Summary

Computer scientists from UCLA have developed a secure, one-way communication technique similar in concept to mailing a lock box and later mailing the key to open the lockbox. The technique was developed to ensure messages sent over a network are not altered. The new innovation has wide applications that could benefit many businesses.

Extended Discussion Questions

• The article mentions several examples of “secure multi-party computation”, where multiple parties need to determine whether their data matches without revealing it to each other. Can you think of any other examples?
• Generally, can you think of other scenarios where data integrity (i.e., guaranteeing data hasn’t been tampered with) is important?
