smartphones tracking users

The fact that most of us carry (voluntarily) a tracking device should not be news for anybody. I guess the news-worthy part is that somebody expossed what Apple and Google where doing. I am not sure it is illegal, have you checked the small font bits of the contract you signed? Me neither.
Believe me, that Apple and Google know where you are and where you have been is not the biggest of our problems with privacy as discussed in here.

Brute Force Attacks
Assuming, as Kerchoff’s principle recommends, that the algorithm used for encryption and the general context of the message are known to the cryptanalyst, the brute-force attack involves the determination of the specific key being used to encrypt a particular text. When successful, the attacker will also be able to decipher all future messages until the keys are changed. One way to determine the key entails exhaustive search of the key-space (defined as the set of all possible valid keys for the particular crypto-system).
Brute force is a passive, off-line attack in which the attacker Eve passively eavesdrops the communication channel and records cipher text exchanges for further analysis, without interacting with either Alice or Bob.
To estimate the time that a successful brute-force attack will take we need to know the size of the key-space and the speed at which each key can be tested. If is the number of valid keys and we can test keys per second, it will take, on average seconds to find the proper key by brute-force.
The threat that a brute-force attack poses cannot be underestimated in the real world. Most financial institutions use cipher-systems based on DES. Keys of length 56-bits, such as the one used by the
standard implementation of DES, can be obtained by brute-force using computer hardware and software available since the late 1990′s. Indeed, to counter this possibility, most contemporary implementations of DES use a derivative known as Triple-DES (or 3-DES) which uses three different 56-bit keys instead of one. The effective key length for the combined 3-DES key is a more secure 168 bits.
Brute force analysis have been used in combination with other attacks as was the case for the deciphering of the Enigma. The famous bombes were an example of the brute-force approach working in combination with a mathematical method that provided an important reduction of the key-space.

To be continued…..

Canada’s telecom regulator said Friday it will not expand its probe into Internet pricing to look at the billing practices of retail Internet services because market forces are working just fine for consumers.

A related editorial, explains why this is the right approach.

A “Free” internet does not mean that users should not be paying market prices for connectivity or services.

See my previous post.

Regulators are congenitally incapable of grasping that they create more problems than they solve

This is why I am always wary of attempts at regulation.
