Click on the arrows to vote for the correct answer
A. B. C. D.B.
Out of the given options, the encryption algorithm that would meet the requirement of supporting remote access over IPSEC is B. AES (Advanced Encryption Standard).
IPsec (Internet Protocol Security) is a protocol suite used to ensure secure communication over an IP network. It provides security services such as authentication, confidentiality, and integrity of the data being transmitted. One of the primary components of IPsec is the use of encryption algorithms to secure the data.
AES is a symmetric encryption algorithm that is widely used for securing data transmissions. It is considered one of the most secure encryption algorithms and is widely used in various security protocols. AES supports different key lengths of 128, 192, and 256 bits, and the key length determines the level of security provided.
MD5 (Message Digest 5) is a cryptographic hash function used for integrity checks, not encryption. It produces a fixed-length 128-bit hash value from the input message, which is used to verify that the message has not been tampered with.
UDP (User Datagram Protocol) is a transport protocol used to send data over an IP network. It does not provide any encryption or security services.
PKI (Public Key Infrastructure) is a system that uses public key cryptography to enable secure communication. It involves the use of a trusted third party, called a Certificate Authority (CA), to issue digital certificates to users and devices. PKI is not an encryption algorithm, but rather a system for managing digital certificates and enabling secure communication.
In summary, out of the given options, AES is the encryption algorithm that would meet the requirement of supporting remote access over IPSEC.
