I-FLY WIRELESS ROUTER ADSL
•MD5: A one-way hashing algorithm that produces a 128-bit hash.
•SHA-1:A one-way hashing algorithm that produces a 160-bit hash.
•Encryption: Select the encryption method from the pull-down menu. There are four options, DES, 3DES, AES and NONE. NONE means it is a tunnel only with no encryption. 3DES and AES are more powerful but increase latency.
•DES: Stands for Data Encryption Standard, it uses 56 bits as an encryption method.
•3DES: Stands for Triple Data Encryption Standard, it uses 168 (56*3) bits as an encryption method.
•AES: Stands for Advanced Encryption Standards, it uses 128 bits as an encryption method.
Perfect Forward Secrecy: Choose whether to enable PFS using Diffie-Hellman publickey cryptography to change encryption keys during the second phase of VPN negotiation. This function will provide better security, but extends the VPN negotiation time. Diffie- Hellman is a public-key cryptography protocol that allows two parties to establish a shared secret over an unsecured communication channel (i.e. over the Internet). There are three modes, MODP 768-bit, MODP 1024- bit and MODP 1536-bit. MODP stands for Modular Exponentiation Groups.
Pre-shared Key: This is for the Internet Key Exchange (IKE) protocol, a string from 4 to 128 characters. Both sides should use the same key. IKE is used to establish a shared security policy and authenticated keys for services (such as IPSec) that require a key.
Before any IPSec traffic can be passed, each router must be able to verify the identity of its peer. This can be done by manually entering the pre-shared key into both sides (router or hosts).
