Cryptosysteem
WebThe Okamoto–Uchiyama cryptosystem is a public key cryptosystem proposed in 1998 by Tatsuaki Okamoto and Shigenori Uchiyama. The system works in the multiplicative group of integers modulo n , ( Z / n Z ) ∗ {\displaystyle (\mathbb {Z} /n\mathbb {Z} )^{*}} , where n is of the form p 2 q and p and q are large primes . There are a number of attacks against plain RSA as described below. • When encrypting with low encryption exponents (e.g., e = 3) and small values of the m (i.e., m < n ), the result of m is strictly less than the modulus n. In this case, ciphertexts can be decrypted easily by taking the eth root of the ciphertext over the integers. • If the same clear-text message is sent to e or more recipients in an encrypted way, and the receivers share the same exponent e, b…

Each user participating in the communication has to generate two keys, one is to be kept secret (private key) and one is to make public (public key). Public key cryptosystem can achieve both confidentiality and authenticity.
In cryptography, a cryptosystem is a suite of cryptographic algorithms needed to implement a particular security service, such as confidentiality (encryption). Typically, a cryptosystem consists of three algorithms: one for key generation, one for encryption, and one for decryption. The term cipher (sometimes cypher) is often used to refer to a pair of algorithms, one for encryption and one for decryption. Therefore, the term cryptosystem is most … Webcryptosystem is key theft .
