Starting from the definition: A certificate authority or certification authority (CA) is an entity that issues digital certificates.

Organizations are dealing with significant increases in the use of digital identities, and ensuring that the proper security and privacy of these identities that are implemented is critical.

Definition: A digital certificate is a file or electronic password that proves the authenticity of a device, server, or user through the use of cryptography and public key infrastructure (PKI).

Definition: A digital signature cryptographically binds a digital signature certificate, issued by a trust services provider (TSP), to a document using public key infrastructure (PKI) technology.

Definition: Communications encryption in which data is encrypted when being passed through a network, but routing information remains visible. End-to-end encryption is intended to prevent data being read or secretly modified, other than by the true sender and recipient.

Definition: Highly reliable hardware, firmware, and software components that perform specific, critical security functions. Because roots of trust are inherently trusted, they must be secure by design. Roots of trust provide a solid foundation upon which security and trust can be built.

A future-proof way to encrypt sensitive data is now available. Put it to use. 

You need new mathematical ideas, some of which have just been standardised. 

In this article we explore some of the developments for ransomware protection and protection from advanced threats.

Definition: Encryption is a means of securing digital data using one or more mathematical techniques, along with a password or "key" used to decrypt the information.
