The digital world we live in runs on codes and keys. Every time you tap your phone or buy something online, these systems work to keep your information safe.
At Arizona State University, a special team is building better ways to protect our digital lives. Their work helps the apps and websites we use every day stay secure.
“The basics of cryptography are really all about trust,” says Gail-Joon Ahn, who leads security research at ASU. “When we shop online, we need to know our information stays private.”
Cryptography means turning regular information into secret code. Only people with the right key can unlock and read it. It’s like having a special language only certain people understand.
ASU’s researchers focus on making these systems stronger against hackers. One project looks at quantum computers, which could break today’s security codes.
“We’re preparing for tomorrow’s threats today,” explains Ming Zhao, a computer science professor. “Quantum computing will change everything about digital security.”
The team isn’t just working on defense. They’re creating new ways for our devices to talk to each other safely. This matters for smart homes, medical devices, and self-driving cars.
Students at ASU get hands-on experience with these cutting-edge projects. They learn by solving real security problems, not just reading about them in books.
“My research on secure cloud systems actually started as a class project,” says Maya Williams, a graduate student. “Now it might help protect hospital data.”
The work extends beyond campus. ASU partners with government agencies and companies to test new security ideas. These partnerships help turn research into real-world solutions.
One exciting project involves using artificial intelligence to spot unusual computer activity. The system learns what normal looks like, then flags anything suspicious.
“Think of it like a security guard who knows everyone in the building,” says Zhao. “If someone new shows up, they notice right away.”
These advances help everyone, not just tech experts. Better security means fewer data breaches and identity theft problems for regular people.
The researchers also study how people interact with security features. The strongest protection isn’t helpful if it’s too complicated for people to use.
“We design with humans in mind,” Ahn notes. “Security should protect you without getting in your way.”
Looking ahead, ASU’s team sees big challenges as more devices connect to the internet. Each smart device needs protection, from refrigerators to factory robots.
The number of connected devices worldwide will reach 30 billion by 2025. Each one needs security built in from the start, not added later.
ASU’s work helps create standards for this growing digital world. Their research influences how companies build security into new products.
“Today’s students will create tomorrow’s security solutions,” says Ahn. “We’re teaching them to think like defenders and attackers.”

As our digital lives grow more complex, ASU’s research helps keep our information safe. Their work reminds us that good security should be invisible – working hard while we barely notice it’s there.
