Assume I have a function encrypt(mes,key) where mes is the message, and key is the key. The length of key is 64 bits. Last but not least: assume the only way to crack my cipher is a brute-force ...
On the surface, the inadvisability of security through obscurity is directly at odds with the concept of shared secrets (i.e. "passwords"). Which is to say: if secrecy around passwords is valuable, ...
Note: this question arises purely from a theoretical interest in security research. Frequently in popular fiction we see white-hat hackers decrypt secret information in a matter of seconds. While ...
Cryptographic primitives usually assert some security level given as number of operations to mount an attack. Hash functions, for example, give different security levels for collision attacks, ...
I'm not so bad at mathematics: I know what are p-list and p-combinations, I know matrix algebra, I know what a XOR is, I know how to tell if number is a prime, etc: I'm not the programmer who hates ...
Schneier's law (which should probably be called Babbage's Law). States that: Anyone, from the most clueless amateur to the best cryptographer, can create an algorithm that he himself can't ...
