D.S.P.P.: Data Security Pipe Protocol is an original asymetric cryptographic time dependent public auto-key protocol applied to data security. This protocol has been designed for secrecy in data files or end-to-end data communications and to solve problems involving intruders in networks or locally and also to avoid cheating by contractors ... in other words to answer the question:Is it possible for Michael and François to communicate in perfect security without cheating each other and without interference from a 'third party' in the network ...even they are total strangers...? with respect with conviviality and simplicity for use !According to theoretical considerations on the most efficient methods of computing in multi-precision modular arithmetic, we use Mersenne primes of 521, 607 and potentially 1279 binary digits and a random generator of very large period claimed to be O (10174) which presents good statistical proprieties and recently developed by Guinier D. (1986). Auto-public keys are single because they are message-signature-day-time-dependent and change their values at each computer tick I This protocol is applied to digital signatures, notarification, data integrity and confidentiality. The actual implementation in structured Fortran 77 works on a personal computer PC/AT and could be used as well on large scale systems as on networks. Encryption-decryption rate on PC's is O (1000 characters per second) and public or communication keys are generated from 3 seconds to some minutes depending on the key length in use (127, 521, 607 or 1279-bit).
