Say I have a key, an iv and an
AES/GCM/NoPadding encoded string and I want to split this information between three people such that only jointly can they reveal the secret.
Is it safe to just split all this data to three equal chunks and provide to each party in a format "
1/3 of key-
1/3 of pass-
1/3 of iv"? Under "safe" I mean, is it possible to come up with some kind of efficient attack while having 1/3 (or 2/3) of all the data?
