The answer is d it is d it is d I think I think, I’m not sure though
Answer:
64 byte.
It's not bit is byte.
Explanation:
Secure Hash Algorithms (SHA) :- These are a family of cryptographic hash functions. There are basically four types of secure hash algorithms for generating cryptographically secure one-way hash.They are as following:-
SHA-0
SHA-1
SHA-2
SHA-3
SHA -2 consists of SHA-512 and the block size used by it is 64 byte or 512 bits.
The answer is : Ka=0.000137
HA -> H+ + A-
0.10 x x
0.10-x +x +x
[H+]= 10^-2.44 = 0.00363
x= 0.00363
(0.00363)(0.00363)/(0.10-0.00363) = 0.000137
Ka=0.000137
Authentication protocols are usually designed and configured to create a number that will be used only once, so as to prevent replay attacks in a computer network. Thus, this number is called a <u>nonce</u>.
Authentication work based on the principle of strategically matching an incoming request from an end user or electronic device to a set of uniquely defined credentials.
In an access control list (ACL), authentication and authorization is used to ensure an end user is truly who he or she claims to be, as well as confirming that an electronic device is valid through the process of verification.
In Cybersecurity, authentication protocols are usually designed and configured to create a nonce, which can be used only once, so as to prevent replay attacks in a computer network.
In conclusion, a nonce is used prevent replay attacks in a computer network because the number created by an authentication protocol can be used only once.
