This is an example of the importance of key management. Two devices wishing to establish a VPN session send encryption keys in plaintext at the beginning of the session. If this were the case, then an attacker snooping on the keys could use them to decrypt the ciphertext into readable plaintext, which would result in a loss of confidentiality within the VPN.Act, designed to meet future security needs. SuiteB has been approved for protecting confidential information at the Secret and Top Secret levels. Cisco was involved in the development of some of these standards. SuiteB Next-GenerationEncryption (NGE) contains algorithms for authenticated encryption, digital signatures, key establishment, and cryptographic hash computation, as follows.Elliptic Curve Cryptography (ECC) replaces the RSA signature with the ECDSA algorithm and the DH key exchange with ECDH. ECDSA is an elliptic curve variant of the DSA algorithm, which has been the standard since 1994. The new key exchange uses a DHO containing P-256 and P.384 curves AESO in GaRobin/CounterMode (GCM) operationECC digital signature algorithm. SHA-256, SHA-384, and SHA-512O6.2.8 IPSec and SSLThe IPSec protocol is a set of protocols that have been used to protect IP packets for decades. Today, it is used in both remote-access VPNs and site-to-site VPNs, and the OSSL protocol is a "new face" in remote access VPN applications. Let's examine these two protocols.1. IPSecIPSec is a set of protocols and algorithms for protecting IP packets at Layer 3, hence the name IP Security (IPSec). o The main advantages of IPSec are: confidentiality through encryption; data integrity through hashing and HMAC; and the use of digital signatures or Pre-SharedKey (PSK) (similar to a VPN), IPSec also supports anti-replay functionality. A brief description of the various IPSec components (protocols, algorithms, etc.) is shown below.
