What is ISO/IEC 9797-1:2011 ?

ISO/IEC 9797-1:2011 is an essential international standard that outlines the cryptographic techniques used for securing message authentication codes (MACs) and their related algorithms. It is an essential tool for ensuring the integrity and authenticity of financial transactions.

ISO-IEC 9797-1:2011 is an international standard that provides guidelines for cryptographic techniques used in security systems. It specifies a message authentication code (MAC) algorithm, also known as HMAC-MDThis algorithm ensures the integrity and authenticity of messages being exchanged between different entities.

The purpose of ISO-IEC 9797-1:2011 is to provide a unified and standardized method for implementing cryptographic techniques for message authentication codes. It aims to prevent unauthorized access, tampering, and interception of sensitive information, which can cause significant security risks in financial transactions.

ISO-IEC 9797-1:2011 provides a framework for the development of MAC algorithms that are resistant to various types of attacks, including brute force, differential, and linear probing attacks. It also includes guidelines for key management and distribution to ensure the security of the MAC algorithm.

In addition to ensuring the security of message authentication codes, ISO-IEC 9797-1:2011 also provides guidelines for the development and implementation of security protocols for financial systems. This standard is widely used in the financial industry to secure online transactions and protect sensitive information.

In conclusion, ISO-IEC 9797-1:2011 is an essential international standard for securing message authentication codes and their related algorithms in financial systems. It provides a unified and standardized method for the development and implementation of cryptographic techniques to ensure the integrity and authenticity of financial transactions.
