Abstract. We introduce new and general complexity theoretic hardumptions. These assumptions abstract out concrete properties of a random oracle and are significantly stronger than ...
One-way hash functions are an important tool in achieving authentication and data integrity. The aim of this paper is to propose a novel one-way hash function based on cellular aut...
Abstract. A simple one-way function along with its proposed application in symmetric cryptography is described. The function is computable with three elementary operations on permu...
Non-malleability is an interesting and useful property which ensures that a cryptographic protocol preserves the independence of the underlying values: given for example an encryp...

An one-way hash chain generated by the iterative use of a one-way hash function on a secret value has recently been widely employed to develop many practical cryptographic solution...
