Cryptography is the art and science of encoding and decoding (enciphering/deciphering) data so that outside parties cannot decode the data. High-level functions enabled through the use of cryptography include the following:

  • Confidentiality of information during storage and transmission
  • Authenticationof users and received/retrieved information
  • Integrity of data
  • Non-repudiation of transactions
  • Availability of data and resources
  • Controlled access to information and resources

Network security protocols and applications use a variety of cryptographic algorithms to achieve these high-level goals. Because cryptography is computationally intensive, hardware acceleration is highly desirable when cryptographic algorithms are frequent system functions.

A month later, and the link is still broken. EETimes, if you are going to pull the paper, at least notify your users, instead of having us go to the trouble of trying to download.
