PCLA: A New Public-key Cryptosystem Basedon Logarithmic Approach
A public key cryptosystem is an asymmetric cryptosystem where
the key consist of a public key and a private key. As the public
key is public (known to all), can be used to encrypt the messages.
The private key, kept as secret, can be used to decrypt the
messages by the owner. We describe a new public key
cryptosystem based on logarithmic approach. PCLA with its
simplicity, its very easier to create keys and can be use securely
with low memory requirements. PCLA encryption and
decryption use a mixing system suggested by logarithmic
approach combined with a clustering principle based on
elementary mathematical theory. The security of the PCLA
cryptosystem comes from the interaction of the logarithmic
mixing system with the independence of relatively prime
integers p and q.
