IDEA (International Data Encryption Algorithm) was developed by Xuejia Lai
and James Massey at the Swiss Federal Institute of Technology. It was
proposed at EUROCRYPT '91:
IDEA operates on 64-bit data blocks using a 128-bit key. No method of
cracking IDEA faster than exhaustive key search (brute force) has been
discovered, despite extensive analysis by professional cryptologers.
As an example of IDEA's strength, imagine an incredibly fast computer that
can brute force a 56-bit DES key in 1 second. This computer would take upto
194 days to crack a 80-bit key, like the one used by the NSA Skipjack
cipher, and upto 149745258842898 years to crack a 128-bit IDEA key.
IDEA is the symmetric cipher used in the famous PGP (Pretty Good Privacy)
encryption software.
