This paper presents a novel, yet efficient secret-key authentication and MAC, which provide post-quantum security promise, whose security is reduced to the quantum-safe conjectured hardness of Mersenn...
Encrypt-then-MAC (EtM) is a popular mode for authenticated encryption (AE). Unfortunately, almost all designs following the EtM paradigm, including the AE suites for TLS, are vulnerable against nonce ...
We propose an authenticated encryption scheme for the VMPC-R stream cipher. VMPC-R is an RC4-like algorithm proposed in 2013. It was created in a challenge to find a bias-free cipher within the RC4 de...
In this paper, we present an alternative method to choose ordinary cube variables for Keccak-MAC. Firstly, we choose some good candidates for ordinary cube variables with key-independent conditions. T...
This paper applies non-adaptive group testing to aggregate message authentication code (MAC) and introduces non-adaptive group-testing aggregate MAC. After formalization of its syntax and security req...
This paper presents MergeMAC, a MAC that is particularly suitable for environments with strict time requirements and extremely limited bandwidth. MergeMAC computes the MAC by splitting the message int...
Nowadays, RFID systems have earned an important place in our everyday lives. Its adoption is growing in areas where data security or privacy or both must be guaranteed. Since the RFID tag can be clone...
Keccak is the final winner of SHA-3 competition and it can be used as message authentic codes as well. The basic and balanced divide-and-conquer attacks on Keccak-MAC were proposed by Dinur et al. at ...
The security of a probabilistic Message Authentication Code (MAC) usually depends on the uniqueness of the random salt which restricts the security to birthday bound of the salt size due to the collis...
Outsourcing data storage to the cloud securely and retrieving the remote data in an efficient way is a very significant research topic, with high relevance to secure cloud deployment. With the ever gr...
Probabilistic MAC (message authentication code) is an alternative choice for a stateful MAC where maintaining internal state may be difficult or unsafe. Usually tag of a probabilistic MAC consists of ...
In this paper, we define new RKA security notions for several cryptographic primitives including message authentication code (MAC), public-key encryption (PKE) and symmetric encryption (SE). This new ...
We propose a nonce-based MAC construction called EWCDM (Encrypted Wegman-Carter with Davies-Meyer), based on an almost xor-universal hash function and a block cipher, with the following properties: (i...
Lightweight cryptography strives to protect communication in constrained environments without sacrificing security. However, security often conflicts with efficiency, shown by the fact that many new...
