Public Key Infrastructure (PKI) is a framework of policies, technologies, and procedures that enable secure electronic communications through the use of cryptographic key pairs and digital certificates. It ensures data integrity, confidentiality, and authentication by facilitating the management of keys and certificates across networks.
A Certificate Signing Request (CSR) is a message sent from an applicant to a Certificate Authority (CA) to apply for a digital certificate. It contains the public key and the identity information of the applicant, which the CA uses to create and issue a signed certificate if the request is approved.
Secure communications ensure that information exchanged between parties is protected from unauthorized access, interception, or tampering. This involves the use of encryption, authentication, and integrity controls to safeguard data confidentiality and authenticity during transmission.
A security protocol is a set of rules and procedures designed to protect data integrity, confidentiality, and availability during communication or data exchange. It ensures that sensitive information is transmitted securely and is safeguarded against unauthorized access or cyber threats.
Secure protocols are essential for ensuring the confidentiality, integrity, and authenticity of data exchanged over networks. They employ cryptographic techniques to protect data from unauthorized access and tampering, making them crucial for maintaining trust in digital communications.
