NTT Develops Secure Public-Key Encryption Scheme
by Nobuki Nakatuji 17 Dec '03

17 Dec '03

http://pr.info.ntt.co.jp/news/news98e/980416.html Nippon Telegraph and Telephone Corporation (NTT) announced today the development of Efficient Probabilistic Public-Key Encryption (EPOC), a highly secure and mathematically verified public-key encryption scheme that encrypts information on the transmission side with a public-key (encryption key) and then decrypts it on the receiver side with a secret -key (decryption key). Encryption technology has become necessary to prevent information on the Internet from being monitored by others without authorization. Public-key encryption is being widely researched as a practical means of encrypting communication for security. The paramount feature of any public-key encryption schemes is ensuring that figuring out the decryption key from the encryption key is as difficult as possible, to prevent unauthorized use of ciphered information. The RSA*1 scheme uses factoring and the elliptic curve encryption scheme*2 uses elliptic curve discrete logarithms, both of which can take a supercomputer a very long time to determine the key. It has not been verified, however, that either scheme provides the necessary security to prevent ciphered information from being broken by a method other than factoring or elliptic curve discrete logarithms. The Rabin encryption scheme*3, which also uses factoring, offers no algorithm other than factoring for computing the complete plain-text, but it has not been proven that any bit of plain-text cannot be computed. EPOC is a practical scheme in that the computer computation workload for encrypting and decrypting is about the same as that for the RSA and elliptic curve encryption schemes. Also, EPOC is a highly secure scheme which uses a trapdoor discrete logarithm*4 as the key mathematical technique and can be broken only by factoring. Factoring is difficult to accomplish, even with a supercomputer, and the probability that an efficient solution to factoring will be found soon is very low, because mathematicians have been studying the problem for years. EPOC ensures that partial, as well as whole, texts cannot be broken. Finally, EPOC uses probabilistic encryption, so re-encrypted text is encrypted differently each time, unlike the Rabin and RSA scheme, which use deterministic encryption. NTT now plans to incorporate EPOC in systems for enhanced security on the Internet. Public-key encryption is used primarily for key distribution, because computation load is greater than that for secret-key encryption*5, so EPOC will be used in existing encryption modules for key distribution. Other applications will also be developed. In particular, EPOC is suitable for electronic voting and anonymous telecommunication since it has a homomorphic property, unlike the RSA, Rabin and elliptic curve encryption schemes. The theoretical details will be presented at Eurocrypt '98 in Finland this June. Notes: *1: The RSA scheme was developed by Rivest, Shamir, and Adleman in 1978 and is based on the difficulty of factoring. It was the first public-key encryption scheme. *2: The elliptic curve encryption scheme was proposed independently by Miller and Koblitz in 1985 and is based on the difficulty of elliptic curve discrete logarithms. The basic technique is based on a scheme developed by Diffie and Hellman in 1976. *3: The Rabin scheme was developed by Rabin in 1979 and is based on the difficulty of factoring. It was the first public-key encryption scheme to verify the impossibility of breaking a complete text without factoring the public-key. *4: A trapdoor discrete logarithm is a newly discovered discrete logarithm problem that can be solved only if a secret-key is known. *5: Secret-key encryption differs from public-key encryption in that the sender and the receiver use the same key for encryption and decryption. ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

