Integrated Cryptographic Service Facility (ICSF) is a part of the IBM® z/OS® operating system that provides cryptographic functions for data security, data integrity, personal identification, digital signatures, and the management of cryptographic keys. Together with the cryptography features of the IBM Z family, it provides secure, high-performance cryptographic functions (such as the loading of master key values) that enable the hardware features to be used by applications. This IBM RedpaperTM publication briefly describes ICSF and the key elements of z/OS that address different security needs. The audience for this publication is cryptographic administrators and security administrators, and those in charge of auditing security in an organization.
This IBM® Redpaper Redbooks® publication provides a broad explanation of data protection through encryption and IBM Z® pervasive encryption with a focus on IBM z/OS® data set encryption. It describes how the various hardware and software components interact in a z/OS data set encryption environment. In addition, this book concentrates on the planning and preparing of the environment and offers implementation, configuration, and operational examples that can be used in z/OS data set encryption environments. This publication is intended for IT architects, system programmer, and security administrators who plan for, deploy, and manage security on the Z platform. The reader is expected to have a basic understanding of IBM Z security concepts.
This IBM® Redbooks® publication provides detailed information about the implementation of hardware cryptography in the System z10® server. We begin by summarizing the history of hardware cryptography on IBM Mainframe servers, introducing the cryptographic support available on the IBM System z10, introducing the Crypto Express3 feature, briefly comparing the functions provided by the hardware and software, and providing a high-level overview of the application programming interfaces available for invoking cryptographic support. This book then provides detailed information about the Crypto Express3 feature, discussing at length its physical design, its function and usage details, the services that it provides, and the API exposed to the programmer. This book also provides significant coverage of the CP Assist for Cryptographic Functions (CPACF). Details on the history and purpose of the CPACF are provided, along with an overview of cryptographic keys and CPACF usage details. A chapter on the configuration of the hardware cryptographic features is provided, which covers topics such as zeroizing domains and security settings. We examine the software support for the cryptographic functions available on the System z10 server. We look at the recent changes in the Integrated Cryptographic Service Facility (ICSF) introduced with level HCR7770 for the z/OS® operating system. A discussion of PKCS#11 support presents an overview of the standard and provides details on configuration and exploitation of PKCS#11 services available on the z/OS operating system. The Trusted Key Entry (TKE) Version 6.0 workstation updates are examined in detail and examples are presented on the configuration, usage, and exploitation of the new features. We discuss the cryptographic support available for Linux® on System z®, with a focus on the services available through the IBM Common Cryptographic Architecture (CCA) API. We also provide an overview on Elliptical Curve Cryptography (ECC), along with examples of exploiting ECC using ICSF PKCS#11 services. Sample Rexx and Assembler code is provided that demonstrate the capabilities of CPACF protected keys.
Blockchain technology is a digital ledger system that allows for secure, transparent and tamper-proof transactions. It is essentially an often decentralized, distributed, peer-to-peer database that is maintained by a network of computers instead of a single entity, making it highly resistant to hacking and data breaches. By providing greater security, transparency and efficiency, blockchain technology can help to create a more equitable and sustainable world. Blockchain technology has the potential to help mankind in various ways, some of which include but are not limited to: Decentralization and Transparency: Blockchain technology allows for decentralization of data and transactions, making them more transparent and accountable. This is particularly important in fields such as finance, where trust and transparency are critical. Increased Security: Blockchain technology is inherently secure due to its distributed nature, making it very difficult for hackers to compromise the system. This makes it an ideal solution for data and information storage, particularly in areas such as health and finance, where privacy and security are of utmost importance. Faster Transactions: Blockchain technology eliminates the need for intermediaries, reducing the time and cost associated with transactions. This makes it an ideal solution for international trade, remittances and other types of financial transactions, especially in parts of the world where a great number of individuals do not have access to basic banking services. Immutable Record: One of the fundamental attributes of blockchain is its immutability. Once data is added to the blockchain, it becomes nearly impossible to alter or delete. This feature ensures a tamper-resistant and reliable record of transactions, crucial for maintaining integrity in various industries, including supply chain management and legal documentation. Smart Contracts: Blockchain technology supports the implementation of smart contracts, which are self-executing contracts with the terms of the agreement directly written into code. This automation streamlines processes and reduces the risk of fraud, particularly in sectors like real estate and legal agreements. Interoperability: Blockchain’s ability to facilitate interoperability allows different blockchain networks to communicate and share information seamlessly. This attribute is pivotal for creating a unified and interconnected ecosystem, especially as various industries adopt blockchain independently. Interoperability enhances efficiency, reduces redundancy and fosters collaboration across diverse sectors. Leveraging Blockchain Technology: Governance, Risk, Compliance, Security, and Benevolent Use Cases discusses various governance, risk and control (GRC) and operational risk-related considerations in a comprehensive, yet non-technical, way to enable business leaders, managers and professionals to better understand and appreciate its various potential use cases. This book is also a must-read for leaders of non-profit organizations, allowing them to further democratize needs that we often take for granted in developed countries around the globe, such as access to basic telemedicine, identity management and banking services.

Regulatory and industry-specific requirements, such as SOX, Visa PCI, HIPAA, and so on, require that sensitive data must be stored securely and protected against unauthorized access or modifications. Several of the requirements state that data must be encrypted. IBM® i5/OS® offers several options that allow customers to encrypt data in the database tables. However, encryption is not a trivial task. Careful planning is essential for successful implementation of data encryption project. In the worst case, you would not be able to retrieve clear text information from encrypted data. This IBM Redbooks® publication is designed to help planners, implementers, and programmers by providing three key pieces of information: Part 1, "Introduction to data encryption" on page 1, introduces key concepts, terminology, algorithms, and key management. Understanding these is important to follow the rest of the book. If you are already familiar with the general concepts of cryptography and the data encryption aspect of it, you may skip this part. Part 2, "Planning for data encryption" on page 37, provides critical information for planning a data encryption project on i5/OS. Part 3, "Implementation of data encryption" on page 113, provides various implementation scenarios with a step-by-step guide.
