IBM develops algorithm that encrypts and authenticates simultaneously
IBM has developed an important step to faster and more efficient security
for e-business -- a new algorithm that simultaneously encrypts and
authenticates information.
Previous approaches to ensuring secure communications required performing
encryption and authentication in separate steps. The new algorithm,
invented by IBM researcher Charanjit Jutla, accomplishes the same tasks as
the previous techniques in about half the time.
Equally important, the new algorithm can be even more effective on
highly-parallel systems. Previous schemes couldn't take full advantage of
the parallel processing capabilities offered by modern hardware.
