Privacy - Digital Signature, ID & Authentication
- File containing August 1992 text of a letter
Computer Professionals for Social Responsibility (CPSR) recently sent to
Rep. Jack Brooks, chairman of the House Judiciary Committee. The letter
raises several issues concerning computer security and cryptography
policy, including digital signature.
- File containing NIST's August 1991 notice requesting
comments on a proposed Federal Information Processing Standard (FIPS) for
Digital Signature Standard (DSS). This proposed standard
specifies a public- key based digital signature algorithm (DSA)
appropriate for Federal digital signature applications. The proposed
DSS uses a public key to verify to a recipient the integrity of data and
the identity of the sender of the data. The DSS can also be used by a
third party to ascertain the authenticity of a signature and the data
associated with it.
- File containing August 1991 announcement by
NIST of the proposed Digital Signature Standard (DSS). This standard
specifies a Digital Signature Algorithm (DSA) which can be used to
generate a digital signature. Digital signatures are used to detect
unauthorized modifications to data and to authenticate the identity of
the user who generates the signature. 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 signer of the data. This is
known as nonrepudiation since the signer of data cannot, at a later time,
repudiate the signature.
- On January 31, 1992, NIST published in the Federal
Register a proposed Secure Hash Standard (SHS) designed to
work with the proposed DSS. This is a copy of the
proposed standard's announcement section, technical
specifications and appendix A.
- January 1992 draft of the specifications for a
secure hash standard (SHS) designed to
work with the proposed DSS.
- The National Institute of Standards and Technology
(NIST) has proposed a public key-based Digital Signature Standard (DSS).
This CSL Bulletin provides agencies with information regarding the
proposed standard and describes several applications which may benefit
from the DSS.
- File containing statement of
Raymond Kammer, Acting Director, National Institute of Standards and
Technology, before the House Subcommittee on Telecommunications and
Finance (Committee on Energy and Commerce), on April 29, 1993. Kammer
discusses NIST's activities in telecommunications security, the planned
recertification of the Data Encryption Standard, the proposed Digital
Signature Standard, and the Clipper Chip.
