Fujitsu MHZ2 CJ Series of 2.5” HDDs Earns JIS Security Accreditation

- First HDD line to meet data security standards for government agencies -

Fujitsu Limited,Fujitsu Laboratories Ltd.

Tokyo and Kawasaki, November 04, 2008

Fujitsu Limited and Fujitsu Laboratories Ltd. today announced that the MHZ2 CJ Series of 2.5” hard disk drives (HDDs) with automatic hardware-based encryption, introduced by Fujitsu in April 2008, has become the first HDD line to obtain JIS X 19790(1) Security Accreditation. The accreditation means that these products have met one of the major standards for data security required for the procurement of IT products by government agencies in Japan and signifies that the MHZ2 CJ Series provides the level of data security required by all public agencies in Japan.

In April 2008, Fujitsu announced the MHZ2 CJ Series of 2.5” HDDs. This new series, complying with the 256-bit Advanced Encryption Standard (AES)(2), aims to prevent information leakage from lost or stolen notebook computers and external HDDs.

The MHZ2 CJ Series has now become the first series of HDDs to obtain accreditation(3) under the JIS X 19790 accreditation program - the Japan Cryptographic Module Validation Program (JCMVP)(4).

JCMVP accreditation is granted to products equipped with the appropriate cryptographic algorithms and acting as cryptographic modules to ensure the security of important information such as the encryption key.

In February 2008, the National Information Security Center issued the "Standards for Information Security Measures for the Central Government Computer Systems (Third Edition)(5)."According to the section on "Introducing the Functions for Encryption and Performing Electronic Signatures," selecting products with JCMVP accreditation is an enhanced requirement. With JCMVP accreditation, the MHZ2 CJ Series will contribute to enhancing the security of IT products and system deployments for our customers in both private and public sectors.

Fujitsu is a leader in the design and development of HDDs with next-generation security features. In June 2008, the company was elevated to the status of Promoter Member of the Trusted Computing Group (TCG), which works to develop and disseminate industry standards for security-related technologies. Leveraging its accumulated technology and know-how, Fujitsu will continue offering products that meet its customers’ needs for information security.

  • [1] JIS X 19790

    Cryptographic module security requirements. Japan Industrial Standard equivalent to ISO/IEC 19790 international standard, based on the FIPS 140-2 cryptographic module evaluation standard set by the National Institute of Standards and Technology (NIST) of the U.S. Department of Commerce.

  • [2] 256-bit Advanced Encryption Standard (AES)

    Selected by the NIST, this is the standard form of encryption used by the U.S. government. AES defines three possible key lengths: 128, 192, and 256 bits. The longer the key length, the stronger the encryption.
