(接上一期) 六.从上述的分析可见,实际上ISO/IEC17025-1999与ISO9001-2000是互相包容的,但又不是完全包容,ISO/IEC17025-1999包容了ISO9001的94版,而没有完全包容2000版,ISO9001-2000包容了ISO/IEC17025-1999的管理要求,而未包容其技术要求. 相似文献

ISO9000族标准和ISO14000族标准发布实施以来,引起了全世界各行各业的高度重视。一些企业和组织花费了一定的时间、精力和资金通过了认证,获得了ISO9000或ISO14000认证证书。他们希望通过广告、宣传资料(包括录像带)及其他方法,让市场了解他们管理着一个已通过ISO9000族标准认证的质量管理体系或ISO14000族标准认证的环境管理体系。近来,国际标准化组织(以下简称ISO)及其成员经常收到来自公司的咨询,这些公司希望允许在他们宣传ISO9000认证的资料中使用ISO标识;其次是ISO发现在一些印刷广告中,把ISO9000认证理解为… 相似文献

At Crypto 1999, Coron, Naccache and Stern described an existential signature forgery against two popular RSA signature standards, ISO 9796-1 and ISO 9796-2. Following this attack, ISO 9796-1 was withdrawn, and ISO 9796-2 was amended by increasing the message digest to at least 160 bits. In this paper, we describe an attack against the amended version of ISO 9796-2, for all modulus sizes. Our new attack is based on Bernstein’s algorithm for detecting smooth numbers, instead of trial division. In practice, we were able to compute a forgery in only 2 days on a network of 19 servers. Our attack can also be extended to EMV signatures, an ISO 9796-2-compliant format with extra redundancy. In response to this new attack, the ISO 9796-2 standard was amended again in late 2010. 相似文献

RFID技术应用越来越广,给人们带来便利的同时安全和隐私问题也相随而生,如何提高RFID系统的安全防范能力已成为该领域的重点研究方向。许多研究者提出了基于RFID空中接口通信的认证协议,但复杂的算法难以适用于符合ISO18000-6C标准的电子标签。论文根据ISO18000-6C标准提出了一种新的适合低成本标签的认证协议,为RFID安全提供了一套解决方案。 相似文献

Cryptanalysis of ISO/IEC 9796-1 总被引:1,自引:0,他引:1

We describe two different attacks against the ISO/IEC 9796-1 signature standard for RSA and Rabin. Both attacks consist in
an existential forgery under a chosen-message attack: the attacker asks for the signature of some messages of his choice,
and is then able to produce the signature of a message that was never signed by the legitimate signer. The first attack is
a variant of Desmedt and Odlyzko’s attack and requires a few hundreds of signatures. The second attack is more powerful and
requires only three signatures. 相似文献

Standards are developed by highly reputed organizations with a genuine intention that the document acts as a reference requirement and specification record for all manufacturers, and in this process the consumer is presented with a list of conforming products that are all interoperable. Active RFID tags and readers are designed with commercial intent by different manufacturers according to the ISO 18000-7 standard. Through intensive research and tests, it has come to our attention that it is possible to design two active RFID systems that in their entirety conform to the ISO 18000-7 standard and yet be not interoperable with each other. From this statement it can be inferred that conformance is not the sufficient condition for interoperability as is popularly believed, but only the necessary or minimum condition to satisfy interoperability. Therefore apart from preliminary conformance testing, it becomes absolutely essential to include additional and supplemental interoperability tests into the verification process of the production cycle. This research primarily establishes the requirement for interoperability testing giving instances where the standard fails to insure interoperable products. The traditional method to test interoperability currently in practice are investigated and their limitations are exposed. Further this research paper introduces an innovative and ingenious methodology to test active RFID systems for interoperability at the physical layer. 相似文献
