Re-using a keyed AES cipher with GCM cipher mode?

WebApr 11, 2024 · Each GCM_64K_Tables is key dependent, so that the table must be computed at key initialization and stored along with the key. An Encryption/Authentication object will be compatible with a Decryption/Verification object using a different table: // This is OK GCM< AES, GCM_2K_Tables >::Encryption enc; GCM< AES, GCM_64K_Tables >::Decryption dec; 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 and AuthenticatedDecryptionFilter. Each filter combines a block cipher … See more Given two message inputs, aad (additional authenticated data) and confidential data (plain text data), GCM modewill provide authentication … See more Two sample programs are provided for GCM mode.

WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. WebGCM is defined for the tag sizes 128, 120, 112, 104, or 96, 64 and 32. Note that the security of GCM is strongly dependent on the tag size. You should try and use a tag size of 64 bits at the very minimum, but in general a tag size of the full 128 bits should be preferred.
