Security experts long have maintained that providing any kind of backdoor access to encrypted data as governments everywhere have been demanding is not possible without seriously undermining the overall security provided by encryption mechanisms. Now a pair of researchers from Boston University and Portland State University has developed a first-of-its kind cryptographic technique that they say provides something of a middle ground.
At its core is the notion of a sort of “crumple zone” in cryptographic mechanisms that make it possible – but extremely expensive – for someone to recover keys for decrypting targeted communications, the two researchers said in their paper. “The idea is that, like a crumple zone in automotive engineering, in an emergency situation the construction should break a little bit in order to protect the integrity of the system as a whole,” said the researchers. Far from compromising security, the technique works best when used with the strongest encryption mechanisms.
