RSA problem - Wikipedia
WebIn cryptography, the RSA problem summarizes the task of performing an RSA private-key operation given only the public key.The RSA algorithm raises a message to an exponent, modulo a composite number N whose factors are not known. Thus, the task can be neatly described as finding the e th roots of an arbitrary number, modulo N. For large RSA key … WebIn cryptography, key size, key length, or key space refer to the number of bits in a key used by a cryptographic algorithm (such as a cipher).. Key length defines the upper-bound on … stephen p. robbins timothy a. judge
