A8 algorithm can be used to generate 32 bit SRES from 128 bit secret key and 128 bit RAND.(True or False)

To authenticate MS, the MSC needs to send SRES to MS for verification.(True or False)

Homework Answers

Answer #1

Ques:A8 algorithm can be used to generate 32 bit SRES from 128 bit secret key and 128 bit RAND.

Ans:False

Reason: Because when RAND and secret key are input into the A8 encryption algorithm. The output is the 64 bit kc.

Kc is the session key of encryption.

Ki is the authentication ​​​​​​​​​​​

Ques: To authenticate MS, the MSC needs to send SRES to MS for verification.

Ans: True

Description: The RAND and the ki are inputted into the A3 encryption algorithm. The output is 32 bit SRES. The SRES is 'challenge' sent to the MS when authentication is required.

NWS620S Tutorial 1: Symmetric Encryption - DES Encryption is the translation of data into a secret code so that only authorised entities can read it. Encrypting data is considered a very effective way of achieving data security. To access encrypted data, you must have access to a secret key that enables you to decrypt it. Unencrypted data is called plain text; encrypted data is referred to as cipher text. There are two types of encryption: • Symmetric encryption • Asymmetric...

1. Aspartate is metabolized to oxaloacetate, which we know via gluconeogenesis can be used to generate PEP. Assuming the PEP then proceeds to pyruvate and acetyl CoA and enters the citric acid cycle, how much ATP could be generated from the complete oxidation of Aspartate if we assume 1 NADH produces 3 ATP, 1 FADH2 produces 2 ATP, and GTP or ATP are equivalent (1GTP=1ATP). (Also ignore the “cost” of Nitrogen removal; don’t consider the urea cycle) 2. True or...

A state's Department of Motor Vehicles needs a program to generate license plate numbers. A license plate number consists of three letters followed by three digits, as in CBJ523. (So "number" is a bit inaccurate, but that's the standard word used for license plates). The plate numbers are given out in sequence, so given the current number, the program should output the next number. If the input is CBJ523, the output should be CBJ524. If the input is CBJ999, the...
