What is Meant by Security of VPN Encryption?
Usually, VPNs are advertised as facilities for online security. VPNs, however, are different from each other. VPN security largely depend on the encryption used. When they are asked "What is meant by security of VPN Encryption?" people almost instantly think about levels of encryption. But there is another element just as important – the encryption protocols. To be better secured, consider a VPN in VPN form which offer encryption protocol with encryption level choices for the specific activity you are engaged in.
The Meaning of VPN Encryption Protocol
Encryption protocols, also termed as cryptographic protocols, determine the process to be used in the encryption. Different data forms like files or web pages need different protocols which operate at various levels of IP network. Ordinary internet users may only need encryption that protects data from its source to its destination for adequate security. IPSec is an example, which is an encryption protocol that does end-to-end encryption and secures any application traffic. To protect specific applications in forms like email, VoIP communications or web pages, SSL is being used by OpenVPN. NSA is also rumored to have the ability to access encryption keys secretly, so be wise in choosing.
The Meaning of VPN Encryption Level
Encryption level is related to the degree of strength of data encryption. Usual levels are 256-bit and 128-bit. These terms denote the length of the encryption key to be used, and therefore indicate the degree of difficulty in breaking because of many probable combinations. Speed is another factor here. Decline in the speed of user's connection occurs necessarily with high encryption levels. This is caused by the time spent in coding and decoding data and in sending larger, highly encrypted files. If the data flow takes a longer time, the chances for the data to be decoded and intercepted is also greater. Larger files also indicate a massive volume or very important data so snoopers aim for them. Thus, for majority of activities, 128-bit level of encryption is adequate for data protection. Sensitive data in small sizes such as credit card numbers may use 256-bit level. The resulting file will be of a size not sufficient to raise flags. With being on VPN service nobody gets to see the website that you are having communication with. source
