TLS- EN­CRYP­TION AT­TACK IM­PACTS NEWER TLS 1.3

The Asian Age - - Technomics - DC COR­RE­SPON­DENT

The cat- and- mouse chase be­tween the hack­ers and the se­cu­rity of­fi­cial is a never end­ing af­fair. Last week, how­ever, a team of aca­demics re­vealed a new at­tack that can break en­crypted TLS traf­fic, al­low­ing at­tack­ers to in­ter­cept and steal data pre­vi­ously con­sid­ered safe & se­cure, ac­cord­ing to re­ports.

Cit­ing a tech­ni­cal pa­per, ZDnet re­ports that a team of seven re­searchers found a new way to to break RSA PKCS# 1 v1.5, the most com­mon RSA con­fig­u­ra­tion used to en­crypt TLS con­nec­tions nowa­days.

The new cryp­to­graphic at­tack isn't new, per- se. It's yet another vari­a­tion of the Ble­ichen­bacher or­a­cle at­tack.

The orig­i­nal at­tack was named af­ter cryp­tog­ra­pher Daniel Ble­ichen­bacher, who in 1998 demon­strated a first prac­ti­cal at­tack against sys­tems us­ing RSA en­cryp­tion in con­cert with the PKCS# 1 v1 en­cod­ing func­tion.
