When using block ciphers, larger, structured amounts of data should not be encrypted in the ECB mode.

BSI: IT-Grundschutz catalogues – 13th version

IBM services include business consulting, outsourcing, hosting services, applications, and other technology management. For security applications that will be used in is long term, bit RSA moduli or subgroup orders of at least bits should be used. Is it ensured that established algorithms are used that were examined intensively by experts and that are not characterised by any known security gaps? The fifth and sixth mechanism use two parallel instances of the first and fourth mechanism respectively, and combine the two results with a bitwise exclusive-or operation.

It is not refundable or transferable and may not be prorated. Manufacturers frequently offer security products using new algorithms that are supposedly “much more secure and even faster” than other algorithms. An IBM part or feature added to a machine without replacing a previously installed part or feature is subject to a full warranty effective on its date of installation. The electronic signatures, as defined in the EU directives and statutory provisions of Germany, must be differentiated from the digital signatures mentioned here.

Telephone support may be subject to additional charges, even during the limited isk period. Other restrictions may apply. Although examining an individual component alone should not be considered justified due to the interaction of each of the relevant effects, it is nevertheless important to know the factors influencing each individual component e.

It is your first step toward helping to protect your investment and sustain high levels of system availability. Flex System Manager Node includes a preloaded software stack.

These parts are to be serviced during the IBM machine warranty period. Reduce ixo number of interfaces, steps, and clicks it takes to manage IT resources.

Hash methods Great isi has been made recently in the cryptographic analysis of hash functions. They are recommended for applications, which require an increased security level against forgery attacks cf. During the warranty period, a warranty service upgrade provides an enhanced level of On-site Service for an additional charge.


Suitable algorithms include, for example, RSA or encryption procedures based on elliptic curves see below for the appropriate key length. The customer is responsible for evaluation, selection, and implementation of security features, administrative procedures, and appropriate controls in application systems and communications facilities. Since numerous keys need to be encrypted by the asymmetric procedure for use in the symmetric procedure before exchanging keys, the asymmetric algorithm should be designed to be slightly stronger.

The following have been designated as consumables, supply items, or structural parts and therefore not covered by this warranty:. Authentication of users or components One simple method of authentication is to query for a password.

IBM Flex System gives forward-thinking companies a way to completely rethink deployment and management of their IT environments; it offers an opportunity to evolve to a more open, agile, and integrated computing system that is dynamically managed from a single vantage point to simultaneously maximize efficiency and innovation. Under certain conditions, IBM Integrated Technology Services repairs selected non-IBM parts at no additional charge for machines that are covered under warranty service upgrades or maintenance services.

Rates and offerings are subject to change, extension, or withdrawal without notice. Buy Standards Purchase the standards and standards-based products you are looking for. If the machine does not function as warranted and your problem can be resolved through your application of downloadable Machine Code, you are responsible for downloading and installing these designated Machine Code changes as IBM specifies.

IBM Flex System Manager is the next generation of smarter computing that integrates multiple server architectures, networking, storage, and system management capability into a single system that is easy to deploy and manage. For performance reasons, no implementations based solely on public key techniques should be used for encryption purposes.

IBM 831-1 repair the failing machine at your location and verify its operation. The Americas Call Centers, our national direct marketing organization, can add your name to the mailing list for catalogs of IBM products.

And we will help you get started with a core support package that includes:. Intelligently manage and deploy workloads based on resource availability and predefined policies. IBM Service provides hardware problem determination on non-IBM parts for example, adapter cards, PCMCIA cards, disk drives, or memory installed within IBM machines covered under warranty service upgrades or maintenance services and provides the labor to replace the failing parts at no additional charge.

Comment on draft standards. All common implementations of public key cryptography use hybrid procedures see also S 3. You must follow the problem determination and resolution procedures that IBM specifies.


IBM Global Financing offers competitive financing to credit-qualified customers to assist them in acquiring IT solutions. At the current time, you can assume you are on the safe side when using the following: When return is required, return instructions and a container are shipped with the replacement CRU, and you may be charged for the replacement CRU if IBM does not receive the defective CRU within 15 days of your receipt of the replacement.

IBM may release changes to the Machine Code. Under IWS, warranty service will be provided with the prevailing warranty service type and service level available for the IWS-eligible machine type in the servicing country, and the warranty period observed will be that 88731-1 the country in which the machine was purchased. In the Federal Gazette, the Federal Network Agency regularly publishes an overview of the algorithms that can be considered suitable for generating signature keys, hashing data to is signed, or generating and examining qualified electronic signatures.

However, we would like to warn you about using unknown algorithms from sources whose cryptographic competence has not been adequately verified. If required, IBM provides repair or exchange service, depending on the type of warranty service specified below for the machine.

IBM will attempt to resolve your problem over the telephone or electronically by access to an IBM website. It should again be noted that an infrastructure of trustworthy third parties must be available for the binding service.

Before users commit to using certain procedures, they should have an exact idea of the requirements they need to place on the confidentiality and authenticity of the data processed 87311- every point of the informationprocessing system. Skip to main content Skip to footer.

We offer service-level and response-time options to fit your business needs. They isi provide additional information to help you select a procedure. Is a currently recommended key length used when using cryptographic procedures? Information regarding potential future products is intended to outline our general product direction and it should not be relied on in making a purchasing decision.
