WebMay 27, 2024 · Google Cloud Messaging (GCM) is a service that handles the sending, routing, and queueing of messages between server applications and mobile client apps. … Webshow that GCM maintains its provable security. We also present provable security results of GCM when the nonce length is restricted to 96 bits, in which case GCM has better security bounds than a general case. 2 Preliminaries Let {0,1}∗ be the set of all bit strings, and for an integer ℓ ≥0, let {0,1}ℓ be a set of ℓ-bit strings.

WebApr 22, 2024 · GCM reveals exactly the length of the plaintext, unless you add padding prior to encryption. This is because block ciphers in counter-based modes act like stream ciphers, where the ciphertext (not counting IVs, MACs, or similar) is exactly the same length as the plaintext. CBC only adds a small amount of length masking - any message will be ... WebIn this paper, we study the security proofs of GCM (Galois/Counter Mode of Operation). We first point out that a lemma, which is related to the upper bound on the probability of a counter collision, is invalid. Both the original privacy and authenticity proofs by the designers are based on the lemma. We further show that the observation can be ...
