“In the annual update to its cryptographic recommendations (TR-02102) [https://www.linkedin.com/posts/stefan-lukas-gazdag-5a30b67a_after-three-years-of-work-we-were-finally-ugcPost-7419043344926023681-abfb], the Federal Office for Information Security (BSI) has, for the first time, called for an end-of-life date for classical asymmetric encryption methods. According to the BSI, these methods should no longer be used on their own by the end of 2031—and by the end of 2030 for highly sensitive applications. Instead, these methods should be combined in a hybrid form with post-quantum cryptography. For classical signature schemes, the sole use of these methods is scheduled to be phased out by the end of 2035.

TR-02102 is also used internationally in many areas as a reference for the state of the art. Compliance with this BSI Technical Guideline is also mandatory for numerous products, such as those used in the processing of classified information.”

BSI President Claudia Plattner: “With the phase-out of classical encryption methods, we are setting new standards. There is no alternative to the transition to post-quantum cryptography; the Technical Guideline now specifies concrete action steps.”
