We describe public key cryptosystems and analyse the RSA cryptosystem, pointing out a weakness (already known) of the RSA system. We define Lucas functions and derive some of thei...
In a series of papers Patarin proposes new efficient public key systems. A very interesting proposal, called 2-Round Public Key System with S Boxes, or 2R, is based on the difficul...
This research paper presents a new system's design and development of the prescription order communication system (POCS) based on the Internet between the hospital and the ph...
— High secure cryptographic systems require large bit-length encryption keys which presents a challenge to their efficient hardware implementation especially in embedded devices...

A new method for updating certificate revocation trees (CRT) is proposed. Efficient revocation of publickey certificates is a current issue in public-key Infrastructure because a ...
