IATE Term of the Week: End-to-end encryption


This June the Committee on Civil Liberties, Justice and Home Affairs proposed an amendment that would enforce end-to-end encryption on all digital communications and forbid backdoors that enable law enforcement to access private message data. In the context of the recent cyber-attacks and this ongoing proposal for regulation, the termend-to-end encryptionwas chosen as this week’s IATE Term of the Week.


According to the amendment of the text proposed by the European Commission:

The providers of electronic communications services shall ensure that there is sufficient protection in place against unauthorised access or alterations to the electronic communications data, and that the confidentiality and safety of the transmission are also guaranteed by the nature of the means of transmission used or by state-of-the-art end-to-end encryption of the electronic communications data.

Techopedia.com define end-to-end encryption (E2EE) as a method used for securing encrypted data while it is moving from the source to the destination. Encrypt is explained in Merriam-Webster online dictionary as the act of changing (information) from one form to another especially to hide its meaning. This word first entered the English vocabulary recently, in 1950, and the noun encryption followed about a decade later. It is interesting to point out that this verb was formed from the noun cryptogram, which means “a message written in code.”  Although cryptogram came to English from French, it is based on the Greek verb meaning “to hide.”

This is an example of the magic of terminology! Terms which date thousands of years ago can still be used to explain, describe or define concepts of the present.
