Public keys increase the level of security in authenticating users and allow the use of authentication options like smart cards and other physical devices.
The Diffie-Hellman key agreement mechanism is a well-understood and widely implemented public key technique that facilitates cost-effective cryptographic key agreement across modern distributed electronic networks such as the Internet.
The security of this type of cryptosystem rests on finding a mathematical procedure to generate two complementary keys such that knowing just the public key and the encryption method is not enough to deduce the private key.
Other security products offered are Triple-DES, security hashing, and public key accelerators.
Symmetric key cryptography is used to encrypt each packet instead of public key cryptography because it is considerably less computationally intensive.
In the RSA scheme, the secret key consists of two prime numbers that are multiplied together to create the lengthier public key.
