I know that
In cryptography, the linearization attack is a method of cryptanalysis
for block ciphers
I am looking for an example of linearization attack couldn’t find it online
Could anyone please explain it with an … Continue reading What is linearization attack [migrated]
I want to start off by saying that I am not an expert in regards to networking or Wireshark but I do have a background in web development, particularly .net and iis/windows server.
I am trying to add a couple of ciphers in … Continue reading Expected Cipher Suites not showing in packet traces – Handshake Failure [migrated]
Let’s say that a substitution cipher had 52 symbols instead of 26. For this, we would include all lower case and upper case letters. This creates a key space of 52! wehere the cipher text can contain both lowercase and upperc… Continue reading Does adding more letters provide added security compared to a standard substitution cipher?
I am a newbie to block cipher and when learning the CBC mode, I start to understand that an IV is being used in this mode and also will be transferred to the message receiver.
So here is my question, what if the IV is tampered? CBC mode … Continue reading What if the attacker tamper the IV used in the block cipher CBC mode?
This question is similar to this one, so let me elaborate what I’m struggling with.
I want to get the length/strength of the key used by the server during the key exchange and authentication, i.e. public key size for RSA, pr… Continue reading TLS key exchange and certificate subject public key clarification

Is there any cipher suites supported in one TLS version and not supported in the other? If yes, then is there any documentation that talks about the cipher suites supported in each TLS or SSL versions?
