摘要：The transmission of medical data by mobile
telephony is an innovation that constitutes the m-health or more
generally e-health. This telemedicine handles personal data of
patients who deserve to be protected when they are transmitted
via the operator or private network, so that malicious people do
not have access to them. This is where cryptography comes in to
secure the medical data transmitted, while preserving their
confidentiality, integrity and authenticity. In this field of personal
data security, public key cryptography or asymmetric
cryptography is becoming increasingly prevalent, as it provides a
public key to encrypt the transmitted message and a second
private key, linked to the first by formal mathematics, that only
the final recipient has to decrypt the message. The RSA
algorithm of River and Shamir provides this asymmetric
cryptography based on a public key and a private key, on two
prime numbers. However, the factorization of these two prime
numbers to give the variable N of RSA can be discovered by a
hacker and thus make the security of medical data vulnerable. In
this article, we propose a more secured RSA algorithm with n
primes and offline storage of the essential parameters of the RSA
algorithm. We performed a triple encryption-decryption with
these n prime numbers, which made it more difficult to break the
factorization of the variable N. Thus, the key generation time is
longer than that of traditional RSA.
