History of RSA:
The RSA algorithm is a security method used by many companies and internet users today that protects fragile data when it is being sent from one computer to another and has the potential to be stolen. Cryptography itself has roots in battlefield messengers carrying plans or information that is critical to the success of his own side. RSA however uses a different approach, using an asymmetric key cryptosystem where messages can be sent mutually without any prior contact or shared knowledge. RSA cryptology uses modular exponentiation of prime numbers in order to encrypt data using basic prime patterns. The RSA method is an algorithm used by most computers today to encrypt and decrypt potentially vulnerable data that is sent …show more content…
For the RSA algorithm, the answer is no—for now.
P≠NP means that a problem that is easily checked by a computer is not necessarily easily solved by a computer. This is often called a one-way function, a term coined by Whitfield Diffie and Martin E. Hellman in their paper laying out the necessities for a new type of cryptography for the digital age . The Clay Mathematics Institute includes the P vs NP problem as one of their Millennium Problems and will give one million dollars to anyone who can solve it. In RSA, which was modeled and highly influenced by the Diffie-Hellman paper, this means that it is easy for a computer to check the prime factorization of a number when given the answer. It simply has to multiply all the primes together and if it is equal to the original number, then the answer is true and verified. However, there does not …show more content…
This message is separated into blocks that are smaller than N, and in practice, blocks are typically one binary order smaller than N.
Block size=2^k when 2^k<N≤2^(k+1)
A hash function converts plaintext into numerical values (i.e. A=01, B=02, etc.) however some hash functions are built into a padding scheme. A padding scheme is a manipulation of data by the sender by encrypting the text prior to the RSA encryption (however padding schemes often include multiple steps and instructions for them are pre-determined by the receiver’s program). This prevents attacks where multiple messages are stolen and compared with XOR cryptographic hashes. The most common form of padding is the ISO/IEC 9796-2.
C is the ciphertext that is sent over the internet or server that is subject to being intercepted by
