Quite simply, the act of selling over the internet. This can either be Business to Business (B2B) or Business to Consumer (B2C). Also known as E-business or E-tailing.
El Gamal Algorithm
An algorithm for asymmetric cryptography that was invented by Taher el gamal, founded on the challenge of calculating discrete logarithms and can be used for both encryption, like 128-bit encryption and SSL encryption, and digital signatures, used in digital certificates like SSL digital certificates and 128-bit certificates for internet security and network security with secure authentication and secure SSL authentication.
Electronic codebook (ECB)
Block cipher mode that consists of simply applying the cipher to blocks of data in sequence, one block at a time. It does not use feedback, and is also considered the weakest form of block cipher.
Elliptic Curve Cryptography (ECC)
It represents a different way to do public-key cryptography - an alternative to the older RSA system - and also offers certain advantages. ECC devices will require less storage, less power, less memory and less bandwidth - ultimately a more efficient cryptosystem. This allows the implementation of cryptography in platforms that are constrained, such as wireless devices, handheld computers, smart cards and thin-clients. It also provides a big win in situations where efficiency is extremely important, such as on a bottlenecked web server supporting e-commerce
Encryption is the process of changing data into a form that can be read only by the intended receiver. To decipher the message, the receiver of the encrypted data must have the proper decryption key. In traditional encryption schemes, the sender and the receiver use the same key to encrypt and decrypt data. Public-key encryption schemes use two keys: a public key, which anyone may use, and a corresponding private key, which is possessed only by the person who created it. With this method, anyone may send a message encrypted with the owner's public key, but only the owner has the private key necessary to decrypt it.
Encryption at the point of origin in a network, followed by decryption at the destination
