all.” For this, they need a change of power here,” he added. “They are doing everything to weaken us and then destroy. Such an initiative, according to the speaker, “yet again indicates that the US does not want a strong Russia.” The citizens of the Russian Federation will decide,” the Duma speaker added, TASS reported.Īccording to him, the resolution drafts to end Putin’s recognition as president being proposed in the US are “the best evaluation of the soundness of path and choice” made by the country’s citizens when they elected him as president. “Secondly, it’s not up to US congressmen to decide who can and who cannot be the president of our country.
“First of all, we do not meddle in American elections and one shouldn’t meddle in ours,” he wrote. He added that it’s not up to the US Congress to decide who will become Russia’s leader.
