IEEE Standards documents are developed within the IEEE Soc
7、ieties and the Standards Coordinating Committees of the IEEE Standards Association (IEEE-SA) Standards Board. The IEEE develops its standards through a consensus development process, approved by the American National Standards Institute, which brings together volunteers representing varied viewpoint
8、s and interests to achieve the final product. Volunteers are not necessarily members of the Institute and serve without compensation. While the IEEE administers the process and establishes rules to promote fairness in the consensus development process, the IEEE does not independently evaluate, test,

IEEE Standards documents are supplied “AS IS.” The existence of an IEEE Standard does not imply that there are no other ways to produce, test, measure, purchase, marke

Furthermore, the viewpoint expressed at the time a standard is approved and issued is subject to change brought about through developments in the state of the art and comments received from users of the standard. Every
13、 IEEE Standard is subjected to review at least every five years for revision or reaffirmation. When a document is more than five years old and has not been reaffirmed, it is reasonable to conclude that its contents, although still of some value, do not wholly reflect the present state of the art. Us
14、ers are cautioned to check to determine that they have the latest edition of any IEEE Standard.

Any person utilizing this, and any other IEEE Standards document, should rely upon the advice of a competent professional in determining the exercise of reasonable care in any given circumstances. Interpretations: Occasionally questions may ari
16、se regarding the meaning of portions of standards as they relate to specific applications. When the need for interpretations is brought to the attention of IEEE, the Institute will initiate action to prepare appropriate responses. Since IEEE Standards represent a consensus of concerned interests, it
17、 is important to ensure that any interpretation has also received the concurrence of a balance of interests. For this reason, IEEE and the members of its societies and Standards Coordinating Committees are not able to provide an instant response to interpretation requests except in those cases where
18、 the matter has previously received formal consideration. At lectures, symposia, seminars, or educational courses, an individual presenting information on IEEE standards shall make it clear that his or her views should be considered the personal views of that individual rather than the formal positi

Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting

Introduction This introduction is not part of IEEE Std 1619.1-2007, IEEE Standard for Authenticated Encryption with Length Expansion for S
23、torage Devices. The problem of data storage protection has become increasingly important due to legislation that requires the protection of sensitive information. To address this issue, the Security in Storage Working Group (SISWG) is developing standards for the protection of information on storage
24、 media. This standard provides strong data protection by specifying encryption with authentication and length expansion. This standard provides methods suitable for ensuring the privacy and integrity of stored data within applications requiring a high level of assurance. To this end, this standard s
25、pecifies the Advanced Encryption Standard (AES) cipher as used in authenticated-encryption modes. There are many modes of non-cryptographic attacks that are outside the scope of this standard. See B.1 for a discussion. Notice to users Laws and regulations Users of these documents should consult all
26、applicable laws and regulations. Compliance with the provisions of this standard does not imply compliance to any applicable regulatory requirements. Implementers of the standard are responsible for observing or referring to the applicable regulatory requirements. IEEE does not, by the publication o
27、f its standards, intend to urge action that is not in compliance with applicable laws, and these documents may not be construed as doing so. Copyrights This document is copyrighted by the IEEE. It is made available for a wide variety of both public and private uses. These include both use, by refere
28、nce, in laws and regulations, and use in private self-regulation, standardization, and the promotion of engineering practices and methods. By making this document available for use and adoption by public authorities and private users, the IEEE does not waive any rights in copyright to this document.
29、 Updating of IEEE documents Users of IEEE standards should be aware that these documents may be superseded at any time by the issuance of new editions or may be amended from time to time through the issuance of amendments, corrigenda, or errata. An official IEEE document at any point in time consist
30、s of the current edition of the document together with any amendments, corrigenda, or errata then in effect.
