NIST IR 7298 Revision 1, Glossary of Key Information Security Terms
Private Key – A cryptographic key, used with a public key cryptographic algorithm,
that is uniquely associated with an entity and is not made public. In
an asymmetric (public) cryptosystem, the private key is associated
with a public key. Depending on the algorithm, the private key may
be used to—
1) Compute the corresponding public key,
2) Compute a digital signature that may be verified by the
corresponding public key,
3) Decrypt data that was encrypted by the corresponding public key,
or
4) Compute a piece of common shared data, together with other
information.

Private Key – A cryptographic key used with a public key cryptographic algorithm,
which is uniquely associated with an entity, and not made public; it is
used to generate a digital signature; this key is mathematically linked
with a corresponding public key.

Private Key – A cryptographic key, used with a public key cryptographic algorithm,
that is uniquely associated with an entity and is not made public.
SOURCE: FIPS 140-2
In an asymmetric cryptography scheme, the private or secret key of a
key pair which must be kept confidential and is used to decrypt
messages encrypted with the public key or to digitally sign messages,
which can then be validated with the public key.

Privilege Management – The definition and management of policies and processes that define
the ways in which the user is provided access rights to enterprise
systems. It governs the management of the data that constitutes the
user’s privileges and other attributes, including the storage,
organization and access to information in directories.

Privileged Account – An information system account with approved authorizations of a
privileged user.
