A hybrid cryptosystem can be constructed using any two separate cryptosystems: a key encapsulation mechanism, which is a public-key cryptosystem; a data encapsulation scheme, which is a symmetric-key cryptosystem; The hybrid cryptosystem is itself a public-key system, whose public and private keys are the same as in the key encapsulation scheme ...
A major goal in cryptography is to create cryptographic primitives with provable security. In some cases, cryptographic protocols are found to have information theoretic security; the one-time pad is a common example. However, information theoretic security cannot always be achieved; in such cases, cryptographers fall back to computational ...
Hybrid securities are a broad group of securities that combine the characteristics of the two broader groups of securities, debt and equity. Hybrid securities pay a predictable (either fixed or floating) rate of return or dividend until a certain date, at which point the holder has a number of options, including converting the securities into ...
Dynamic KBA is a high level of authentication that uses knowledge questions to verify each individual identity but does not require the person to have provided the questions and answers beforehand.

In science and mathematics, an open problem or an open question is a known problem which can be accurately stated, and which is assumed to have an objective and verifiable solution, but which has not yet been solved (i.e., no solution for it is known).
Hybrid inviability is a post-zygotic barrier, which reduces a hybrid's capacity to mature into a healthy, fit adult. [1] The relatively low health of these hybrids ...
