UMAC: Message Authentication Code using Universal Hashing
Status of This Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Abstract This specification describes how to generate an authentication tag using the UMAC message authentication algorithm. UMAC is designed to be very fast to compute in software on contemporary uniprocessors. Measured spe...
متن کاملComparative Study of DECIM-128 and DECIMV2 in relation to Compact Hash-based Message Authentication Code
constructing compact HMAC (Hash-based Message Authentication Code) is required to maintain integrity and authentication in computationally constrained environments like Wireless sensor networks and RFID. DECIM is a hardware oriented stream cipher submitted to the ECRYPT stream cipher project. It is highly scrutinized stream cipher and is portable to implement hashing for highly compact MAC, whi...
متن کاملAn 80Gbps FPGA Implementation of a Universal Hash Function based Message Authentication Code
We developed an architecture optimization technique called divide-and-concatenate and applied it to a cryptographic message authentication code (MAC). This is based on two key observations: (i) The area of a multiplier and associated data path decreases quadratically and their speeds increase gradually as their operand size is reduced. (ii) Two w-bit universal hash function data paths (each wit...
متن کاملOn the Security of Cipher Block Chaining Message Authentication Code
In [4], Bernstein presented a simple proof of security of Cipher Block Chaining (CBC) Message Authentication Code (MAC) against adversaries querying messages all of which are of the same length. In this paper we show that Bernstein’s proof can be used to prove security of CBC MAC against adversaries querying non-empty messages that are not prefixes of each other. This implies that “length-prepe...
متن کاملThe Security of the Cipher Block Chaining Message Authentication Code
Let F be some block cipher (eg., DES) with block length l. The Cipher Block Chaining Message Authentication Code (CBC MAC) speci es that an m-block message x = x1 xm be authenticated among parties who share a secret key a for the block cipher by tagging x with a pre x of ym, where y0 = 0 l and yi = Fa(mi yi 1) for i = 1; 2; : : : ;m. This method is a pervasively used international and U.S. stan...
