Analysis of RMAC
نویسندگان
چکیده
In this paper the newly proposed RMAC system is analysed and a generic attack is presented. The attack can be used to find one of the two keys in the system faster than by an exhaustive search. Also, a serious attack on RMAC used with triple-DES is presented.

Related-Key and Key-Collision Attacks Against RMAC
In [JJV02] Jaulmes, Joux, and Valette propose a new randomized message authentication scheme, called RMAC, which NIST is currently in the process of standardizing [NIS02]. In this work we present several attacks against RMAC. The attacks are based on a new protocollevel related-key attack against RMAC and can be considered variants of Biham’s key-collision attack [Bih02]. These attacks provide ...
متن کاملMotion Control of Nonholonomic Wheeled Mobile Robot in a Structured Layout
This paper describes the incorporation of active force control (AFC) scheme into two different resolved motion acceleration control (RMAC) models, i.e. RMAC with proportional-plus-derivative (RMAC-PD) and RMAC with proportional-plus-integralplus-derivative (RMAC-PID). The two newly formulated control models are subsequently implemented as the proposed motion controllers for the nonholonomic whe...
متن کاملRetransmission Flow Control Mechanism for Reliable Multicast using Adaptive Caching
In recent years, several network support schemes for reliable multicast were proposed. RMAC(Reliable Multicast using Adaptive Caching) provides router-assisted reliable multicast transport. It improves retransmission efficiency by caching transmitted data adaptively to network condition at RMAC routers. Bandwidth utilization is also improved by dropping unnecessary feedbacks and retransmissions...
متن کاملAn Achievable Rate Region for Relay Multiple Access Channel Based on Decode-and-Forward
In this paper, we model a specific relay channel named relay multiple access channel (RMAC) aiming at providing a clue to select the relay node in multiple access channels such as the uplink of cellular communication system. In this channel, the relay node not only aids to send the information of the source but also sends its private message to the destination. We derive the achievable rate reg...
متن کاملAn Analysis of RMAC
A re ent trend in message authenti ation is the use of a randomizing parameter, su h th a t the authenti ation tag is based not only on the message and the key, but a publi non e whi h is hanged for every authenti ated message. This generally afords a b e tte r se urity proof. However, several new lasses of atta ks are made available by these te hniques. We examine these atta ks, and apply some...
