This is copyrighted material we can not use it. That said, I feel it is an
important part of the education process to define terms for those who do not
yet speak the language - the language in this case is security. I provide
this as an example of what I have in mind for the site.
What I had in mind was this, that anytime a "security word" appears in
documents that we produce as a part of this project that a person can click
on that "security word" and the definition will pop up in a little window
much the way that the bio's do now.
Any thoughts from the group?

>
> asymmetric cryptography
> -----------------------
> A class of cryptographic algorithms that use separate keys for encryption
> and decryption. [2]
>
> attack

> biometric device

> A device that authenticates people by measuring some hard-to-forge physical
> property, like a fingerprint or the strokes and timing of a signature
> biometrics Using physical characteristics of users such as fingerprints and
> retinal impressions to authenticate users. [2]
>
> buffer overflow
> ---------------
> This happens when more data is put into a buffer or holding area, then the
> buffer can handle. This is due to a mismatch in processing rates between the

>
> digital signature
> -----------------
> Digital signatures are used to detect unauthorized modifications to data and
> to authenticate the identity of the signatory. In addition, the recipient of
> signed data can use a digital signature in proving to a third party that the
> signature was in fact generated by the signatory. A digital signature is
> represented in a computer as a string of binary digits. A digital signature
> is computed using a set of rules and a set of parameters such that the
> identity of the signatory and integrity of the data can be verified. An
> algorithm provides the capability to generate and verify signatures.
> Signature generation makes use of a private key to generate a digital
> signature. Signature verification makes use of a public key, which
> corresponds to, but is not the same as, the private key. Each user possesses
> a private and public key pair. [6]
>

> A cryptographic one-way function that takes an arbitrary-sized input and
> yields a fixed-size output [1]
