Efficient Sealed-bid Auction using Hash Chain

2001
This paper proposes the first sealed-bid auction method which uses only hash function. We use a hash chain to commit a bidding price. By using the hash chain, we can drastically reduce the time needed for bidding and opening bids. If we use a practical hash function e.g.

Hash Chains at the Basis of a Secure Reactive Routing Protocol

2012
Presently, the main concern of ad hoc routing protocols is no longer to find an optimal route to a given destination but to find the safe route free from malicious attackers. Several secure ad hoc routing protocols proposed, in the literature, are based on public key cryptography which drawback is to consume much more resources and decrease ...
