RSA algorithm is a process of encrypting plain text in blocks, every block has a binary value lesser than some n number. The size of block should be less than log (n) or equal to log (n), public-key cryptosystem was implemented by RSA algorithm In this Journal we are going to ...

Security vulnerabilities of the RSA algorithm The RSA algorithm is difficult to crack, provided that it adheres to the recommendations. Several vulnerabilities in RSA have been discovered over the past few years. Those vulnerabilities are: Side-channel attacks ...
摘要: We deal with the RSA encryption algorithm. Its safety is analyzed using the number field sieve method. The algorithm work results allow to define a secret key in a simple way关键词: computational complexity computer networks cryptography RSA encryption algorithm computational complexity computer ...
