TL;DR: In this paper, an improved software cryptographic apparatus and method is described, which enables the encryption of the object code of a program so as to enable relocatable code operations and adapts program execution for a mixture of encrypted and non-encrypted code.
Abstract: An improved software cryptographic apparatus and method are disclosed. The apparatus and method enables the encryption of the object code of a program so as to enable relocatable code operations. The apparatus and method will adapt program execution for a mixture of encrypted and nonencrypted code. A particular advantage of the apparatus and method is its accommodation of interrupts and branches while carrying out the cryptographic function.

TL;DR: A cryptographic transformation is a mapping f from a set of cleartext messages, M, to aSet of ciphertext messages, f, so that f(m) should be difficult to infer from f and public knowledge about f.
Abstract: A cryptographic transformation is a mapping f from a set of cleartext messages, M, to a set of ciphertext messages. Since for m e M, f(m) should hide the contents of m from an enemy, f-1 should, in a certain technical sense, be difficult to infer from f(m) and public knowledge about f. A cryptosystem is a model of computation and communication which permits the manipulation of messages by cryptographic transformations.
