Reverse algorithm was previously evaluated as encryption method concluding that its simple adoption is unviable, since it does not assurance the pre-image existence. Variable-Length Encryption Method (VLE) was proposed where a alternative algorithm with extra bits is adopted when pre-image computation is not possible. If an adequate secret key is used with(More)
A cellular automata (CA) model in cryptography is investigated. A previous work analyzed the usage of reverse algorithm for pre-image computation as an encryption method. The main conclusion was that the simple adoption of such method is not viable, since it does not have 100% of guarantee of pre-image existence. A new approach was proposed that uses extra(More)
