\nTitle: A Classical Analog to Enta
 nglement Reversibility
\n
\nAbstract: 
\nIn this letter we introduce the 
 problem of secrecy reversibility. This asks when two honest parties can di
 still secret bits from some tripartite distribution pXYZ and transform sec
 ret bits back into pXYZ at equal rates using local operation and public co
 mmunication (LOPC). This is the classical analog to the well-studied probl
 em of reversibly concentrating and diluting entanglement in a quantum stat
 e. We identify the structure of distributions possessing reversible secrec
 y when one of the honest parties holds a binary distribution\, and it is p
 ossible that all reversible distributions have this form. These distributi
 ons are more general than what is obtained by simply constructing a classi
 cal analog to the family of quantum states known to have reversible entang
 lement. An indispensable tool used in our analysis is a conditional form o
 f the G\\'{a}cs-K\\"{o}rner Common Information.
