TLDR
This paper proposes another way to handle a long ciphertext with a low buffer size by storing and releasing only one intermediate state, without releasing or storing any part of an unverified plaintext and without need of generating any intermediate tag.Abstract:
In authenticated encryption schemes, there are two techniques for handling long ciphertexts while working within the constraints of a low buffer size: Releasing unverified plaintext (RUP) or Producing intermediate tags (PIT). In this paper, in addition to these two techniques, we propose another way to handle a long ciphertext with a low buffer size by storing and releasing only one (generally, or only few) intermediate state, without releasing or storing any part of an unverified plaintext and without need of generating any intermediate tag. In this paper we explain this generalized technique using our new construction sp-AELM. sp-AELM is a sponge based authenticated encryption scheme that provides support for limited memory devices. We also provide its security proof for privacy and authenticity in an ideal permutation model, using a code based game playing framework. Furthermore, we also present two more variants of sp-AELM that serve the same purpose and are more efficient than sp-AELM.read more

Deterministic Authenticated Encryption Scheme for Memory Constrained Devices
TL;DR: A new AE scheme called dAELM, which stands for deterministic authenticated encryption (DAE) scheme for low memory devices, is proposed, which is to use a session key to encrypt a message and share the session key with the user depending upon the verification of a tag.

On the Security of Remotely Keyed Encryption
TL;DR: This paper deals with how to define the security of remotely keyed encryption schemes, since the attacker can take over the slow device and actually take part in the encryption process.

Authenticated on-line encryption
TL;DR: In this article, the authors investigate the authenticated encryption paradigm and its security against blockwise adaptive adversaries, mounting chosen ciphertext attacks on on-the-fly cryptographic devices and propose a generic construction called Decrypt-Then-Mask, and prove its security in the blockwise adversarial model.
