Solomonoff and used

Solomonoff and algorithm
In algorithmic information theory, algorithmic ( Solomonoff ) probability is a method of assigning a probability to each hypothesis ( algorithm / program ) that explains a given observation, with the simplest hypothesis ( the shortest program ) having the highest probability and the increasingly complex hypotheses ( longer programs ) receiving increasingly small probabilities.

In cryptography, key size or key length is the size measured in bits of the key used in a cryptographic algorithm ( such as a cipher ).
Shannon's work on information theory showed that to achieve so called perfect secrecy, it is necessary for the key length to be at least as large as the message to be transmitted and only used once ( this algorithm is called the One-time pad ).
Common families include symmetric systems ( e. g. AES ) and asymmetric systems ( e. g. RSA ); they may alternatively be grouped according to the central algorithm used ( e. g. elliptic curve cryptography ).
As each of these is of a different level of cryptographic complexity, it is usual to have different key sizes for the same level of security, depending upon the algorithm used.
