Schneier on Security: Cryptanalysis of SHA-1

Schneier.com

by Bruce Schneier

February 15, 2005

On Tuesday, I blogged about a new cryptanalytic result -- the first attack faster than brute-force against SHA-1. I wrote about SHA, and the need to replace it, last September.

Earlier this week, three Chinese cryptographers showed that SHA-1 is not collision-free. That is, they developed an algorithm for finding collisions faster than brute force.

In 1999, a group of cryptographers built a DES cracker. It was able to perform 256 DES operations in 56 hours. The machine cost $250K to build, although duplicates could be made in the $50K-$75K range.

NIH study: Risk-taking diminishes at age 25

A National Institutes of Health study suggests that the region of the brain that inhibits risky behavior is not fully formed until age 25, a finding with implications for a host of policies, including the nation's driving laws.

The research has implications beyond driving: Attorneys cited brain development studies as the U.S. Supreme Court considered whether juvenile offenders should be eligible for the death penalty. The court is expected to reach a decision by midyear.

Exceptional Returns: Economic, Fiscal, and Social Benefits of Investment in Early Childhood Development

This study demonstrates, for the first time, that providing all 20% of the nation's three- and four-year-old children who live in poverty with a high-quality ECD program would have a substantial payoff for governments and taxpayers in the future.

As those children grow up, costs for remedial and special education, criminal justice, and welfare benefits would decline. Once in the labor force, their incomes would be higher, along with the taxes they would pay back to society. Download the book for free in pdf.

Medicating Kids: Ritalin Abuse - Statistics

PBS - Frontline

December 22, 2004

While prescriptions for Ritalin (methylphenidate) grew dramatically in the 1990s, reports of its illegal use also rose. Here's the range of official statistics on the problem:

According to the University of Michigan's annual "Monitoring the Future" studies, from 1988-1999 the percentage of seniors who reported using Ritalin without a prescription went from 0.3 percent to 2.4 percent. In fact, in its 1994 report, data indicated that at that time, there were more U.S. high-school seniors who abused Ritalin than there were seniors who were legally prescribed the drug.

Unborn children may be at risk from the shampoos and hand lotions used by their pregnant mothers, it was claimed yesterday.

Women who take slimming tablets during their pregnancy are more likely to give birth to homosexual children, new research has suggested.

An American study of thousands of mothers and their adult offspring has found that medication used to treat thyroid deficiency and amphetamine-based diet pills appeared to have influenced sexual orientation.

Making the Case for Universal Preschool

Ready Set Grow ... CT Kids

When Sacramento Bee editorial writer Susanna Cooper took a year off to study early childhood education as a journalism fellow with the Public Policy Institute in San Francisco, she didn’t know the experience would profoundly change her professional life

Earlier preschool movements, like the push to establish the Head Start program during Lyndon Johnson's War on Poverty, focused on the country’s poorest children and families. But the most recent preschool-for-all effort points to a growing body of evidence that shows that middle- and working-class students are also falling behind the state's most affluent youngsters. They say all children deserve extra help getting ready for kindergarten, especially in a pressurized environment that requires 5-year-olds to master skills that used to be taught in first grade.
