ABSTRACT:
A system for contributing to a concatenation of a first string and a second string may include a communication unit to receive an encrypted representation of a second share of the second string, the second string being identical to the second share of the second string combined with a first share of the second string and to send a rearranged representation of the encrypted representation of the second share of the second string to a second system. The system may further include a processing unit to rearrange a representation of the encrypted representation of the second share of the second string using a length value of a first share of the first string, the first string being identical to the first share of the first string combined with a second share of the first string.
