Apart form the following, are there any other standard properties that a cryptographic Substitution box or the S-Box should have:
Changing one input bit should change about half of the output bits.
Each output bit should depend on every … Continue reading What are the standard properties of an S-Box [migrated]
I have observed that once we save our card on our Google Play account to make a purchase via the Google Play store or apps like Udemy, the payments do not require any OTP/PIN from the bank or the card password from the user to be entered. … Continue reading Why Credit/Debit card saved to Google Play account does not require OTP or Password for the payment [closed]
L. Cuccovillo in his paper Audio tampering detection via microphone classification talks about identification of the uniqueness in the output generated by the microphones which can act as a fingerprint for the device.
What are the possi… Continue reading What are the various defense mechanisms against audio fingerprinting
I was going through one of the articles on camera fingerprinting that says that
using most basic Instagram or Snapchat filters will not get rid of the
camera fingerprint. However, changing the resolution, which most
social media si… Continue reading Digital Camera Fingerprinting via Instagram and Snapchat
In a cryptography algorithm such as AES or DES, does the number of rounds mean same as iterating the algorithm?
Example:
c= “plaintext”;
for(int i=0;i<5; i++)
{
c = AES(c , “key”);
}
Where c holds the cipher text produced after 5 … Continue reading Is rounds in a cryptography algorithm same as iterating the algorithm?
