 In order to prevent such attacks, it **MUST** be verified that participating
 public keys own the corresponding private key.
 
-Note further that this aggregation scheme is vulnerable to public keys with
-linear relationships. A set of public keys `A` leaking the sum of their private
-keys would allow the creation of a second set of public keys `B` with
-`aggPubKey(A) = aggPubKey(B)`. This would make signatures created by set `A`
-indistinguishable from signatures created by set `B`.
-In order to prevent such issues, it **MUST** be verified that no two distinct
-sets of public keys derive to the same aggregated public key. Note that
-cryptographically sound created random private keys have a negligible
-probability of having a linear relationship.
