Public confidence in electronic banking and commerce may  be lost if an administration security proposal delays secure encryption of   on-line networks, Jim Rudd, a Wells Fargo Bank vice president, said   Wednesday.     
The debate is holding back the implementation of "strong cryptography,"  making security breaches more likely, Mr. Rudd told the Senate Commerce's   science, space and technology subcommittee.   
  
The administration has proposed a global "key" escrow management  structure, in which a trusted third party holds the decoding key to an on-   line encryption system. That system would subordinate security and the   privacy needs of the public to "law enforcement and national security   concerns," Mr. Rudd said in his statement.       
Key escrow is needed for law enforcement and intelligence purposes,  according to administration officials. The Senate panel's hearing Wednesday   focused on the development of electronic commerce.   
  
The National Research Council recently released a report recommending  that the government explore alternatives to key escrow. The council is a   private, nonprofit institution with a congressional directive to provide   advice on science and technology.     
In his testimony, Mr. Rudd endorsed legislation sponsored by Sen. Conrad  Burns, R-Mont., that would prevent government-mandated key escrowing   systems and relax export controls on encryption technology. Mr. Rudd   explained that the bill would promote the development of encryption   techniques, products, and infrastructures.       
The administration's key escrow proposal would add a financial burden to  legitimate commercial users of on-line networks, while not achieving its   goal of disadvantaging criminals hoping to crack the system, Mr. Rudd   added.     
  
The government should encourage private sector efforts to build  certification authorities, which would support encryption technology to   verify "message authenticity" through cryptography such as digital   signatures, authentication and access controls, non-repudiation, secure   time/date stamps, and integrity checks, Mr. Rudd said. But this technology   would not protect the contents from being exposed.         
He added that Wells Fargo expects electronic transactions to increase at  an annual rate of 20% in the next four years, 10 times the expected rate   for paper-based cash and check transactions.
