- Secretion (Physiol) Any substance or fluid secreted, or elaborated and emitted, as the gastric juice.
- Secretion The act of secreting or concealing; as, the secretion of dutiable goods.
- Secretion (Physiol) The act of secreting; the process by which material is separated from the blood through the agency of the cells of the various glands and elaborated by the cells into new substances so as to form the various secretions, as the saliva, bile, and other digestive fluids. The process varies in the different glands, and hence are formed the various secretions.

- n secretion In physiology:
- n secretion In animal physiology, the process of preparing and separating substances by glandular activity. The product or secretion usually consists of substances previously existing in the blood, such as water, salts, etc., combined with others which have been elaborated by the glandular epithelium from more or less different substances in the blood. The secretion may be eliminated from the body as detrimental, as urine, or it may be used, as the digestive secretions, to serve requirements of the organism or (as the milk) those of its offspring. Secretions which are merely eliminated as detrimental are called excretions. The act of secreting seems, in most instances at least, to be a vital act of the glandular epithelium, and is often, if not always, under direct nervous control.
- n secretion In vegetable physiology, the process by which substances are separated from the sap of vegetables. The descending sap of plants is not merely subservient to nutrition, but furnishes various matters which are secreted or separated from its mass, and afterward elaborated by particular organs. These secretions are exceedingly numerous, and constitute the great bulk of the solid parts of plants. They have been divided into— general or nutritious secretions, the component parts of which are gum, sugar, starch, lignin, albumen, and gluten; and special or non-assimilable secretions, which may be arranged under the heads of acids, alkalis, neuter principles, resinous principles, coloring matters, milks, oils, resins, etc.
- n secretion A substance or product secreted, or elaborated and emitted.
- n secretion Synonyms Excretion, Secretion. See excretion.
- n secretion A mineral deposit formed in a fissure or cavity by growth inward from the walls: contrasted with concretion, which grows outward from a nucleus.

In science:
An alternative approach is to consider the mutual information between the observed data and the secret data.
Statistical Analysis of Privacy and Anonymity Guarantees in Randomized Security Protocol Implementations
Consequently, this measure depends only on the protocol and not on the distribution of the secrets.
Statistical Analysis of Privacy and Anonymity Guarantees in Randomized Security Protocol Implementations
Many of these techniques assume some distribution (mostly uniform) on the secret input space and only provide guarantees for such input spaces.
Statistical Analysis of Privacy and Anonymity Guarantees in Randomized Security Protocol Implementations
For example, an attacker could have some probabilistic model for the relation between secret F and observable data G as well as some guess about the secret facts F .
Statistical Analysis of Privacy and Anonymity Guarantees in Randomized Security Protocol Implementations
The incremental gain in knowledge of the attacker is defined to be the information flow from secret to observable data.
Statistical Analysis of Privacy and Anonymity Guarantees in Randomized Security Protocol Implementations
We then show how we can use traces of the protocol implementation to learn probabilistic dependency graph between the secrets and the observable data.
Statistical Analysis of Privacy and Anonymity Guarantees in Randomized Security Protocol Implementations
It takes two inputs - the secret data S and a set of one or more random numbers R.
Statistical Analysis of Privacy and Anonymity Guarantees in Randomized Security Protocol Implementations
The goal of the randomized protocol is to ensure that it is difficult to infer the value of secret data from the observable events.
Statistical Analysis of Privacy and Anonymity Guarantees in Randomized Security Protocol Implementations
Randomized protocols can be viewed as a lossy communication channel from S to O and can be represented as a tuple hS , O, p(·|·)i where p is the conditional probability distribution of observation given the secret.
Statistical Analysis of Privacy and Anonymity Guarantees in Randomized Security Protocol Implementations
In this particular instance, for each observable variable, it depends on one or more secret variables which would be the parent of the observable variable. Efficient algorithms exist that perform inference and learning in Bayesian networks.
Statistical Analysis of Privacy and Anonymity Guarantees in Randomized Security Protocol Implementations
Since the protocol is only available to us as a black box implementation, we need to learn the edge connectivity of the corresponding Bayesian network to find what secrets determine what observable variables.
Statistical Analysis of Privacy and Anonymity Guarantees in Randomized Security Protocol Implementations
One domain knowledge that we exploit is that the secret variables and the observable variables do not have any intra-dependencies, that is, the observable variables are conditionally independent of each other given the secret variables.
Statistical Analysis of Privacy and Anonymity Guarantees in Randomized Security Protocol Implementations
The structure learning algorithm works by using the mutual information measures between the observable variables and the secret variables.
Statistical Analysis of Privacy and Anonymity Guarantees in Randomized Security Protocol Implementations
The algorithm begins by identifying observable variables which depend on only one secret variable.
Statistical Analysis of Privacy and Anonymity Guarantees in Randomized Security Protocol Implementations
Conservatively max-degree bound can be specified to be the larger of the sizes of the secrets and observables.
