Truly Efficient $2$-Round Perfectly Secure Message Transmission Scheme
2009
IEEE Transactions on Information Theory
Preserved Fulltext
In the model of perfectly secure message transmission schemes (PSMTs), there are n channels between a sender and a receiver. ...
In this paper, we show the first 2-round PSMT for n = 2t + 1 such that not only the transmission rate is O(n) but also the computational costs of the sender and the receiver are both polynomial in n. ...
For r = 1, Dolev et al. showed that there exists a 1-round perfectly secure message transmission scheme (PSMT) if and only if n ≥ 3t + 1 [2] . They also showed an efficient 1-round PSMT [2] . ...

The formal proofs show that our proposed schemes satisfy all the desired security properties. ...
We first give two constructions of (full) ID-based trapdoor commitment schemes based on RSA and Factoring assumptions respectively and then extend them to non-malleable schemes. ...
The main idea to achieve nonmalleability is to add a three round efficient zeroknowledge proof after committing to a message using the malleable ID-based trapdoor commitment. ...

The proposed protocol works with off-the-shelf 802.11 wireless cards and is secure against eavesdropping attacks that use power analysis. ...
It requires, however, some firmware changes to protect against attacks that attempt to identify the source of packets from their transmission frequency. ...
The number of messages per secret bit is reduced (1 instead of 4), making the protocol more energy efficient. ...
