 It is important to note that cryptographic standards are continuously evolving to address emerging threats and advancements in technology. Therefore, it is crucial to stay updated with the latest standards and guidelines from recognized organizations to ensure the use of secure and reliable cryptographic mechanisms.
 
 # Security services # {#security-services}
-Cryptography may be used to provide several basic security services: confidentiality, integrity, data authenticity and non-repudation. In general, a single cryptographic mechanism may provide more than one service (e.g., the use of digital signatures can provide non-repudation and authenticity) but not all services. And a single security services might require multiple cryptographic mechanisms to be combined (e.g., to be sure that confidentiality is achieved an encryption algorithm combined with a key management system is required).
+Cryptography provides several fundamental security services, including confidentiality, integrity, data authenticity, non-repudiation, and authentication. Often, a single cryptographic mechanism can provide more than one service—for example, digital signatures can ensure both authenticity and non-repudiation—but no single mechanism can cover all services. Conversely, achieving a particular security service may require combining multiple cryptographic mechanisms; for instance, ensuring confidentiality typically requires both an encryption algorithm and a key management system. In the following sections, we will examine each of these security services in more detail.
 
 ## Confidentiality ## {#confidentiality}
 Confidentiality ensures that information is protected from being disclosed to unauthorized parties. It is typically achieved through encryption, which transforms readable data into an unreadable data using a cryptographic key. Only authorized parties that know the correct key can decrypt and access the original information.
