SSL - TLS White Papers
SSL Offloading Solutions
Overview
Since its inception in 1995, SSL or Secure Socket Layer has been the
standard protocol for providing critical security services to Internet users
worldwide. SSL encompasses multiple cryptographic algorithms of
varying strengths, making it appropriate for use in both domestic and
export scenarios simply by manipulating the supported ciphers. SSL
version 3.1 and TLS version 1.0 are different names for the same
protocol; when this document uses the term “SSL” it refers to SSLv3.0 or
TLSv1.0.
In addition to encrypting data or providing confidentiality, the
characteristic for which it is best known, SSL also offers message
integrity, authentication, and key exchange services. Although SSL neatly
comprises these four security services, they are actually offered by three
to four distinct mechanisms within SSL. Confidentiality is offered by
symmetric ciphers, or shared-secret key cryptography. This sort of
cryptography is very fast, not very computationally demanding, and uses
a single key for both encrypting and decrypting data. Symmetric ciphers
used by SSL include DES, 3DES, RC2, and RC4 and can range in
strengths from 40 bits to 168 bits.
