Posi­ti­on Paper on Quan­tum Key Dis­tri­bu­ti­on

Joint­ly writ­ten in col­la­bo­ra­ti­on with Euro­pean part­ner agen­ci­es from France, Swe­den, and the Net­her­lands, the Bun­des­amt für Sicher­heit in der Infor­ma­ti­ons­tech­nik (BSI) has published a tech­ni­cal sum­ma­ry docu­ment on Quan­tum Key Dis­tri­bu­ti­on (QKD). It ana­ly­zes the limi­ta­ti­ons and chal­lenges of this tech­no­lo­gy and is inten­ded to help decis­i­on-makers and poli­cy-makers make an infor­med jud­ge­ment about the use of QKD. 
QKD,  that requi­res a spe­cia­li­zed com­mu­ni­ca­ti­on infra­struc­tu­re, has a num­ber of func­tion­al limi­ta­ti­ons and can only be appli­ed in cer­tain niche use cases. Fur­ther­mo­re, it is not yet suf­fi­ci­ent­ly matu­re from a secu­ri­ty per­spec­ti­ve. In order to enable orga­ni­sa­ti­ons to migra­te to a quan­tum-safe envi­ron­ment, a clear prio­ri­ty should be given to the deploy­ment of Post-Quan­tum Cryp­to­gra­phy (PQC) – a tech­no­lo­gy that dif­fers much less from exis­ting cryp­to­gra­phy than QKD. Click here for the posi­ti­on paper.
