چکیده
Abstract An authenticated encryption chip with novel nonce generation circuit was developed. This associates the contents and receiving time of plaintext. It will also generate overlapping power compensation for whole chip. The integrated fabricated under SMIC 180nm technology. Under 1.8V VDD, 100MHz global clock, consumption is about 14mW within 50k gates. test result exhibits more than 10 times strength in resistance to side-channel attack unprotected version without increasing hardware cost.

ISAP - Authenticated Encryption Inherently Secure Against Passive Side-Channel Attacks
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 کاملWhitenoise Encryption Implementation with Increased Robustness against Side-Channel Attacks
Two circuit design techniques improve the robustness of Whitenoise encryption algorithm implementation against side-channel attacks based on dynamic and/or static power consumption. The first technique aims to conceal the power consumption and has linear cost. The second technique aims to randomize the power consumption and has quadratic cost. These techniques are not mutual exclusive; their sy...
متن کاملLeaked-State-Forgery Attack against the Authenticated Encryption Algorithm ALE
ALE is a new authenticated encryption algorithm published at FSE 2013. The authentication component of ALE is based on the strong Pelican MAC, and the authentication security of ALE is claimed to be 128-bit. In this paper, we propose the leaked-state-forgery attack (LSFA) against ALE by exploiting the state information leaked from the encryption of ALE. The LSFA is a new type of differential cr...
متن کاملHomomorphic Authenticated Encryption Secure against Chosen-Ciphertext Attack
We study homomorphic authenticated encryption, where privacy and authenticity of data are protected simultaneously. We define homomorphic versions of various security notions for privacy and authenticity, and investigate relations between them. In particular, we show that it is possible to give a natural definition of IND-CCA for homomorphic authenticated encryption, unlike the case of homomorp...
