ISAP - Towards Side-Channel Secure Authenticated Encryption
Side-channel attacks and in particular differential power analysis (DPA) attacks pose a serious threat to cryptographic implementations. One approach to counteract such attacks are cryptographic schemes based on fresh re-keying. In settings of pre-shared secret keys, such schemes render DPA attacks infeasible by deriving session keys and by ensuring that the attacker cannot collect side-channel...

Side-channel attacks and in particular differential power analysis (DPA) attacks pose a serious threat to cryptographic implementations. One approach to counteract such attacks are cryptographic schemes based on fresh re-keying. In settings of pre-shared secret keys, such schemes render DPA infeasible by deriving session keys and by ensuring that the attacker cannot collect side-channel leakage...
متن کاملArtemia: a family of provably secure authenticated encryption schemes
Authenticated encryption schemes establish both privacy and authenticity. This paper specifies a family of the dedicated authenticated encryption schemes, Artemia. It is an online nonce-based authenticated encryption scheme which supports the associated data. Artemia uses the permutation based mode, JHAE, that is provably secure in the ideal permutation model. The scheme does not require the in...
متن کاملSide-Channel Attacks on Symmetric Encryption Schemes: The Case for Authenticated Encryption
Vaudenay recently demonstrated side-channel attacks on a common encryption scheme, CBC Mode encryption, exploiting a “valid padding” oracle [Vau02]. Mirroring the side-channel attacks of Bleichenbacher [Ble98] and Manger [Man01] on asymmetric schemes, he showed that symmetric encryption methods are just as vulnerable to side-channel weaknesses when an adversary is able to distinguish between va...
متن کاملZETA: Towards Tagless Authenticated Encryption
Tag-based message authentication is a popular cryptographic technique to digitally sign messages. However, for short messages, it often incurs additional costs due to large tags. In this paper, we propose a new scheme that achieves tagless message authentication. The scheme leverages a trade-off between character support and complexity of forgery to provide information security and authenticity.