LA DA's illegal wiretaps revealed ---LA Times
by David Honig 17 Dec '03

17 Dec '03

Fans of CALEA, take note. Sunday, April 26, 1998 THE STATE Can the L.A. Criminal-Justice System Work Without Trust? By CHARLES L. LINDNER [excerpt] in the wake of the discovery that deputy district attorneys assigned to its narcotics unit have relied on secret wiretaps for years to gather evidence against their clients--and no one, including judges, knew about the practice. Beyond the obvious legal question of whether the district attorney knowingly violated the 4th Amendments's prohibition against unreasonable search and seizure is one that cannot be resolved in court: Can the county's criminal-justice system carry on in an atmosphere of mistrust? ... LAPD officers have avoided revealing the existence of their electronic intercepts using a police procedure known as "the handoff technique." It works like this: Narcotics officers on "Team A" set up a wiretap to gather information on a suspect. Without identifying the source of their information, the officers turn over the wiretap's "intelligence product" to detectives from "Team B," also members of LAPD's narcotics unit. Using the intelligence product, "Team B" officers set about trying to gather facts independently that would provide "probable cause" for a second judge to sign a search warrant targeting another suspect, without the cops disclosing the existence of the first wiretap to the jurist. It is not hard to imagine the potential harm from this police-prosecution malfeasance. If an investigation focused on a pharmacist, for instance, the police would have a taped record of every prescription for every patient and physician who called the pharmacy. By law, these wiretaps are preserved for 10 years, so the potential damage to an innocent citizen having his or her private calls intercepted is significant. What aggravates the misconduct is the likelihood that neither the police nor the "wiretap judge" followed the legal requirement that the police file written progress reports every 72 hours, and that the judge make a decision every 72 hours on whether a tap can continue. There is strong reason to suspect that neither the judiciary nor the Legislature has been "minding the store." For example, a judge issuing a wiretap order must inform any person whose voice was wiretapped within 90 days and supply the person with an inventory of what was recorded. Similarly, Atty. Gen. Dan Lungren is required to provide a detailed report to the Legislature and state Judicial Council each April regarding the number and duration of all wiretaps conducted by every law-enforcement agency in the state. As of last week, neither the Judicial Council nor Chairman John Vasconcellos' Senate Public Safety Committee could find a copy. Finally, no public defender or private criminal lawyer has been given the legally required inventory since 1985, when the secret wiretaps began. According to Public Defender Michael P. Judge, the public record discloses only three reported wiretaps by local law enforcement during 1997--two by the LAPD and one by the county Sheriff's Department. It is simply mind-boggling that, for the last 13 years, on hundreds of occasions when the court or opposing counsel have asked prosecutors whether they have turned over all defendants' and co-defendants' statements, they have been lied to or misled. The danger from these secret wiretaps is not limited to suspected criminals. According to statistics published by the Administrative Office of the United States Courts, which oversees "authorized" federal wiretaps, each wiretap order of roughly 40 days in length results in the interception of an average 2,139 conversations involving 84 separate persons. The statistics also note that the average tap produces incriminating information less than 20% of the time, resulting in the arrest of two suspects and the conviction of a single individual. If, as a police narcotics detective testified in the Gaxiola case, there have been hundreds of secret "handoff" taps and electronic intercepts, by extrapolation, thousands of Los Angeles residents have had their private telephone conversations secretly and illegally monitored by LAPD. The public defender has filed an unprecedented class-action habeas corpus petition with Superior Court Presiding Judge Robert W. Parkin on behalf of all past, present and future public defender clients. It seeks to discover whether the prosecution denied thousands of defendants a fair trial by hiding the true source of its information, i.e., secret wiretaps. If secret wiretaps were used and the evidence was concealed from the defense, then thousands of men and women were illegally convicted and incarcerated. Should this unhappy scenario play out, the criminal justice system could well be irreparably damaged, its credibility in the public mind ruined. Yet, even if events keep the convicted behind bars, the loss of trust between prosecutor and defense lawyer may never be fully recovered. The problem defense lawyers and criminal judges face today is that they have never had so many prosecutors lie for so long about so much, which may have resulted in the unconstitutional convictions of so many. http://www.latimes.com/sbin/iawrapper?NS-search-set=/3544b/aaaa004Kx44b35f&N S-doc-offset=0&NS-adv-search=0& ------------------------------------------------------------ David Honig Orbit Technology honig(a)otc.net Intaanetto Jigyoubu "I actually thought Silicon Valley was where women went to get fixed." ---LA Mayor Richard Riordan 98.02.19

Schneier on Smartcards and Holding Secrets
by David Honig 17 Dec '03

17 Dec '03

Bruce wrote a short letter to a trade mag (Internet world? I've lost it since) worth reporting. The jist was, if a smartcard contains Bank Secrets but is held by customers which do not share the same goals/responsibility as the owner of the secrets, this is *poor security design*. ------------------------------------------------------------ David Honig Orbit Technology honig(a)otc.net Intaanetto Jigyoubu "I actually thought Silicon Valley was where women went to get fixed." ---LA Mayor Richard Riordan 98.02.19
