The Types And Disadvantages Of Asymmetric Encryption

PUBLIC KEY (ASYMMETRIC) ENCRYPTION
Asymmetric Encryption is used to protect the data while in movement. Asymmetric Encryption is also known as Public Key Encryption. It uses two related keys, a public key and a private key which is not shared with anyone. This pair of keys are developed by mathematical methods which can be solved in one direction. So anyone can encode a data using the public key but only the user with a private key can decode that specific data. The length of Asymmetric Key Encryption is normally 1024 or 2048 bits. However, in Asymmetric framework the keys with smaller than 2048bits are considered as not safe to use.
Asymmetric Key Encryption methods are DSA, Diffie Hellman, RSA, Elliptic Curve and DSA. Asymmetric Encryption …show more content…

To oppose this issue the keys should be delivered by trusted software or entity.
ESCROW KEY
This type of encryption key administration is to create an extra key for decoding the data and is kept secure in escrow by an authorised 3rd party. We can also call this as a backup key or split-key. This kind of encryption method is been using to recover the data if a user forgot the password.
In July 2015, many of the world’s high ranking cryptographers published that the loss and destruction induced by adopting a key escrow system 20 years ago would be even more serious, that would be very hard to identify security weaknesses that could be misused by …show more content…

So generally the data is not readable to unauthorized users. This is the process of encrypting the data which is stored and residing on our devices.

End to End Encryption
In this process of end to end encryption, the unauthorized users such as service provider or any intermediate person can’t decrypt or read the communication between the sender and receiver. In the present day, Service Providers have access to our communication but when we deploy the end to end encryption then the service provider can intercept the communication but can’t read the content of our communication and the common example is WhatsApp messaging service. We can also secure our emails by using PGP encryption technology.

Transport Encryption
This process is a transport layer encryption that includes HTTPS using TLS/SSL which is used to encrypt and keep secure the communication between the websites and the web browser. The websites with HTTPS, enable us to transmit the information over the internet securely. Even if unauthorized user access that information, they can’t read. When the information reaches to the destination probably located in a different country, then website operator can decrypt it and store it.
