Abstract: A provable security methodology for the cryptosystems ensuring information privacy and authenticity is discussed. A simplified version of the well-known estimates for the provable security of the AEAD-cryptosystem GCM with an initialization vector of fixed length is proposed. Under the same conditions an estimate for the provable security of GCM modification is obtained. A comparative analysis of the considered cryptosystems is provided.

Keywords: AEAD-cryptosystem, GCM, provable security.
