Cryptography key space
WebWhen she applies the shift to encrypt the message, she ends up with a cipher text. The cipher text space represents all possible results of an encryption. When she applies the key, it maps to a unique page in this stack. Notice that the size of the message space equals the size of the key space equals the size of the cipher text space.

In 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 an algorithm's security (i.e. a logarithmic measure of the fastest known attack against an algorithm), because the security of all … See more Keys are used to control the operation of a cipher so that only the correct key can convert encrypted text (ciphertext) to plaintext. All commonly-used ciphers are based on publicly known algorithms or are open source and … See more Even if a symmetric cipher is currently unbreakable by exploiting structural weaknesses in its algorithm, it may be possible to run … See more The effectiveness of public key cryptosystems depends on the intractability (computational and theoretical) of certain mathematical problems such as integer factorization. These problems are time-consuming to solve, but usually … See more Encryption systems are often grouped into families. Common families include symmetric systems (e.g. AES) and asymmetric systems (e.g. RSA and Elliptic-curve_cryptography).
