From phishing schemes to malware delivery and data breaches, email security risks are substantial and constantly evolving. To combat these threats, organizations need robust, future-proof solutions. Enter Public Key Infrastructure (PKI), a technology that leverages cryptography to secure emails through encryption, authentication, and digital signatures.
In this comprehensive pillar blog, we’ll explore the foundational role of PKI in email security, delve into its advanced capabilities, highlight its benefits, and show how eMudhra’s solutions elevate email security to new heights.
A Deeper Dive into PKI: Foundations of Email Security
Public Key Infrastructure (PKI) serves as the backbone of email security, offering a framework to secure digital communications and protect sensitive data. It utilizes asymmetric cryptography, which relies on two keys—a public key and a private key. Here’s how PKI enhances email security:
Key Elements of PKI
-
Public and Private Keys:
-
Public Key: Shared openly and used to encrypt emails.
-
Private Key: Kept confidential and used for decryption, ensuring that even if emails are intercepted, they remain secure without the private keyDigital Certificates:
-
Issued by trusted Certificate Authorities (CAs), these certificates authenticate the identity of users or organizations, ensuring the legitimacy of email senders and recipients.
Certificate Authorities (CAs):
Trusted third-party organizations that issue, revoke, and manage digital certificates. Examples include DigiCert, GlobalSign, and eMudhra.
Public Key Cryptography Standards (PKCS):
Standardized protocols, such as PKCS#7 for digital signatures and PKCS#12 for key storage, govern how cryptography is implemented.
