WebI found classes and code for re-using a keyed AES instance with other cipher modes but I can't find anything about GCM and the same sorts of classes don't seem to exist. Is there any way to re-use a keyed/initialized AES instance with GCM? -- -- You received this message because you are subscribed to the "Crypto++ Users" Google Group. WebNext Steps.

Galios/Counter Mode, or GCM Mode, is a mode of operation that uses a universal hash function over a binary Galois field to provide authenticated encryption. The mode is defined in NIST's SP 800-38D, and P1619. GCM is a high performance mode which offers both pipelining and parallelization. See more Given two message inputs, aad (additional authenticated data) and confidential data (plain text data), GCM modewill provide authentication assurances over the aad and provide both confidentiality and authentication over … See more The constructors accept a block cipher parameter (which is usually AES) and an optional GCM_TablesOption parameter. The default GCM_TablesOption parameter is GCM_2K_Tables. A second Crypto++ table offering is … See more Crypto++ 5.6 intoduced a new interface for working with authenticated encryption objects: AuthenticatedSymmetricCipher. Crypto++ exposes GCM through the use of a GCM mode object and a pair of filters: AuthenticatedEncryptionFilter … See more Two sample programs are provided for GCM mode.
