Phi in cryptography

WebThe phi function of n (n is a counting number, such as 1 2, 3, ...) counts the number of numbers that are less than or equal to n and only share the factor of 1 with n. Example: phi (15) 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 15 has the factors of 3 and 5, so all … WebFull disc encryption is a type of encryption that encrypts your entire computer. This is distinct from other types of file encryption, which only isolate and encrypt individual files within your hard drive. Full disc encryption will protect your computer systems from malicious attacks aimed at your sensitive health care data.

WebOct 4, 2015 · In textbook RSA, the Euler φ function φ(pq) = (p − 1)(q − 1) is used to define the private exponent d. On the other hand, real-world cryptographic specifications require the Carmichael lcm function λ(pq) = lcm(p − 1, q − 1) to define d´ . It is clear that the d´ divides d, and therefore using d´ may be more efficient than using d.
