![]() ![]() Integrity Protection: Message Authentication Codes (MACs).Īccording to NIST SP 800-57 Part 1, many algorithms and schemes that provide a security service use a hash function as a component of the algorithm.Authentication of End Devices: Pre-shared symmetric keys, Trusted certificates, Trust Anchors.Encryption: Symmetric encryption keys, Asymmetric encryption keys (public and private).There are a diverse set of key types and certificates to consider, for example: Once the protocols and algorithms are understood, you can begin to define the different types of keys that will support the application's objectives. Once the understanding of the security needs of the application is achieved, developers can determine what protocols and algorithms are required. Keys to create the data encryption keys.Confidentiality of data at rest and confidentiality of data in transit.For example, the application may require: Begin by understanding the security objectives of the application which will then drive the selection of cryptographic protocols that are best suited. However, an analysis of the real needs of the application should be conducted to determine the optimal key management approach. Application developers oftentimes begin the development of crypto and key management capabilities by examining what is available in a library. We have provided recommendations on the selection of crypto suites within an application based on application and security objectives. ![]() ![]() Applications that are required to transmit and receive data would select an algorithm suite that supports the objective of data in transit protection. Selection of the cryptographic and key management algorithms to use within a given application should begin with an understanding of the objectives of the application.įor example, if the application is required to store data securely, then the developer should select an algorithm suite that supports the objective of data at rest protection security. Identify the cryptographic and key management requirements for your application and map all components that process or store cryptographic key material. key compromise, recovery and zeroizationįormulate a plan for the overall organization's cryptographic strategy to guide developers working on different applications and ensure that each application's cryptographic capability meets minimum requirements and best practices.key life cycle management (generation, distribution, destruction).It is important to document and harmonize rules and practices for: This Key Management Cheat Sheet provides developers with guidance for implementation of cryptographic key management within an application in a secure manner.
