 ## Use of Prefix to for attack mitigation
 
-The Prefix value specified in the message format calculated in {{sec-sigs}} can be used by a traditional verifier to detect if the composite signature has been stripped apart.  An attacker would need to compute M' = Prefix || Domain || len(ctx) || ctx || M  or  M' :=  Prefix || Domain || len(ctx) || ctx || HashOID || PH(M).  Since the Prefix is the constant String "CompositeAlgorithmSignatures2025" (Byte encoding 436F6D706F73697465416C676F726974686D5369676E61747572657332303235 ) a traditional verifier can check if the Message starts with this prefix and reject the message.
